Replace your old windows with energy-efficient windows. Improve the energy efficiency of your home with the right glazing for your windows. Not only will it reduce draughts and cold spots, but it will also insulate your home against external noise and reduce condensation. Unlike a single-paned window, energy-efficient windows will have a gap of air between two or three glass panes which act as an insulator making it less likely for heat to be lost to the outside air. The optimum gap size is 16mm although smaller gaps maybe suited in some cases. Depending on your budget and your needs, you can fit secondary glazing, upgrade double glazing or install new double or triple glazing. Contact us through call (020 3582 0855) and visit our Site.
