Stainless Floor & Tunnel Shield is a high temperature solution for not only controlling heat, but sound as well. The new stainless steel surface, backed with a high-temp resistant glass fiber, is able to handle higher temperatures but also has micro perforations to control noise as well. It's poilshed dimpled surface reflects heat while the perforations allow sounds to be absorbed. Cuts easily with tin snips and aggressive adhesive backing makes installation easy.
