Hulmursisolering

The offer includes insulation of three-layer walls (hulmursisolering) using PUR foam.
Unlike blown-in paper or rockwool, its strong expansion properties mean that it can force its way into difficult areas, such as around wires, boxes, protruding nails and screws, and other spaces that tend to hang up gravity-fed cellulose.
I use the latest closed cell foam from Den Braven with 30 years warranty.

Advantages of PUR foam insulation

- Foam has excellent insulation lambda = 0.030W/(m*K), it is 30% higher than insulation of wool and polystyrene.
- Suitable for applications in hard to reach places.
- Does not mold, anti-fungal.
- We drill only 7mm holes in the fuge without damaging bricks.
- The applied product forms a monolith with an insulated surface, thanks to which moisture does not collect between the wall and the product.
-Does not absorb moisture.
-Does not settle down after years like granular wool and paper.
-The ratio of closed to open cells 70% / 30% makes the wall "breathe" all the time.

Price from 85kr per m2 of wall, all included.
