Energy Efficiency

Did you know that up to 20% of your home’s heat can be lost through windows? Our team can help you make sure your new windows are as energy-efficient as possible. We find that the frame is the best starting point. As a natural insulator, uPVC is one of the most energy-efficient materials, and Liniar’s multi-chamber design makes it more difficult for heat to escape through windows.

Glazing also plays a huge part in energy efficiency. Double glazing is still the most popular choice, although triple glazing is increasingly popular with our customers. Whether you choose two or three layers of glass, we use low emissivity glass, or “low-E glass”, which reflects heat into your home with an invisible coating.
