A superior technology designed to minimise energy loss through your windows

Warm Edge Technology

What is Warm Edge Technology?

Up to 80% of energy loss through a window occurs at its edge. 

Warm edge products aim to minimize this energy loss and reduce heat loss through windows.


'Warm Edge' within double or triple glazing units refers to the spacer used to separate the panes of glass.  If the spacer material is less conductive than traditional aluminium spacer, it is termed warm edge.  None-metal spacers generally have a lower thermal conductivity value.
