Aluthermo 21mm in 7mm

Thin, multi-reflector insulation composed of two layers of pure aluminium 12-microns thick, polished and treated against oxidation separated by two layers of air bubbles placed in a honeycomb structure and enclosed in a self-extinguishing polyethylene film.

Equivalent thermal resistance: R = 4.873 m².K/W according to the Report issued by the  Liege University Thermodynamics Laboratory, entitled “Radiated heat exchange between  two walls separated by reflective insulation” (“Echanges de chaleur radiatifs entre deux  parois séparées par un isolant réfléchissant”).

The various layers must be thermally welded together over their full surface areas.
Fire protection class: M1
Thickness: 21mm
Weight: +/- 620 gr / m²

aluthermo-21-14-7The obtained complex is semi-rigid and consists of the following successive layers:

A. A film of pure aluminium, 12 microns thick, treated against oxidation
B. A layer of bubbles of dry air enclosed in self-extinguishing polyethylene
C. A layer of bubbles of dry air enclosed in self-extinguishing polyethylene
D. A film of pure aluminium, 12 microns thick, treated against oxidation
