The insulation of the roof is an absolute priority for those who want to save energy. The roof is the principal source of energy loss in a home.

As the thin roof insulation Aluthermo® also works as a roof membrane and vapor barrier, its installation from the exterior, over the rafters, is very easy, requiring only one single operation.

In a renovation situation, simply roll out over the rafters, the issue of air gaps, height or shape of rafters is no longer an issue.

The thin reflective insulation Aluthermo® is very flexible, adapts to all roof shapes, and avoids increase of thickness to the structure. The architecture of the building is not affected which is particularly good for listed buildings as the roof and gutter do not need to be modified.

The strong reflective property of Aluthermo® reflects more than 95% of the solar radiation and improves the ambient temperature by reducing overheating in summer

Our product recommendation:

There isn’t any insulation material between the rafters; I’ll opt for QUATTRO.
