Completely resistant to mold, mildew, rot and bacterial growth.
Its non-directional fiber structure and higher density give it better dimensional stability--it won't sag inside walls.
Easy to Cut and Install for Optimal Fit: allows you to accurately trim the insulation to the wall or ceiling cavity--and get an optimal fit around electrical boxes, wiring, plumbing and ductwork. The result is better R-value and maximum sound absorption.
Fire Resistant: Its unique composition won't burn or release toxic gases or smoke when exposed to high heat. Roxul offers a barrier that can delay the spread of fire and provide your family with precious extra minutes to escape. And it can withstand temperatures of up to 2150°F (1177°C)--well above heat levels of typical house fires.
