Welcome to the European Polyurethane
(PU) insulation website

Here you can find information about the benefits of insulation,
and the role of PU (PUR / PIR) in achieving energy efficient buildings and a sustainable future.

Light weight

Since around 97 % of the volume of the polyurethane foam is trapped gas, polyurethane insulation is extremely lightweight …

Low indoor air emissions

People spend about 90 % of their life in buildings. Maintaining a healthy indoor climate is therefore of the utmost importance …

Reaction to fire

PU insulation systems exceed the fire safety regulations and insurance requirements for a wide range of applications …

Low thermal conductivity

Depending on the facings and thickness, PU can achieve a thermal conductivity as low as 0.022 W/mK to 0.028 W/mK …

Mechanical resistance

Polyurethane insulation is lightweight but strong. Even at low densities, polyurethane keeps excellent mechanical properties such as compressive stress, compressive strength and creep …

Low thickness

Thanks to its low thermal conductivity, polyurethane can be thinner and still insulate better …

Resistance to water and moisture

Due to its closed cell structure, rigid polyurethane insulation is barely affected by water or moisture: it does not absorb or transport water, i.e …

Temperature stability

Maintaining shape and constant dimensions over very long periods of time are key requirements for insulating materials, particularly when they are exposed to considerable variations in temperature …

Durability and external impacts

Polyurethane rigid foam has a useful life of 50 years and more, and maintains its very low conductivity over time, due to its closed cell structure and ability to withstand external impacts such as moisture ingress or air movement …

Chemical and biological stability

Insulation boards made of rigid polyurethane foam are for the most part resistant to the chemical substances used in the building industry …
