ALUTHERMO Optima

A reflective insulation material made thicker to comply with European standards. Mainly used on roofs or as a vapour barrier on walls. EPC & LABC certified.

HOW DOES IT WORK?

OPTIMA is composed of the following successive layers:

A film of pure 30 microns thick aluminium, treated against oxidation
A layer of bubbles of dry air enclosed in polyethylene
A moisture-proof polyester fiber
A layer of bubbles of dry air enclosed in polyethylene
A film of pure 30 microns thick aluminium, treated against oxidation

The aluminium sheets reflect thermal radiation summer and winter, while the polyester wadding core and the dry, stable air trapped in the bubble film effectively slow the transfer of energy by conduction.
This thin, high-performance insulation material also offers an impermeable barrier to moisture and is vapour proof.

Advantages

EPC & LABC certified
Insulation and vapour barrier all in one
Easy to install as it is welded across its entire surface
Multi-reflective and multi-layer with a reinforced thermal and acoustic performance
Reduces thermal bridges
Durable as pure aluminium
10-year warranty in association with Allianz Assurances

(*) 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.
