blown in insulation

QUESTION:

I am having my attic insulated through a state program that will save me a lot of money. The contractors use blown in insulation, I believe made from recycled paper that may have ink on it. My concern is that when further work is done in the attic such as installing a ridge vent or removing mold, that the cellulose will be disturbed and tracked into the living space. It seems that any time a person went into the attic that they would track or spill some of the cellulose.

I am not sure if this is healthy insulation to have in the attic. it will be sitting on top of the existing traditional fiberglass insulation. I am also not sure how risky it would be if a bit of the dust tracked or trickled into the living space.

Does any one have experience with blown in insulation?

What are the risks, if any?

Replacing Fiberglass insulation in an unfinished attic

QUESTION:

Dear Debra,


I have read your recommended safe solutions for insulation in "Home Safe Home". I have also searched the Q&A section.

However, it is not clear to me if the advice givens covers unfinished attics.

We currently have blown fiberglass insulation on the floor of the attic. It has been there at least 20 years.

On the wall adjoining of the attic that adjoins a room, there is fiberglass batting with a layer of plastic over it. There is no drywall covering the fiberglass on that wall.

There is no insulation on the sloping roof portion of the attic.

How can we safely and cost effectively remediate?

What is a suitable replacement insulation for an unfinished (open cavity) attic?

While we do not go into the attic on a daily basis, we may go in there once a month or so, and it also adjoins a room that will be used daily by a MCS person.

Formaldehyde-Free Fiberglass Insulation

QUESTION:

We are considering using formaldehyde-free fiberglass insulation in our new home, and have three questions:

Would you consider the acrylic binders used to be a problem?

Anything else to look out for (presumably batts without paper or plastic covers would be best)?

Can anyone recommend specific brands?

I have often heard Miraflex by Owens Corning recommended, but they stopped producing the product several years ago.

Expanding insulating foam for window installation

QUESTION:

Hello Debra,

In a few weeks I will be installing some new windows in my home. The contractor has recommenced using expanding foam around the windows to seal openings that would let air infiltrate into the house. The product he wants to use is "Great Stuff: Window and Door".

This product does not appear to be a wise choice for someone with chemical sensitivities. The MSDS sheet says it may cause allergic respiratory reactions, pulmonary edema and central nervous system depression.

Do you know of an alternative non toxic product for filling cavities around newly installed windows?

Fire caulk

QUESTION:

Hi Debra,

I was wondering if you know of the least toxic "fire caulk" available. I am not sure but I believe fire caulk is used to seal spaces as a barrier to smoke of any kind. I live in an apartment complex and have started to smell cigarette and marijuana smoke in our unit. The building assures us that each individual unit is self-contained and fire proof, but we are not smoking so it must be coming in from another unit. I mostly smell it in my air conditioner closet with pipes that run up and down, so I think that space around the pipes may be where the air is coming from. The building said they would seal it up with fire caulk but I don't want to try to get rid of one toxin by adding another, especially because we have a newborn in our home. Any advice would be much appreciated. Thank you.

Exterior wood preservative

QUESTION:

Hi Debra,

Can you recommend an "MCS-safer" exterior wood preservative?

We are building an above-ground cabin (6-8 inches above ground). Instead of using pressure treated wood, we plan to use untreated Hemlock lumber. (We are finding Hemlock less smelly and less reactive than Pine). But we need something to preserve the exterior Hemlock, specifically for the joists and the underside of the cabin. We know we can use Vermont Natural Coatings for the interior wood, as you suggested that in another post of yours. But what can we use for an exterior wood preservative?

We are thinking of using LIFE TIME WOOD TREATMENT product, found here:

www.valhalco.com/index.htm

Have you heard of it or do you have any other suggestions? This is from their website:

"LifeTime Wood Treatment is made up of naturally occurring plant and mineral substances, combined in a special, 60 year old recipe handed down through generations of a family of craftsmen. A safe chemical free product. LifeTime contains absolutely no solvents. Wood treated with LifeTime is completely harmless to all living things."

DriCore Subflooring

QUESTION:

Hi Debra,

We're planning on covering our basement concrete floor with DriCore subflooring. We will seal the floor with an AFM/Safecoat urethane after installation. The subfloor will become the floor, as it will not be carpeted or tiled. The DriCore MSDS, link here www.dricore.com/en/pdf/msds.pdf, says it has has phenol formaldehyde resin in the core. I talked with the manufacturer, (www.DRIcore.com and phone 1-866-976-6374) who said the panels are sealed with a water-based acrylic sealant. I will have my husband do all cutting outside, to decrease any chemical dust in the basement.

My question...will the formaledhyde offgas? From the MSDS information do you see any potential problems?

This is the only option that I found that will work for the present situation with our basement floor, whioh has very old red concrete stain that "runs" when it gets wet and leaves a powdery dust on shoe soles. We haven't been able to get it washed off in the 24 years we've lived here. Half the floor is also covered with old lineoleum tile squares over the red stain. I don't know if there is asbestos in the tiles. The other half was painted over the stain, and the paint is now wearing off. The DriCore representative said Dricore can be installed over the top of the present floor as is....that's a huge selling point for us. I want to be as sure as possible that I won't have problems before making this costly purchase.

Thanks for all the work you do to help us improve our health, Debra.

Insulated Concrete Forms - ok for MCS? Other wall material options?

QUESTION:

My husband and I are researching Insulated Concrete Forms for our soon-to-be constructed 'safe house'. Do any of you with MCS have a specific brand of ICF that you can recommend (or not!)?

We are interested in using ICFs for our walls (we have no basement in the design) - we live in upstate NY so we need a well insulated wall system.

I have read endless debates on green building websites regarding the safety of polystyrene used in many ICFs, as well as the blowing agent used to expand the styrene beads, and the flame retardants that are often added. I want to get beyond the theoreticals and hear directly from people with MCS. My husband is gung-ho and ready to use IFC's.... I am worried about the safety, but can't find anything to recommend that would be better. We live in a very eco-conscious town, and lots of folks have used Ecoblock brand and Rastra, and contractors know how to install them.

We briefly considered AAC (aerated autoclaved concrete) but it does not really have enough R-value to be of much use in this climate, and the nearest distributor appears to be in Georgia and no one uses it around here.

There is an Air Krete installer in our town, but I wasn't sure what to use on the interior/exterior cladding and for framing that would be nontoxic, not smelly, and be combatible with the Air Krete.

We expect some level of offgassing to take place despite our best offorts, and are planning to install an HRV/HVAC system.

Thanks so much!!'

Durisol - MCS friendly building material?

QUESTION:

Greetings,
I have moderate MCS and am designing and building a small 'safe house' for our family, in the hopes that with less of a toxic load, my health won't get any worse - and will hopefully improve!

Do any of you who are chemically sensitive live in, or safely spent time in, homes that are built with Durisol blocks? I have found some info about Durisol on various green building sites, but no specific testimonials or claims about their safety for chemically sensitive folks. For those of you who aren't familiar with this product, here is more info:

www.durisolbuild.com

Durisol is a cement block with 'mineralized' woodchips added for insulation (the wood is supposedly all new untreated softwood leftover from manufacturing). The resulting product is supposedly completely inert, nontoxic, won't rot, is impervious to insects, durable, etc. You can apply stucco and plaster directly to it.

Sounds good if it's true. Should I trust the following claim, that this mysterious process results in no chemical residue?

"Mineralization is the proprietary process by which we remove the sugars from the wood and render the material completely inert, and no longer susceptible to rot or termite damage. The wood then becomes an inorganic aggregate similar to stone aggregate in concrete. Durisol is also known as “wood-concrete”. It is the mineralization process that allows the cement to hydrate or “strengthen” in the presence of wood particles.

The mineralization process is an interim process only and all Durisol products, once made, are comprised of cement and wood fiber only. There are no residual chemical properties whatsoever from the wood processing."

We have looked into other, less expensive, brands of ICF's and I am very concerned about the polystyrene in many of them, and the flame retardants. We would need to use the optional rock-wool inserts with the Durisol blocks to achieve a decent R-value for our climate (upstate NY). Would you use the Durisol and rockwool combination, or something else entirely? If we wanted to be paranoid, we could also put foil-backed sheetrock on the interior, although it is tempting to just use a natural plaster finish.

Many thanks!!

This Old House

QUESTION:

Dear Debra and readers

I moved to Michigan 5 years ago from California and started a remodel of an older home with my fiance. Having an auto immune disease and the meds required to control it must have set off a MCS reaction and I was very sick for a couple of years.

I moved out of that house and in with my mom who also has an older home. It was built in 1939. There are old carpets, dirty vents and much needed painting projects along with a small kitchen upgrade to complete. I have Hunter air purifiers all over that handle dust and pollen but not sure they could handle a remodel.

My question is where do I start to improve. I have my MCS somewhat under control but could be much better if I could get this old house fixed. There are covered hardwood floors throughout the home. I want to avoid ripping carpets and painting all at one time. Which would be better for my MCS? Do I go for the carpets first? My budget is small so I would welcome any ideas on where to get the biggest bang for my buck as I stumble through this project.

Thanks

Floor Soundproofing Material

QUESTION:

Hi Debra,

I live in a downstairs apartment and the sound transfer between the two floors is terrible!

I did a lot of research into various underlayment products because the upstairs floors are about to be replaced.

I will probably be paying for the flooring and underlayment out of my pocket (otherwise the landlord is just going to put down cheap carpet), so I'm thinking Seagrass Matting from World Market (which by the way readers, IS treated with pesticides...I called and asked them) BUT I was able to offgas it to the point that it no longer caused my eye to twitch (!), the last time I installed it, by using an ozone machine (an "Aranator") for 30 days and didn't go in the room at all while it offgassed.

But back to the soundproofing....

My 2 best options of a soundproofing product for under the Seagrass Matting are Cork, and a product called "Step Above, Plus".

Step Above Plus, is made of Polyolefin resin, which Debra has already addressed in her answer to a reader's question about plastic bags....It's a petroleum product.

BUT I am wondering how toxic (if at all) it would be as a floor underlayment, under a breathable, seagrass mat. Obviously it's not great for our environment, but it's also more durable and less expensive. The company SAYS it has no VOC's and no smell...

Do you think a product that is made of polyolefin resin could impact my very sensitive health/recovery process? I've heard that cork also can put off a smell of some sort, so I'm a little worried about that too.

I don't THINK I'll be living in those rooms, but I'd like the option, in case I decide to move into that other part of the house at some point.

Thanks!

Marvin Fiberglass Windows

QUESTION:

I purchased several Marvin Fiberglass windows and had them installed two and one-half weeks ago. Right after installation we smelled a strong acrylic odor throughout the house, which has only abated a little bit.

After two weeks of research I discovered that the fiberglass is actually coated with something called "acrylic capstock". I have searched everywhere and cannot find out how harmful this odor is and when it will stop outgassing.

I have respiratory problems if I am in the house longer than a couple hours. Fiberglass is being touted as environmentally friendly and safe for sensitive individuals, but they don't ever mention the acrylic outgassing.

Does anyone know anything about this product and how I can find out how harmful it is to have my children sleeping in these rooms.

Finding Building/Remodeling Advice for MCS

QUESTION:

I read with interest about heating up a newly painted home in order to have it outgass more quickly! However, here in Hawaii, we generally don't have heaters in our homes - it is warm enough and humid enough that no one would ever turn them on unless living at high elevations during the "winter" season. So: what would you suggest for someone with MCS when trying to find products with which to build or refurbish a home with?

We have read about people researching products, installing what had been touted as "safe" and not offgassing bad chemicals into the air, painting with no-VOC paint (only to learn there are other chemicals IN those paints that do also offgass), etc, only to move in and then find they cannot tolerate living in the house! One is then relegated to a porch or a ?tent - but then, can one tolerate the fireproofing on that tent??! Very daunting. There is also the problem of contractors SAYING they have installed whatever, only to find out later that they haven't (they charge the home owner for the mor expensive alternative, and then, install something else - and pocket the difference!) - and worse yet, they have subsequently moved on and are no longer in business, so there is no legal recourse. These scenarios have been in our local papers and on TV programs as "consumer beware" items. All of this has set us back from doing anything, as we are NOT contractors, know little about the building business, etc. and are not sure we would be able to protect ourselves for the outcome, which we would like to be positive, in this process.

Any help anyone can lend would be appreciated - is there any kind of "resource" one can look up locally, ie, in phone book (under environmental something-or-other? I can't seem to find anything other than commercial type resources, or environmental testing at job sites, etc), who can act as a consultant for this type of thing, in order to insure proper and safe products are chose and then actually USED by the contractor? What type of certification does such a person have to have (ie, what certification would we be asking if they have?) I do have your new book as well, and have been busily printing off information from your site for our folder on safe home products! MANY thanks for your invaluable assistance with all this!

toxicity of airport turned into neighborhood

QUESTION:

Hi again!

We are getting ready to move and are very strongly considering a neighborhood in denver called stapleton. This was formerly the denver airport. I have some concerns over whether this location could be a potential toxic nightmare! I have asked the people running it and they assure me that they have been extemely careful in cleaning it up and making sure no chemicals are left behind. But of course they would say that! How do I know for sure?? I have checked the scorecard website but unfortunately it pretty much encompasses all of denver county, which is a big place so it is really hard to tell whether stapleton is of the same level, better, or worse. The neighborhood has been named one of the top 10 greenest neighborhoods in america but I think that has more to do with being enviromentally conscious. While of course I support that, it is just as important to me to live in a safe, nontoxic environment.

Do you have any knowledge of airports turned neighborhoods, or similar things, or can you please point me in a direction to dig deeper?

how to make a brand new home that isn't green healthier

QUESTION:

Hi,

After reading your great book and using it to completely detoxify our current home, we now have found ourselves in a position where we will have to move. :(

We have found a home deal that is really too good to pass up financially, whereby we would purchase a brand new built home. Unfortunately the most this company can offer as to nontoxicity is low VOC paint inside. I know about "baking the house" before moving in, but you have typically suggested this with a green home.

Are there additional steps or suggestions for a home that isn't green built? We will request all hardwoods throughout and I know they don't use an adhesive to put them down. I also know they use the blown in cellulose insulation. And I know we will paint it with a zero VOC paint weeks before we move in and before we bake it. But unfortunatley there are some obvious downsides we can't get away from.

First are the vinyl windows with no option of wood or aluminum upgrades (nor would we be able to do this on our own until waaay down the road.) Second, they use some sort of PEX piping for the water which is supposed to be a softer type plastic. They claim less leaching than copper but I feel worried. We can't afford to replace all the piping but my husband suggsted mybe we could at least replace the pipes that carry the drinking water with copper for now.

And I am sure there are a multitude of other toxics associated with new home building. So I would truly value your input, are we crazy for going brand new?? Help! What can we do to make it better?

thanks!!!

Plywood

QUESTION:

We are moving into a house that is 22 years old. We are taking out all the carpet and replacing it with prefinished hardwood.

Should we rip out all the plywood (maybe MDF) and glue the hardwood to the concrete or do you think it would have completely out gassed by now and is safe to leave in?

Also, the moisture barriers that I've seen today are in a liqued form that are brushed on the concrete. How do I know if the liquid moisture barrier is safe? Lumber Liquidators uses a brand called Mapei for their adhesives and liqued moisture barrier.

Thanks so much for all your wonderful help!!

Is there safe plywood?

QUESTION:

Hi
I have been using pine to make some things but my wood working friends have suggested that I use plywood instead. They say the plywood is stronger and easier to cut. I am very eco conscious and when I voice my concerns about using plywood one of my frind's reply is - "Well you are not going to eat off of it, what's the big deal?" Please share with me any info that you have about safe plywood. Thanks!!!!

Moving - how safe is the region?

QUESTION:

Hi Debra-

We're moving out of our condo and into a house soon. I've got moderate MCS so I'm looking for the least toxic house I can find in our price range and general area. I live in northern California, in a small city surrounded by farms and agriculture. We may stay in this city or we may move to a nearby city which borders farms, industrial areas, and the larger Sacramento metropolitan area.

My question is: how can I find out about the environmental safety of a particular region?

I've tracked down basic info online, such as air quality for ozone, particulates, etc. But I want to know things such as what the actual dangers are for living near these specific farms or industrial zones. I'm concerned about pesticides and other toxic exposures, but I'm not sure if my concerns are overblown. I've rejected several good houses because they border the agricultural areas, or are right across the river from the industrial zone- because I get nervous about increased toxic exposure from increased proximity to the potential sources. I don't even know if these fields or industrial areas actually pose any real danger (they could be organic farms or low-impact rice processing plants)! So how do I find out? I don't know where to start or whom to ask. Do you have any ideas?

Thanks! Katie in Northern California

Toxicity of nylon in sink spray hoses?

QUESTION:

I'm going to be replacing a kitchen sink faucet, and noticed that many on the market today have a pull out sprayer. This is convenient, but I notice that the spray hose is made from nylon. I am concerned that there may be chemicals that leach out into the water from such a hose.

Interstate Highway and 2" x 4" Metal Studs

QUESTION:

I'm recovering from MCS problems (mostly petro-chemical related) and the neighborhood we live in has too many home owners that use chemical fertilizers and pesticides. So, we are looking for a new home to purchase.

We are contemplating purchasing a home that has a lot of "pluses" for my situation but there are a couple of unkowns that I would like some guidance:

1) It is located 1 mile from an Interstate highway that has moderate traffic. Is 1 mile away too close?? It heads north into Michigan but does not carry heavy traffic like I-94 which is major link between Chicago and Detroit.

2) The house is 8 yrs old and used metal studs throughout the construction of the home. Does anyone have any concerns re: the metal studs and emf?? I plan to take a gauss meter when we see the home. The current heat system is gas/forced air but we may convert to total electic. Would that be a problem? We do have room to put in a geothermal unit.

Your thoughts are appreciated. Thank you.

Basement Flooding

QUESTION:

Debra,
This past year has brought with it an increase in the number of instances of flooding in our basement. We have a typical unfinished basement, and while the flooding used to occur only after unusually heavy rainstorms, we are now noticing small leaks occuring during moderate rainstorms as well. The leaks are in the crack between the wall and the floor. We are planning on building up the soil around our house in the spring to help the water drain away from the foundation, but would like to fix the leaks as well. The problem is beginning to drive me crazy as I'm getting tired of trying to keep the basement dry. I want to fix the leaks in the least toxic way possible (strong fumes give me migraines) but don't know where to begin. Any ideas?

Non-toxic alternative to silicon spray?

QUESTION:

Is there a non-toxic alternative to the silicon spray builders use that is not harmful to vinyl window frames?

I had the unfortunate experience of a window repairman using silicon spray on the difficult-to-raise vinyl window frame in my bedroom, to make it slide easier. I thought the smell (and my reaction) would dissipate quickly. Wrong! My bedroom continued to smell like an auto repair garage.

I tried to wash the spray off in every place I could reach. That didn't help much. Then I rubbed the frame down with orange oil. Helped a bit, but the silicon spray smell quickly returned. Now I've used peppemint oil repeatedly on the frame and into the corners with an eye dropper. After two weeks, it seems to helping.

I think the toxic smell has almost gone, but the repair people are coming back to replace the sash and I need to have an alternative to the silicon spray for them to use. It needs to be something with the slipperyness of silcon spray. I've tried olive oil, but without much success. They said not to use WD40 which leads me to guess that anything with petrochemicals would be harmful to the vinyl. In any event, I wouldn't be able to tolerate something with petrochemicals.

Any ideas would be greatly appreciated.

Thank you.

Spray Foam Insulation

QUESTION:

Hello Debra,

I am a residential architect in the midwest specializing in sustainable design and have been recently introduced to your site and blog by one of our future clients. Together, we are hoping to build a new Green home for them that will be as non-toxic as possible given my clients family's health concerns.

In our office we have been specifying a low-density spray foam insulation that would be installed in the wall and rafter cavities called Icynene. There are many other products on the market in this category but after doing research, including some actual product testing ourselves, we have landed on this as the spray foam insulation of choice.

The manufaturer actually touts the healthy aspects of their product and its low toxicity as being one of its strong suits. We have, in fact, been told by manufacturer's reps that once cured the product is so inert it can actually be eaten without adverse affect! We have passed on that particular test, however.

What is your, or your reader's, experiences with this product and its toxicity levels?

I hate to get rid of it, since it's a beauty (and what a waste!) But I and my 5 year-olds like to take baths. I looked into refinishing (encapsulation) and all the chemicals used in that seem pretty nasty. The companies say that once they refinish, it is perfectly safe. What do you think?

non-toxic stucco products

QUESTION:

Hi Debra,

I've recently discovered that I am sensitive to many different chemicals as well as preservatives in food. I discovered your site while checking on the kitchen cabinets I just ordered from Kraftmaid--all plywood construction.

We are in the process of building a tire bale house in the mountains of Colorado and, when finished, will become a thermal mass. No, the tire bales do not outgas since they are all well used tires. (keeps the mout of the landfill...) The tire bales are actually covered in (shot-creted) concrete and form the structural integrity of the house. The walls are about 6 feet thick. I can overcome concrete dust by nasal washing. The floors are polished concrete as part of the thermal mass.

As we are planning the interior stucco, dry wall, and paint I am wondering which of these products I should be looking at to keep down my reactions. We mostly choose products based on greatest energy efficiency. We've looked carefully at Sto stucco products and are using them for the exterior. We're looking at another interior stucco product with fibers in it that has to be applied while wearing protection (mask & goggles), and I am wondering if the fibers will still be "in the air" once we are finished applying it to the tire bale walls, and how long those fibers will be in the air. I know how "dusty" dry wall can be, and I don't plan to be in the house while that activity is going on. But, I'm wondering if there is an alternative to regular dry wall. I think I can find some recommendations on your blog on paint.

I would appreciate any references or research on stucco and dry wall products.

Thanks for all the good info.

Flooring: Least Expensive and Least Toxic

QUESTION:

Debra~

We are trying to decide on the least expensive flooring that is also the least toxic. We've looked through all of the information on flooring you have here and have 4 questions:

First, would the aluminum oxide finish on the Lumber Liquidators cork tiles dust into the air at all with friction (walking, sliding furniture)? What about with the acrylic finish on the wood parquet tiles from Lowe's? Does being baked-on mean that the particles of these finishing chemicals are completely unable to become airborne and thus inhaled?

Second, do you or any of your readers know if the Lumber Liquidators cork tiles are made with no or low-toxicity materials? It seems that not all cork flooring is alike, and this does seem quite inexpensive ($.99/sq. ft.) for cork (since it usually is in the $8-$10 range or more). Has anyone used this particular cork flooring from Lumber Liquidators?

Third, has anyone here used the "utility" unfinished wood flooring from Lumber Liquidators, also at $.99/sq. ft.? Can this flooring be used in any room? What about leaving it unfinished?

Fourth, would the yellow woodworker's glue found at most hardware stores work for putting down wood or cork tiles?

Thank you so much, Debra!

Crawlspace and Mold

QUESTION:

I have been reading your information on mold and the remediation you have done to your home.

We purchased our first house two years ago and it has been a nightmare. Many of the problems we are having are a result of a very damp and narrow crawl space. When we first moved in, we had special vents installed and put down a plastic vapor barrier. We still have very high humidity in our home which has ruined our flooring and our 5 year old roof.

The leaking roof ruined our walls and ceilings before we caught it. I have seen small amounts of mold in many different areas of our house. We are having the roof redone and the flooring replaced. There is no way we can afford mold remediation, unless we do it ourselves.

But our biggest problem is resolving our crawlspace issue. We have looked into a company that uses something called "clean space" technology. The idea is that completely sealing the crawl space will eliminate the moisture.

I have been researching for hours and the studies seem pretty convicing, but I wonder what we would be sealing in. Chemicals? Bacteria? Radon? I am also concerned that drying up the mold and disturbing the crawl space will bring even more pollution into our home (our duct work is in the crawl space).

Does anyone out there have any experience with this? We live in MI if this helps at all.

Baking Out Toxic Flooring Adhesive

QUESTION:

Dear Debra,

Thanks to you and AFM for your response to our question regarding the offgassing of a lift chair. We have ordered the chair and will be spraying it with AFM SafeCoat Lock Out.

Our next question regards new subflooring that was just put down. We used AdvanTech subflooring per some information we found here and on the Green Guide. However, the contractor used DAP SubFloor & Deck adhesive and OSI Subfloor Adhesive (we didn't realize adhesive would be needed at all, otherwise we would have provided a low-VOC product for the contractor to use).

The toxic smell throughout the house is extremely strong. We are familiar with the "bake out" procedure you have outlined here. Our question, though, is when to do the bake out. We are going to have parquet wood squares installed and other work done, but should we bake out the house before the flooring is put down over the subfloor--or after all the work is completed?

Of course, we are approving every product the contractor uses after this to make sure only zero or low-VOC products are used. This is quite a job, since most contractors just really are not familiar with "no or low-toxicity" building products.

Thank you for the wealth of information you provide, Debra!

Particle/Press Board: Will it fully out gas and become safe?

QUESTION:

hi,

we're remodeling my house, and my husband put some "sound board" on the studs under the dry wall to help with sound reduction. this "sound board" smells HORRIFFIC! it seems very similar to particle/press board. we're hoping that placing the dry wall over it, would essentially seal it, so the smell/toxicity cannot come out. however, not sure if that theory will work. or, are considering getting rid of the sound board all together.

if, in fact, this sound board is similar in composition to press board/particle board....do these types of materials EVENTUALLY FULLY OUTGAS? or is this something that does not, and needs to be 'sealed' with some sort of sealant?

knowing the answer to that question, would help us to determine how to proceed with this project.

and real quick, on the topic of press board: if i have a press board dresser from ikea...will this eventually outgas? (I've had these drawers for about 3-4 years..and my it still stinks!) my clothes left in it, wreak of the formaldehyde (ick!). since i wear primarily 100% cotton, are my natural fabrics absorbing the formaldehyde from the drawers??!! :O

would appreciate your thoughts..
thank you.

making my own wool insulation

QUESTION:

I'm wondering if you know how to make my own wool insulation? I have access to a lot of free wool and a small living structure to insulate. I know the basics of processing wool but don't know how to make the actual insulation batts.

cork flooring

QUESTION:

What can you tell me about cork flooring? Is it all safe? We are looking at getting prefinished cork. I'm not sure if this is covered in your book. I just purchased it a few days ago and will get it soon, but we need to make a decision quickly because I just tore all of our icky carpet out of the bedroom today! Thank you.

Choosing Between Natural Insulations

QUESTION:

I need to insulate my attic--drafty old home with zero insulation. Can only afford to do attic. Choosing between Ultratouch Cotton or Biobased Vegetable.

I am concerned about Ultratouch because someone told me that it has boric acid in it to make it flame retardant and that can be bothersome and I am concerned that Biobased because I read it is a two-part soybean based polyurethane. (Yikes that sounds smelly!)

Please advise if possible,

Stabilized Cellulose Insulation

QUESTION:

Hi there,

A friend recently contacted me and told me she had purchased stabilized cellulose insulation for her (existing) Florida home and has seen a tremendous difference in her electric bill since. The websites I have looked at claim it is a totally natural, safe material, but don't give much concrete information beyond that. I was wondering if you or any readers had any experience with it's safety as compared to fiberglass insulation.

Thanks in advance for any information.

Latex Foam Sealant

QUESTION:

I am a project management consultant, and have been using "Latex Foam Sealants" for specific applications for the past 2 years, for its many advantages over standard foam products.
However, my current client has expressed a concern over the product after it has occured and wishes to know if there is any health/environmental issue of the product;
a) after it has cured. ie. will it give off any harmful gases/odors?.
b) Is there any issue next to hot water heating pipes?
c) will it break down over time? (this installation is NOT exposed to UV)

Products are
DAPtex® Latex Insulating Foam Sealant
Website http://www.dap.com/product_details.aspx?product_id=11

and

Touch-n-foam
http://www.touch-n-foam.com/foamlatex.htm

Both appear and behave very similar (I would almost hazard a guess made in the same factory).

Safe Caulk and Preprimed Wood

QUESTION:

1) I’m needing to do some caulking on the outside of my house, but near my bedroom window so I want to use a safe one. You mention, in Home Safe Home, there is a safe brand. Could you disclose that to me? I’d appreciate it.

2) The contractor wants to use a pre-primed wood instead of priming the wood and then painting. My fear would that this pre-primed wood will be treated beforehand. Have you had experience with something like this?

I hope to hear from you soon. It’s always scary to do something to my house for fear of reacting to whatever it is. Thanks.

Safe tile grout and backerboard

QUESTION:

Thanks to all your tips, my wife is really feeling much better with her MCS. In fact, we're now carefully considering putting a tile floor where the carpet used to be in the bathroom adjacent to her bedroom. Using your recommendations we have found safe tile adhesives and grout sealers but we can't find anything about safe grouts.

Can you recommend any products for a chemically safe grout and are there any problems to watch out for in the cement board underlayment materials?

Green Bathtubs

QUESTION:

I am looking for an airjet tub that would be safe. One company [name deleted] said that their urethane tubs are the only green product around. My HVAC guy says that 100% acrylic tubs are inert. However, as far as I can see, the acrylic tubs have a fiberglass and resin shell which is where the problem mostly lies. Any info?

Also, do you know how to construct a tiled bathtub where the bathtub itself is made of tile?

Safety of ACQ Pressure-Treated Wood

QUESTION:

I live in Orford Qc where there is a conservation national parc, a very delicate ecosystem. Unfortunately , it is a very beautiful mountain also and a promotor is now on is way of exchanging the land for another to built around 2000 condos and new golf courses. The builders have already constructed many sidewalks and belvedere in the parc with ACQ wood they say, to me it smells like CCA wood. Suppose for the moment it is ACQ, is it safe for a prolong exposition to wild life and for the drinking water of the community?

I am concerned and I asked the promotor during the BAPE hearings yesterday. He said that it is safe and the park authorities also. I am not conviced, since he is using vinyl a lot in other constructions.

Do you have any comments on the safety of ACQ?

Need Help With Kitchen Reno!

QUESTION:

I find myself overwhelmed with choices for an eco kitchen reno. It seems that either solid wood cabinetry or cabinet boxes made of strawboard with solid wood
fronts are the only eco options. I've tried re-covering used cabinets from the paper, but they are always in really bad shape.

Further, are granite or soapstone the best environmental options for countertops, and doesn't it depend on the granite's source?

My kitchen is falling apart and I'm afraid to take one step forward!

Thanks for any help you can offer, and I really love your newsletter.
