Product Description
Insulation sheet is NBR/PVC closed cell, flexible elastomeric foam insulation. It is used to conserve energy and prevent condensation on large pipes, ducts, vessels, tanks and equipment. It is environment friendly as free of CFCs, formaldehyde and fibers.
Insulation sheet is used to retard heat gain and prevent condensation or frost formation on below-ambient applications, including utility and industrial process equipment, tanks, vessels, ducts and large diameter pipes in refrigeration line, HVAC systems. It can be used with heat tracing tapes. Insulation sheet also retards heat loss from medium hot surface.
Insulation sheet is flexible even at low temperatures. It is durable and safe to handle, and lightweight for an efficient installation. Insulation sheet can be installed onto large OD round surfaces or flat surfaces. For round surfaces of piping or ductwork, the sheet should be wrapped around the pipe and sealed at the longitudinal seam with an approved contact adhesive.
Our insulation sheet is available in a range of wall thickness from 1/8” to 1-1/4”. It is 25/50 rated (flame spread rating of 25 or less and smoke development rating of 50 or less) according to ASTM E84 standard (Surface Burning Characteristics of Building Materials). Insulation sheet is available in color of Black, Green, Blue and Red.
