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.
