Roof insulation on the inside by Trudodak

Insulating without removing the roof

For inside insulation we fit the material beneath the existing roof decking, between or against the rafters. This can often be done without removing the covering, which makes it more affordable.

Advantages and points to note

  • Cheaper than external insulation
  • Quick to install
  • You lose a little space under the roof
  • A good vapour-control layer is essential against moisture

Materials

We work with mineral wool, and on request with sustainable materials such as wood fibre. The vapour-control membrane on the warm side is important, so no moisture enters the structure. That is where our experience helps.

Frequently asked questions

Insulation inside: good to know

Do I lose much attic space?

A small part, depending on the insulation thickness. We discuss in advance what it means for your space.

Does the insulation prevent moisture problems?

When done well with a vapour-control layer, yes. That execution is crucial and we watch it closely.
