Rockwool ComfortBatt

Rockwool ComfortBatt R22 5.5 in. x 15.25 in. x 47 in. Wood Stud Insulation

COMFORTBATT® is a stone wool insulation product for use in both new residential builds and renovations. This semi-rigid batt has a unique flexible edge designed to compress as the batt is inserted into walls, attics, ceilings and floor frames. The flexible edge springs back, expanding the batt against the frame studs to give a complete fill. ROCKWOOL COMFORTBATT® compensates for normal variations in stud centres caused by distortion or warping. The special flexible characteristic at the insulation edge ensures that the expected R-value is achieved.
