Warm Edge Technology

Warm Edge Defined

Warm Edge Technology is a general term for a spacer system that has a better thermal performance than standard aluminium spacer bar. 

The definition of a thermally improved spacer as provided by EN ISO 10077 is one with a thermal conductivity value of  0.007 W/K. This value is calculated as follows:


∑ (d∙λ) ≤ 0,007 W/K


d=Thickness of the spacer wall in m.

λ =Thermal conductivity of the spacer material in W/(mK)
