Heat-sealing Foil-Kraft-Scrim Facing lamination with insulation
materials by heating
Product Description
A high grade Foil-Scrim-Kraft Facing with 2-way scrim and 60gsm
Kraft, mainly used as a facing & vapor barrier for glasswool /
rockwool / mineral wool / foam duct wrap insulation, also suitable
for other insulation applications where a general use vapor
retarder is needed. It is also a
good choice for radiant barrier applications because of its low
emissivity.
