Thermal conductivity value


Improved heat flow through ALPET®

The following illustrations show how the heat flow is significantly improved by ALPET®. This leads to energy savings and lower heating costs.

Improved isothermal curve due to ALPET®

In the following illustrations, you can see how the isothermal curve is significantly improved by ALPET®, which leads to an increase in the quality of the window.

Thermal conductivity insulation bar

Reference values:
ALPET® bar width 5 mm - 0.105 W/mK
ALPET® bar width 8 mm - 0.080 W/mK

Reduced thermal conductivity values

In aluminium glazing and aluminium facades, the new ALPET® insulating bar develops its full insulating power. The Uf values are significantly improved depending on the cross-section and reach values that are notably below the existing ones.
