Roxul ComfortBatt is stone wool insulation for use in both new residential construction and renovations. This semi-rigid batt has a unique flexible edge designed to compress as the batt is inserted into walls, attics, ceiling and floor frames. The flexible edge springs back, expanding the batt against the frame studs to give a complete fill
. ComfortBatt compensates for normal variations in stud centers caused by distortion or warping. The special flexible characteristic at the insulation edge ensures the expected R-value is achieved
Applications: Specifically engineered for use in exterior walls, cathedral ceilings, attics, basement walls, exposed floors, and heated crawl spaces, for renovations and new construction.
Made of basalt rock and recycled slag (a by-product of steel production that would otherwise go to landfill). Recycled content is minimum 40%.
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.
Water repellent yet vapor permeable: Stone wool is water repellent yet vapor permeable. Roxul insulation does not absorb water or hold moisture. Its unique stone wool orientation is ideal for repelling and draining water away from the exterior walls, industrial pipe, interior walls, or whatever Roxul insulation is protecting. And, since Roxul insulation does not absorb water, it will not sag or lose its shape, and will retain its R-value. So the R-value installed today, will be the same for years to come.
Completely resistant to mold, mildew, rot and bacterial growth.
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.
