The two brands of fiberglass-faced gypsum panels that I could find data for state that they are “low VOC” products. I located 1 MSDS, and it didn’t give emissions data, but the difference between “low” and “no” VOC is often critical for chemical sensitivities.

<div class=""><br class="">
</div>
<div class="">I agree with Chris, that introducing new fiberglass seems risky for someone with chemical sensitivities. I’d suggest seeing if there is a way to pin down what she is reacting to. 15-year-old plywood, OSB, and drywall have given up the majority
of their gases. They might still be causing the problem, but might there be another source for the problem? Ventilation ducts? Something in the ceiling/roof? Gases coming up through the soil or floor? </div>

<div class="">I work with shellac a lot, and it can be a superb sealer. The big question mark is the solvent. Denatured alcohol is normally used, and the “denatured” part is the addition of poison to the mix. Usually methanol is added, but many other toxic
and cheap chemicals are frequently part of the formula, and often not fully listed, since they are proprietary and our disclosure laws are very weak. So-called citrus solvents may or may not be safer. Unless you can be very sure about the solvents used,
I would be nervous about shellac products. Clay paints from a reputable company seem like a safer way to go. </div>

<p class="">Hi Tony,</p>
<p class="">If she is chemically sensitive, I wouldn't recommend using fiberglass.</p>
<p class="">AFM Safecoat makes a sealant for holding back VOCs from materials like plywood:
<a class="m_8835780278506792807moz-txt-link-freetext" href="http://www.afmsafecoat.com/products/stains-sealers/safecoat-safe-seal" target="_blank">
http://www.afmsafecoat.com/<wbr class="">products/stains-sealers/<wbr class="">safecoat-safe-seal</a>. We've used it for chemically sensitive clients where we can't get rid of the material and it seems to work well.</p>
<p class="">I haven't put clay paint directly over the AFM sealant before, but the companies we use for clay or lime paints (Kreidezeit and Auro) make primers that are full disclosure ingredients and would allow their paints to be used.</p>

<div class="">I am probably ignoring list etiquette by not sifting through the archives, but I have a workmate who is rapidly trying to remodel a space for his daughter who is chemically sensitive and reacting to her current living space. He was directed toward
clay paints, though since part of the space is enclosed with 10-15 year old OSB and plywood, I suggested he might also consider sealing that and the 5/8'" drywall with fiberglass inside before covering it.</div>
<div class=""><br class="">
</div>
<div class="">We are within driving range of retailers like Organic Grace in Garberville where both paints and sealers are available, though budget is a concern. Simple clay paint recipes might be useful.</div>
<div class=""><br class="">
</div>
<div class="">Also he mentioned something I think he was told at a Kelly Moore shop where they have an alcohol-based sealer like a shellac that off-gasses heavily for a very short period of time, but is then safe.</div>
<div class=""><br class="">
</div>
<div class="">Any input?</div>
<div class="">Thanks in advance, and hi, howdy and hugs all round.</div>
