CrimpWrap™ provides the thermal and compressible properties of rigid insulation board in a unique flexible blanket of variably oriented glass fibers firmly bonded together with a thermosetting resin. Available with either Foil Scrim (FSK) or white ASJ vapor retarder facings, CrimpWrap™can control heat loss or gain on large diameter pipping and equipment more economically than molded insulation. Insulating vessels and pipes with service temperatures from 35oF  to 850oF (2oC to 454oC), CrimpWrap™also provides hot surface protection for personnel during system operation.


  • Economical - CrimpWrap is more economical than molded pipe insulation when used to wrap large diameter pipe
  • Thermal Performance - Helps control heat loss or gain and provides protection from a hot surface during system operation
  • Rigid Fiber Glass Board Qualities - Thermal and compressible properties of rigid fiber glass board, yet flexible enough to wrap vessels and large diameter pipes
  • Helps Eliminate Strip Delamination - The continuous fiber glass blanket construction eliminates the potential for strip delamination common in traditional tank wrap type insulation
