At GIS we supply and install stylish quality UPVC double glazing that will give your home character and shape the atmosphere of the interior. Our new generation of double glazed windows remain functional and retain a nice look without the need for expensive maintenance. The new materials and technologies used to manufacture our windows allow for excellent sound and heat insulation, sustainable performance, easy 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. Our UPVC double glazed windows are characterised by very high performance static and thermal insulation because of the  weatherseal gasket and multi-chamber  The gasket has a 99% memory recovery and retains its shape year after year, which means the quality of the seal on your windows is not compromised and gives the best acoustic and thermal performance. The multi-chamber construction of our UPVC windows is designed to improve strength, thermal and acoustic performance by eliminating heat and The combination of the glazing, spacers, seals and frame design results in a window which reduces noise
