I am considering using your product in a residence. It was brought to my attention that the warmboard product contains Formaldehyde. 1. Can you please clarify how much Formaldehyde is present in a house when the product is used in a floor? 2. Also, is there any difference in the amount of Formaldehyde in your products, specifically the ¾” or 1 1/8” thick products? 3. Can you please clarify what the testing conditions were for determing the “trace levels of Formaldehyde”.
Hello. And thanks for your question.
Formaldehyde remains a hot topic for many. It is important to note that formaldehyde is a naturally occurring chemical and is found in wood. So basically ALL wood products contain some level of formaldehyde, Warmboard included. This is natural and not hazardous to your health.
Many manufactured wood products do contain powerful resins and adhesives. Typically, these products have contained urea-based resins, which do increase formaldehyde exposure. (you may recall the dust up with a certain hardwood company a couple years back – the urea resin was the issue in that instance). Warmboard however uses phenol resins, which do not contribute to formaldehyde concentrations. Both our Warmboard-R and -S panels use the same phelonic-based adhesives, so there is no gain in using that type of adhesive.
Typical indoor air contains about 10-30ppb of formaldehyde. Warmboard will not have any affect on this number.
Our panels are certified by the APA, and our listing is below their PS-1 threshold.
