K-Flex 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 75 deg F and wvt of 0.03 perm-in) that protect against moisture penetration and heat loss or gain within a -297 to 220 deg F 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.
