How K Glass Works

The glass in your windows absorbs heat.   Without the benefit of K glass, this heat will be radiated towards the colder surface which is normally on the outside.     K glass has a so-called low emissivity coating which is positioned on surface 3 (counting from the outside) of the insulating glass unit.  

The low emissivity coating is a poor radiator of heat.   Therefore, the heat absorbed by the coated glass does not travel across the air gap to the outer pane and the cold outside.      Instead the coating reflects the heat back into the room.   

K Glass is a cost effective method of retaining the heat inside your home as the low emissivity coating bounces the heat back into the room.

Heat from the sun’s rays is also bounced back into the room. – this can be referred to as “passive solar gain”.
