Walls are responsible for about 20% of heat loss in a house. Insulating walls from the exterior enables them to accumulate and retain heat. In summer, Aluthermo® also protects the house from solar radiation.


Fasten a framework of timbers measuring 30 mm thick by 5 cm wide to the wall to be insulated. Unroll the Aluthermo® insulation horizontally over this framework, forming an overlap of at least 5 cm between successive strips.

Seal the overlaps and joins with the special aluminium adhesive tape supplied by Aluthermo.

Provisionally fasten the Aluthermo® insulation by stapling it to this wooden framework. The vertical timbers of the framework must be spaced at approximately 60 cm apart. The perimeter timbers must be positioned flush with the horizontal and vertical limits of the surface to be insulated.

This framework establishes a stable air gap between the Aluthermo® insulation and the insulated wall.

Then fasten the counter-battens to the framework for the final metal or timber cladding.

Our product recommendation:

I opt for QUATTRO for maximum space saving

quatro-1QUATTRO – 10mm
An ideal “all in one” solution as it acts as an insulation material, vapour barrier and roof membrane. An ultra-thin, multi-reflective and with 4 layers of aluminium multi-layer insulation material which is thermally-welded across all its surfaces.


  • Minimum thickness with maximum insulation effect
  • Semi-rigid, does not collapse
  • Does not sag over time
