How does Optima®  work ?

OPTIMA is composed of the following compressible successive layers:

  1. A film of pure 30 microns thick aluminium, treated against oxidation
  2. A layer of bubbles of dry air enclosed in polyethylene
  3. A moisture-proof polyester fiber
  4. of dry air enclosed in polyethylene
  5. A layer of bubbles of dry air enclosed in polyethylene
  6. A film of pure 30 microns thick aluminium, treated against oxidation

aluthermo optima

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.

(*) 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.
