What is ALUTHERMO® insulation ?

ALUTHERMO® is a thin, reflective, multi-layer, flexible insulation material that is thermally-welded across its entire surface, which is made up of several layers of pure aluminium. It may be used on its own or to supplement existing insulation. It traps dry air in its films. It has been used for years in new construction and renovation for its excellent energy-saving results.
