VAPREFLEX®
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.
HOW DOES IT WORK?
The obtained complex is semi-rigid and consists of the following successive layers:
- A film of pure aluminium, 12 microns thick, treated against oxidation
- A layer of bubbles of dry air enclosed in self-extinguishing polyethylene
- A layer of bubbles of dry air enclosed in self-extinguishing polyethylene
- A film of pure aluminium, 12 microns thick, treated against oxidation
The air trapped in the bubble film and polyethylene foam is dry and stable. Possible condensation is therefore always avoided within the usual range of temperatures for ALUTHERMO®.
