Insulation properties of PUR foam with
different blowing agents.
12. Thickness of insulation in order
to achieve same U-factor*:
Why PUR Materials for the Construction Industry?
There is only
one clever
way to build
a passive
house
150 m2 house with 400 [mm] MW gives approx. 7 m2
extra living room using 270 [mm] PUR!
[W/m²K]
*U-factor: ability of a building element to conduct heat

Lambda, foam
13. Why PUR as technical insulation?
Insulates better.
Good mechanical properties.
Sustainable.
Durable.
Resistant to chemicals.
Resistant to fungis, bacterias and moulds.
Temperature stable.
”No” water uptake.
Easy to form and work in.
