If you want an energy efficient home then one of the best ways to achieve this is with double glazing and insulation. Double glazing simply adds a second layer of heat-loss protection to your windows. Since around half of all the heat lost from your home is lost through the windows, walls and loft, this can make a huge difference to your home’s efficiency.

Single glazed windows are responsible for wasting around 20% of the heat in your home. Replacement windows greatly reduce this, making a good investment for your home and the environment. Double glazing can save 680kg of CO2 every year, not to mention shaving £80-£100 off your energy bills, and adding real value to your home if you later decide to sell.
