    Maximise the sun’s rays for optimum heat retention and warmth by installing our triple-glazed A++ rated windows. The extra glass panel reflects more heat back into your home, making it cosier and helping to cut your heating bills. They’re our top choice for cutting out external noise, too, ensuring you feel a big difference in any room.

    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.

    We design every window with our three values in mind

    Energy Saving

    Our uPVC double-glazed windows are designed to help keep your house cosy warmer in winter and cooler in summer. Two 4mm glass panes separate a 16mm cavity to reduce heat loss through your windows. This means your home will be more energy efficient and you could save money on your heating bills. Our top-performing A++ rated triple-glazed uPVC windows are a great choice to reduce heat loss even further with three panes of 4mm glass.

    Reduce Noise Levels

    A big benefit of uPVC double-glazed windows is their ability to help reduce noise pollution from outside. Our A-rated modern uPVC windows provide a sound protection level of 33db. If you live near a busy road or on a flight path, our sound reducing uPVC windows are the best option. Offering 39db protection, our safe and sound double-glazed casement windows help keep the street noise where it belongs.

    Strength Against Intruders

    RHI Home’s white uPVC double glazed casement windows carry the Secured By Design accreditation. You’ll be joining other RHI Home window homeowners who benefit from rigorously tested modern uPVC windows designed to withstand forced entry and protect against break-ins. uPVC double-glazed windows are fitted with key locking security handles and shoot lock bolts as standard.
