ALUTHERMO QUATTRO

An ideal «all in one» solution as it acts as an insulation material, vapour barrier and roof membrane. An ultra-thin, multi-reflective and with 4 layers of aluminium multi-layer insulation material which is thermally-welded across all its surfaces.

HOW DOES IT WORK?

QUATTRO is a semi-rigid complex composed of the following successive layers:

  1. A film of pure aluminium, 30 microns thick, treated against oxidation
  2. A layer of bubbles of dry air enclosed in self-extinguishing polyethylene
  3. A film of pure aluminium treated against oxidation
  4. A foam of fire-retarding and waterproofed polyethylene
  5. A film of pure aluminium treated against oxidation
  6. A layer of bubbles of dry air enclosed in self-extinguishing polyethylene
  7. A film of pure aluminium, 30 microns thick, treated against oxidation

The air trapped in the bubble film and polyethylene foam is dry and stable.

  • Multi-reflective and multi-layer
  • Easy to install as it is thermally-welded across its entire surface
  • Durable as pure aluminium
  • Fire protection class Bs1d0
  • Roof membrane, insulation material and vapour barrier all in one
  • No shrinkage and rotproof
  • 10-year warranty in association with Allianz Insurances

(*) Performance data only valid for the installation between 2 air gaps without direct contact (see installation instructions of the product).
(**) Thermal performance measured by the Eliosys laboratory, comparing the energy consumption of a structure insulated once with Aluthermo and once with 200 mm of mineral wool (λ 0.040 W/m.K.)
In the absence of consensus on the standard, this result is not considered in the calculation of the EPC or the obtaining of a subsidy. See the Eliosys test report.
