What is Triple Glazing?

A triple glazed unit is a window consisting of three panes of glass separated by argon gas, this means it has an extra layer of glass to insulate your home over double glazing. Our triple glazing prevents heat loss by convection because the air gaps in each unit are too small to allow the air to circulate, and because the argon gas is a poor conductor, it reduces the rate of heat loss through the window.

Save On Your Energy Bills.

Each Designer Door Company high-quality, Triple glazed window comes with a WER ‘A’ Rating as standard. They are designed for enhanced energy and thermal performance, and the multi-chamber design minimises heat loss through the frame. Available with 44 mm, Designer Door Company’s high standards of energy performance ensure that our replacement windows will help save money on home heating bills and reduced carbon emissions.

Our high-performance triple glazed windows which are fitted with Soft Coat Xtra glass and Argon gas will achieve whole window U-values as low as 0.8 w/m2K, and for maximum performance, we use a Warm Edge Spacer bar which retains heat better than standard aluminium spacer bars around the edge of the unit.

Triple glazing units can be used in many styles of frames like sash windows, casement windows, shaped windows, tilt and turn, and French windows, so when choosing a company to help with your home improvement needs, choose Designer Door Company.
