Do SIPs contain Formaldehyde?
The answer to this question is technically yes, realistically no. This is the case because the amount of formaldehyde emitted by the oriented strand board (OSB) used in SIPs is less than 0.1 PPM (parts per million). This is well below levels established as acceptable by the U. S. Department of Housing and Urban Development, (HUD). In fact, the HUD Standard now in effect exempts OSB that is produced with these phenolic type adhesives. Large chamber testing demonstrated that emissions of formaldehyde from OSB is less than would be encountered in the normal atmospheric levels of an urban environment. Testing done by APA – The Engineered Wood Association, has been extensive and conclusive. With their permission, a report that provides more detail on this subject has been reprinted and is available from the APA or SIPA offices. The rigid foam cores and the structural water base adhesives used in the panel manufacturing process have no formaldehyde content and are inert plastics prior to lea
