Composite panels for energy saving

Active environmental protection through effective insulation

In times of constantly fading energy resources and rising costs the subject of energy efficiency and thermal insulation in both construction and industry sector becomes more and more important.

With our COSMO-ENERGY line, we offer a variety of high-end panels with excellent thermal insulation properties as a tribute to sustainable energy saving efforts.

Technical information on the U-value


U-valueU-value or heat transfer coefficient U
This value defines the thermal insulation
behavior of a component
W / (m²xk)
*Thermal conductivity group λW / (mxk)

The calculation of the U-value is described in DIN 4108 Part 4.
