K-Flex Insul-Lock® is a flexible, closed cell elastomeric tube insulation product used to conserve energy and prevent condensation on piping applications. 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 in applications within -297 to +220 deg F temperature range. K-Flex Insul-Lock® is widely used for its cold weather flexibility, durable skin surface, exacting manufacturing tolerances and lasting performance. It is available in 6 ft lengths in a range of wall thicknesses ranging from 3/8 to 2 in and is 25/50 rated, according to ASTM E84 standards for surface burning characteristics of building materials, up to 2 in wall thickness. K-Flex Insul-Lock® is non-porous, non-fibrous and resists mold, fungal and bacterial growth. For added protection, it is protected with an EPA approved antimicrobial agent. K-Flex Insul-Lock® is GreenGuard® certified under the children and schools classification and is approved through supervision by the factory Mutual research Corporation.
