The range of Aluthermo® insulation systems is divided into two main families:
1) Aluthermo® 7mm, 14mm and 21mm :
Aluthermo® is an insulating material that works by reflection and consists of two layers separated by a honeycomb structure of air bubbles enclosed in a fireproofed (fire-retardant) polyethylene film, which is covered on both sides by a 30-micron thick foil of pure aluminium that has been polished and treated against oxidation. |
|
The obtained complex is semi-rigid and consists of the following successive layers:
A. 99% pure aluminium film, 30 microns thick
B. Fire-retardant polyethylene film containing bubbles of dry and stable air
C. Fire-retardant polyethylene film containing bubbles of dry and stable air
D. 99% pure aluminium film, 30 microns thick
The air enclosed in the bubble films is dry and stable. Any condensation is therefore prevented within the temperature ranges recommended for each thickness of Aluthermo® (see Applications and technical characteristics).

2) L’Aluthermo Quattro®
Aluthermo Quattro® is the first thin, multi-reflector, multi-layer insulation system with all surfaces fully thermally welded together.
Aluthermo Quattro® consists of two 30-micron thick outer layers of polished and anti oxidation treated pure aluminium separated by two honeycombed layers of air bubbles enclosed inside a fire-retardant polyethylene film, together with two extra layers of pure aluminium foil and a fire-retardant and water-repellent polyethylene foam.
Aluthermo Quattro® provides an almost impenetrable barrier against infrared radiation in both summer and winter. |
The air inside the bubble films and in the polyethylene foam is dry and stable. Any condensation is therefore prevented within the normal temperature ranges for Aluthermo Quattro® (see Applications and technical characteristics).

|
The obtained complex is semi-rigid and consists of the following successive layers:
-
A layer of pure aluminium foil, 30 microns thick, treated against oxidation
-
A layer of dry air bubbles enclosed in fire-retardant polyethylene
-
A layer of pure aluminium foil treated against oxidation
-
A fire-retardant and water-repellent polyethylene foam
-
A layer of pure aluminium foil treated against oxidation
-
A layer of dry air bubbles enclosed in fire-retardant polyethylene
-
A layer of pure aluminium foil, 30 microns thick, treated against oxidation |

To make installation easier, all the bonding surfaces inside both Aluthermo® and Aluthermo Quattro® are thermally welded together.
