30% of the heat is lost through the roof of an insulated house
Insulating the loft is an effective and easy way to reduce your heating costs and your CO2 emissions. The lambda value (λ) is important for thermal performance. The lower the value, the better the insulating performance of a material. With a lambda value of only 0.036 W/(m*K), STEICOflex has one of the best thermal performance values of any natural insulation materials.
Loft renovation with STEICOflex
The first layer of STEICOflex is laid between the ceiling joists and for maximum thermal performance, a second layer of STEICOflex is laid to cover the joists. This type of renovation requires no specialist PPE and is an ideal solution for both professional installers and DIY projects.
- Existing ceiling joist
- STEICOflex between the joists
- 140mm of STEICOflex across the joists
