Tested Roof Assemblies - Verified Results

Introduced to the market nearly 30 years ago, DensDeck® Roof Boards are the first gypsum roof boards tested to contribute to Sound Transmission Class (STC) ratings of up to 61 and Outdoor Indoor Transmission Class (OITC) ratings of up to 49 in roofing assemblies for commercial framed construction*. These high levels of sound attenuation are especially important as new code and building programs call for sound mitigation in wall and roof-ceiling assemblies.
