Overview:

K-FLEX® INSUL-LOCK® DS (DoubleSeal) is a flexible closed-cell elastomeric insulation tube product used to conserve energy and prevent condensation on piping applications. It is pre-slit with a factory-applied pressure sensitive modified-acrylic adhesive with scrim reinforcement on the seam surface and a flexible PVC overlap tape with acrylic adhesive for doubled seam security. The system reduces installation time and costs, and ensures a strong, durable seal.

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 in applications within a -40°F to +220°F temperature range.

K-FLEX® INSUL-LOCK® DS is widely used for its cold weather flexibility, durable skin surface, exacting manufacturing tolerances and lasting performance. It is available in 6’ lengths in wall thicknesses ranging from 3/8”* to 2”.

K-FLEX® INSUL-LOCK® DS 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® DS 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.
