Energy-efficient uPVC windows to suit your Leeds home

Windows are one of the biggest sources of heat loss in the home. However, the more energy-efficient your windows are, the more warmth they will retain inside your property. Therefore, leading to a more comfortable home for you and your family to enjoy.

In addition to increased comfort levels, you will not need to use as much fuel on your central heating system in order to keep your home warm. By replacing all the windows on a detached home with A+ rated windows, it’s actually possible to save up to £110 a year on heating costs. Here at TWS Leeds, our windows and doors excel in terms of thermal performance, meaning you can enjoy similar savings for your property.

What are Window Energy Ratings?

Window Energy Ratings are determined by the British Fenestration Ratings Council (BFRC), an impartial organisation who performs independent assessments of windows and doors to determine their energy performance. Windows and doors are rated on a scale of A++ to E, with A++ being the most energy-efficient and E being the least. Since 2010, replacement windows must have a minimum rating of C. However, our windows far exceed this minimum value.

What are U-values?

U-values measure the rate of heat transfer through a structure divided by the difference in temperature across that structure. The lower the U-value, the lower the rate of heat transfer and the better that structure is at provided insulation.
