What is external insulation?
With external insulation the material sits on the outside, beneath the covering. Your roof structure stays visible inside and you lose no space. This is also called a warm roof.
Advantages
- No loss of space inside
- Beams and rafters stay in view
- Very effective against cold bridges
- Ideal to combine with a new roof
When to choose external insulation?
External insulation is the logical choice when the covering is being renewed anyway, or on an extension. It is a bigger job than internal insulation, but the result is excellent and low-maintenance.
