CLIMCOVER CR Alu2 is a flexible glass mineral wool roll which can be considered for the thermal and acoustic insulation of ductwork, tanks and large diameter pipes. The increased mechanical resistance means it can be considered for use at all levels, inside a building or outside (with a suitable covering). It features a factory applied aluminium foil facing, providing an inherent vapour barrier and a professional finish.

Product Benefits

  • Thermal Performance - Offers energy savings through helping to control temperatures and reduce heat loss or gain.
  • Easy to Install - Lightweight and offers a combination of flexibility and mechanical strength, allowing fast and efficient cutting and fitting.
  • Acoustic Benefits - The fibre structure of glass mineral wool traps sound energy and dissipates it within its thickness, helping to improve the acoustic comfort of those living or working within the building.
  • Fire Classification - Achieves a Euroclass A2-s1,d0 Reaction to Fire classification, according to EN 13501-1.
  • Sustainability - Achieves a BRE Green Guide rating of A+ which can assist in demonstrating environmental performance in your BREEAM assessments. Manufactured from up to 58% recycled glass. For further details visit
