Thermal insulation

The reinforced plastics composites are a highly efficient thermal insulators. This advantage and good strength properties are used in the course of producing of windows, fire-stopping doors, but also in thermal insulated truck and freezer industry.

Advantages of reinforced plastics composites as thermal insulators are:

Thermal properties:

Our profiles can be used without restriction between -20°C and +80°C, in the case of special resins -20°C and +150°C.
Coefficient of linear expansion: 8 – 10.10-6 K-1
Thermal conductivity: 0,2 – 0,4 W/mk

Special fire resistance applications

For applications where fire resistance and low smoke emissions are crucial, one can use special phenolic or modified acrylated resins.
