Fitting double glazed windows to your home is a fairly easy and inexpensive way to conserve heat and lower your utility bills. Double glazed windows come in a variety of finishes and styles, they can be made to suit any property and work well to keep out noise, keep your home warmer and effectively lower your carbon footprint.
How double glazed windows work
For double glazed windows to be efficient they should have 2 sheets of glass, usually with a 16mm gap between them to trap air, sometimes this gap is filled with gas. Triple glazed windows differ as they have 3 panes of glass. To find the most efficient double glazed windows you should look for the Energy Saving Trust logo or BRFC rating.
Depending on the style and quality of your double glazed windows there can be a few differences in how well they perform. This can include how well or poorly they stop heat from passing through the window, the amount of sunlight that can travel through the glass and how much air can escape or leak in or around the window and frame.
