Permalite Insulation and Permalite Recover Board are the most durable. high-quality
expanded-perlite insulation boards available. Perlite. a natural occurring siliceous rock. expands when heated. creating millions of small bubbles that trap air and endow the resultant material with good insulating properties. Both Permalite Insulation and Permalite Recover Board offer economy. thermal
performance. CL and FMRC Class A system approvals and maximum toughness as a substrate for built-up and modified bitumen roofing systems. With over 30 years of proven performance. GAFTEMP Permalite Insulation is a rigid mineral-aggregate insulation
composed of expanded perlite. cellulose fibers. binders. and
waterproofing agents. A minimum of 259C of its composition IS recycled material.
. features a top surface that is specially treated to retain bitumen to ensure a tight bond with the membrane when the board is used as a base
. available in a variety of thicknesses and board sizes
. suitable for protecting foam insulations from hot
asphalt
. provides protective layer over soft
insulations susceptible to traffic damage Permalite Recover Board is a heavy-duty
1/2" thick board composed of expanded perlite. cellulose fibers. binders and waterproofing agents. .
an economical reroofing base that can be installed at a far lower cost than a tear-off .
the standard for insulation applications when your requirements call for reroofing or repairs
. ideal for applications where a tear-off would create unnecessary risks to building operations or materials
Ratings and code
