Thin insulation
of the roof from the interior
with or without breather membrane

Insulation of the roof from the interior with or without a breather membrane

Even if the roof is in good condition and must still be insulated, Aluthermo® allows an easy roof insulation from the inside without losing space. What’s more, Aluthermo® thin roof insulation can be installed without interruption or gaps, and ensures good air-tightness.

As the thin reflective insulation Aluthermo® is rolled out directly under the rafter, its installation is easy and quick and avoids an increase of the rafter thickness if the space is too small for a conventional insulation. Furthermore Aluthermo®, installed form the interior, also serves as a vapor barrier.

A good insulation without breather membrane

Whether with or without a breather membrane, with Aluthermo® the insulation without a breather membrane is possible.

Exterior humidity is not an issue for Aluthermo®, compared to most of the other insulation materials, and can therefore be placed without a breather membrane, or with a breather membrane that has been ripped over the years. There’s no easier and more efficient way.

Aluthermo® can easily be cut with a craft knife or with Aluthermo® scissors. The installation is very easy as the different components don’t cause any irritations of the skin or the respiratory tracts.

By using Aluthermo®, you win space in the attic. Aluthermo® provides protection against solar radiation to improve your overall comfort in summer. Furthermore you don’t have to remove the roof tiles to install a breather membrane. With Aluthermo® there is no necessity for a ventilated layer when fitted retrospectively.
With Aluthermo® insulation without breather membrane is finally possible!
