Double Glazing for Thermal Insulation

Low e glass 2

What is Low-e Glass?

Glass used in double glazing window for thermal insulation is known as Low E, or low-emissivity glass. It has a transparent metallic coating that works in two ways to economise heating energy. The dual action coating reflects heat back into the room, whilst allowing heat and light from the sun (known as passive solar heat gain) to pass through. Thermal insultion glass should be used on face 2 or 3 of a double glazing unit.
