If you want a home that’s both warmer and more energy efficient, our A++ rated triple-glazed windows are the perfect choice. As well as trapping in warmth, they have the best acoustic performance and sound insulation properties of our windows. With our triple glazing installed, your home will be cosier, as well as benefit from less noise and increased security. You could also enjoy cheaper heating bills.
To maximise the sun’s energy, our triple glazing features two panes of Low E glass and one pane of Low-Iron glass. The invisible metal coating on Low-E glass reflects heat back into your room, making it much warmer and cheaper to heat. That means with triple-glazed windows, you can increase the energy efficiency of your home by up to a third compared to homes with double glazing.
Triple glazing is ideal for north-facing windows or elevations where there is little benefit from natural sunlight. Here, triple glazing will give you the best insulation properties of any of our windows. As you probably won’t need it in every room, you can mix and match the windows in your home to suit the aspect and elevation of each room. Our experts can talk you through each room to help you choose the best combination for your needs.
As well as excellent heat retaining properties, the extra glass panel in our triple-glazed windows also provide fantastic sound insulation, so they’re ideal for homes with problematic background noise.
