CrimpWrap ASJ fiberglass pipe & tank insulation wrap

CertainTeed CrimpWrap is a flexible fiberglass pipe and tank wrap designed to insulate large-diameter pipes and vessels. The ASJ-faced blanket helps reduce heat loss/gain while providing a clean, durable jacketed surface for commercial and industrial applications.


Key Features:

  • Efficient Thermal Insulation: Helps control heat loss or gain and provides protection from hot surfaces during system operation
  • Flexible Yet Supportive: Combines rigid fiberglass board-like thermal/compressive performance with flexibility to wrap vessels and large diameter pipes
  • Economical for Large Diameters: More cost-effective than molded pipe insulation when wrapping larger pipe sizes
  • Continuous Blanket Construction: Helps reduce the risk of strip delamination common with traditional tank-wrap styles
  • Jobsite-Ready Facing: ASJ (All-Service Jacket) facing provides a clean exterior surface suitable for many mechanical insulation applications
