Fiberglas™ FLEXWRAP®

Description

Owens Corning® Fiberglas™ FlexWrap® is a flexible, high-performance fiberglass insulation solution designed for wrapping pipes, tanks, ducts, and other irregular-shaped surfaces. Engineered with a thermosetting resin-bonded fiberglass blanket, FlexWrap® provides excellent thermal insulation and durability, suitable for temperatures up to 850°F (454°C). Its continuous blanket design reduces efficiency losses from strip delamination, making it ideal for both hot and cold service applications in industrial and commercial environments. The ASJ Max and FRK facings offer enhanced protection and eliminate the need for additional jacketing in most interior applications.
