INSUL-SHEET® is a flexible, closed-cell elastomeric sheet insulation product used to conserve energy and prevent condensation on large pipes, ducts (covers), vessels, tanks and equipment.  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.

An easy-to-clean and uniquely tough protective skin on both sides provides a better surface to resist moisture and dirt.  The double-sided skin can be used with either side facing away from the applied surface, resulting in less waste if one side becomes damaged.

INSUL-SHEET® is available in 36” x 48” sheets or 48" wide rolls up to 2" thickness.  It is non-porous, non-fibrous and resists mold, fungal and bacterial growth.  For added protection, Insul-Sheet® is protected with an EPA-approved antimicrobial agent. 

INSUL-SHEET® is GREENGUARD® certified under the Children and Schools classification, is approved through supervision by the Factory Mutual Research Corporation, and is 25/50-rated when tested to ASTM E 84 standards up to 2" thickness.
