Energy Efficiency

Our energy efficient double glazed units are manufactured using the latest technology in glass and spacer units, which allows heat generated from inside your home to be reflected back into the room, but also trap heat through solar gain, thus maximising the thermal performance of the windows. The economic and energy-saving properties contribute not only to lower heating costs, but also to reduce air pollution and help to preserve the ozone layer.
