CLIMCOVER CR Alu2 is designed to provide thermal and acoustic insulation for circular ductwork, tanks and large diameter pipes.

The CLIMCOVER CR ALU2 range is a dense glass wool insulation with higher mechanical performance, ideal for use in applications where the resistance to compression is needed. It is designed to be installed on the outside of circular ducts to provide thermal and acoustic performance, fulfilling the requirements of BS 5970 with a neat and professional finish.

Suitable for applications inside or outside a building (with appropriate cladding), CLIMCOVER CR Alu2 offers consistent thickness recovery and a uniform shape with no soft edges.

The range is designed to withstand site conditions, storage and transportation. A factory applied aluminium foil facing provides an inherent vapour barrier.

Key Benefits

  • Thermal performance –The CLIMCOVER CR ALU2 range helps to meet thermal building regulations. It offers significant energy savings by protecting the installation from external thermal variation. 
  • Acoustic performance - Noise levels from ducts can be greatly reduced due to the inherent acoustic properties of CLIMCOVER, improving the comfort of those within the building.
  • Fire Classification – Euroclass A2 fire rating when classified with BS EN 13501-1
  • Higher mechanical performance -  suitable for use in applications:
    • with external coverings.
    • at low levels 
    • where the resistance to compression is needed
  • Ease of install - The range offers longer length rolls which are lightweight and have excellent flexibility and mechanical strength, allowing fast and efficient cutting and fitting.
  • Recycled glass – Manufactured from up to 80% recycled glass.
