Specialists in Lacquering Aluminium Coils

insulax® BT

bobina-alucoat-clopp-bebidasinsulax® BT is the designation of ALUCOAT for the lacquered foil intended to be used for the production of insulation structures for building (roofs, chimneys, among others). insulax® BT is the adequate product to be laminated with bitumen for water proofing in roofs. We can supply this range of product with our new series of coating and qualities of lacquer that provides an excellent resistant to humidity, gas and U.V. light. It can be laminated to other materials in order to form very high performance insulation and barrier products.  

Range of products

  • There is a new version of insulax® BT for external applications. This new version offers a high-value, high-perfomance with special pigments highly reflective to sunlight. Absorb much less heat than conventional insulation systems, thus resulting in a reduction of energy consumption of the building. There are two kinds of lacquer for this application:
    • insulax® BT HQPE
    • insulax® BT PVdF
  • These twho white lacquers fulfill the USA Normatives “Tittle 24 of the California Code of Regulations” about emissivity and reflectance.
  • Also for all range of products an alternative with a pre-treatment coating patented by ALUCOAT that improves the corrosion resistance and the adherence of the lacquer over the aluminium surface.

ALUCOAT supplies its product insulax® BT in reels of wide until 1.600 mm, with core of steel or carton up to 500 mm and maximum weight of 6 tonnes.

insulax® BT is particularly suitable for bituminous roofing insulation (roofing felt).
