Thermally insulating glass (also known as low-emissivity or low-E glass) usually forms the inner pane of an Insulating Glass Unit (IGU).

The glass has a transparent metallic coating that reflects heat from radiators or fires back into the room, rather than allowing it to escape through the windows. At the same time it allows free heat and light from the sun (known as passive solar heat gain) to pass through the glass, warming your home and further contributing to the energy efficiency of your windows.

Benefits

Using thermally insulating double glazing is the best way to improve the energy efficiency of your windows and make your home environment more comfortable.

Improved thermal insulation - reduced heat loss saves you money on your heating bills.

Improved energy efficiency - reduced need for heating helps to save energy and protect the environment.

More comfortable rooms - improved thermal insulation means fewer cold spots and drafts near windows and doors.

Less condensation - the inner surface of the glass stays warmer, reducing internal condensation and prolonging the life of the windows.

Thermally insulating glass can be combined with many other products for multi-functional glazing, such as low-maintenance, solar control, noise reduction, decorative glass and enhanced safety and security.
