Closed cell, physically crosslinked polyolefin foam insulation
with ultra-tough foil facing to prevent
mechanical damage in high-risk areas


Thermobreak® No–Clad is designed as a cost-effective alternative to cladding of pipe and duct insulation to prevent mechanical damage. It differs from standard Thermobreak® in that the aluminium foil is puncture resistant multilayer consisting of:

  • A salt-water resistant, UV and weather durable coating.
  • The aluminium foil is reinforced with an ultra-tough, close weave scrim.
  • The flexible closed cell physically crosslinked polyolefin foam underneath allows for distribution of impact force so inhibiting mechanical damage to the insulation.

Although designed to be resistant to mechanical damage, Thermobreak® No–Clad has been designed for easy Fabrication using sharp knives.
