What glass is used for double glazing?

The glass used in a double glazed window will be chosen based on the size of the unit and is designed to withstand human impact and wind. The thermal performance of this glass can be improved by adding a low-emissivity (low-e) coating. Low E glass has a transparent metallic coating that works to reduce energy use, by reducing the rate of heat through the glass surface.  

The coating works in two ways:

  1. Reflecting heat back inside a building
  2. Reflecting direct sunlight back out when used for solar control 

Heat travels relatively easily through ordinary glass – in winter from inside to outside and in summer from outside towards cooler air inside. This process can be slowed with insulation, which is why we use Chevron insulated glass units (double glazing). 

They can be manufactured using multiple combinations of glass using clear, tinted, laminated, acoustic and low-e sheets. All units we install are toughened for your safety.
