Aluthermo Quattro®:
Technical specification
Thin, multi-reflector insulation composed of two 30-micron thick outer layers of polished and antioxidation
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 fireretardant
and water-repellent polyethylene foam.
The obtained complex is semi-rigid and consists of the following successive layers:
1.
A layer of pure aluminium foil, 30 microns thick, treated
against oxidation
2.
A layer of dry air bubbles enclosed in fire-retardant
polyethylene, diameter 10mm, height 4mm
3.
A layer of pure aluminium foil treated against oxidation
4.
A fire-retardant and water-repellent polyethylene foam,
3mm thick
5.
A layer of pure aluminium foil treated against oxidation
6.
A layer of dry air bubbles enclosed in fire-retardant polyethylene, diameter 10mm, height 4mm
7.
A layer of pure aluminium foil, 30 microns thick, treated against oxidation
The various layer must be thermally welded together over their full surface.
