Why should I get double glazed windows?
Insulation
Double glazing can reduce heat loss or gain by up to 30% compared to single-glazed windows, making them energy efficient as they lower energy bills and the use of costly central heating.
Noise reduction
Double glazing absorbs sound vibrations and filters out up to twice as much noise pollution as single-pane windows.
Increased security
Double glazing makes it harder to break a window, especially with toughened glass, and can provide peace of mind with an extra layer of protection.
Condensation prevention
Double glazed windows have two panels, the interior of which should remain the same temperature as the air inside the building. This prevents condensation from forming and is much less likely to cause damp and mould.
