Product Details
This superior closed cell insulation is designed to retard heat flow and prevent condensation when properly installed. Insul-Lock® Seam-Seal pipe insulation features pre-slit design with a factory-applied specially formulated bonding adhesive on both seam surfaces and comes with built-in release liners for easy installation. It is ideal for applications such as refrigerant lines, cold water plumbing, roof drains, and chilled water systems, and is made from a UV-resistant elastomeric blend. For moderate UV exposure, no additional protective coating is needed, but for severe UV exposure or where optimum performance is required, 374 protective coating or approved jacketing or cladding should be used. The insulation complies with multiple specifications, including ASTM C 534 Type 1 (tubing), Grade 1, ASTM D 1056-00-2C1, New York City MEA 186-86-M Vol. IV, USDA requirements, and UL 94-5V flammability classification (recognition no. E300774). It has been tested according to ASTM E 84 1-1/2" 25/50, meeting the requirements of CAN/ULC S102-03, and has FMRC approval under chapter 14 for pipe insulation. Additionally, it meets requirements of NFPA 90A sect. 2.3.3 for supplementary materials for air distribution systems and ASTM C 411 for hot surface performance of high-temperature thermal insulation. It also meets UL 181 sections 11.0 and 16.0 for mold growth and air erosion. The product is sold in a package quantity of 7, priced each.
