Before and After thermal imaging showing insulation properties of our windows where external temperature is lower than internal temperature. BEFORE greater heat transfer from inside to out through glazing and frame. AFTER heat is retained, closing the thermal wound in the wall. The silver coating of the soft coat lowE glass reflects heat back into the room. This results in increased glass temperature as indicated by the orange colours of the thermal image
