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