Energy Efficiency

As a company we want to be able to offer an affordable energy-efficient solution to any homeowner looking to make improvements, and whilst energy efficiency is important, it is also essential to consider the type of profile being used, the composition of the double-glazed units and the length of guarantee provided.

Due to the quality of the materials we use, all of our UPVC Windows achieve a C-Rating as minimum standard, and they are supplied and installed with a 10 year guarantee. Other window compositions with higher ratings are available, and we would advise you to call into our showroom to discuss your requirements. Whatever window rating you choose, all of our double-glazed units are fabricated using Pilkington K OW glass for improved thermal performance, and light transmission. This combined with our Edgetech warm-edge Truplas spacer bar, means our windows will make an immediate impact upon the energy performance of your home.

Please use our free Energy Savings Calculator, to see just how much new double-glazing can save you!
