Product Description

VIFLEX Rubber foam insulation are closed cell elastomeric foam structure whose non-porous composition offers high thermal efficiency as well as protection from imminent condensation problems. Due to their dimensional stability, they reduce friction and reduce installation time significantly. The product's closed-cell structure creates exceptional thermal properties (k-value of 0.245 at 75F and wvt of 0.03 perm-in) that protect against moisture penetration and heat loss or gain within a -297F to +220F temperature range.
