Double
Glazing
A double-glazed window is made up of two panes of glass separated by a gas-filled sealed space. The sealed space between the two panes of glass acts as an added layer of insulation, reducing the amount of heat escaping in winter and having the reverse effect in summer by preventing unwanted heat from entering your home, ultimately reducing your energy costs.
At Commercial Joinery all of our custom-made windows and doors are available double glazed, including our specialised double-hung windows, casement windows, french doors, Bi-fold windows and doors and sliding Windows and Doors.
