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:
- A film of pure aluminium, 30 microns thick, treated against oxidation
- A layer of bubbles of dry air enclosed in self-extinguishing polyethylene
- A film of pure aluminium treated against oxidation
- A foam of fire-retarding and waterproofed polyethylene
- A film of pure aluminium treated against oxidation
- A layer of bubbles of dry air enclosed in self-extinguishing polyethylene
- 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.
