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. Possible condensation is therefore always avoided within the usual range of temperatures for ALUTHERMO QUATTRO.

  • 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.
