Use as insulator for stainless steel liners in masonry chimneys. UL Listed insulation. Size is based on vent diameter.
Required to insulate stainless steel liner to meet UL 1777 when proper clearances to chimney and framing are not available. 1" clearance from SS liner to interior wall of the masonry chimney and 1" clearance from the masonry to the house framing are required in order to meet UL 1777. If you do not have either of these clearances then a 1/2" wrap is required. If these two clearances are available then no insulation is needed. AluFoil Tape and ProMesh required.
