Does TimberSIL® require local or state building code or agency approval?
Because TimberSIL® is non-toxic, natural wood no special approvals are required for most common uses. However, when used in applications that specifically require Class A Fire Ratings or barrier free certifications, it is best to confirm acceptance with local officials. Most documentation required by state and county agencies can be obtained directly from our website under our Tech Specs page. Each of the documents are in PDF format that are can be downloaded and printed.
