    High Quality Double Glazed Windows

    You can be confident that you’re installing high-quality double-glazed windows when you choose RHI Home. Our double-glazed windows are individually crafted with new glass, frame and security technology in mind, and will help your home not only transform the look of your property, but make it more energy efficient, too. With more than 20 years’ experience behind us, we’re market-leading specialists with a reputation for offering our customers the best in attractive, energy-efficient windows.

    For almost half a century, we’ve been developing and installing double glazing in houses across the UK, helping to make homes warmer and more secure. Whether you’re replacing original windows in an older property or trying to reduce your heating bills with energy-efficient glazing, we’ve got a window that’s right for your home.

    Our double-glazed windows will not only make your home feel cosier, but they’ll also give it a facelift and transform the look of the property immediately. Each of our double-glazed windows is A-rated as standard and feature two equal 4mm glass panes separated by a 16mm cavity. This helps to achieve excellent heat retention and deliver a high level of 31dB sound insulation to help dampen outside noise. We also offer further sound-reducing window options.

    Double-glazed windows from RHI Home are incredibly customisable and are available in a choice of materials, styles and colours. Regardless of which product you choose, all of our frames are incredibly energy efficient, with a minimum B-energy rating, surpassing the Building Regulations’ requirement of a C rating. Most of our double glazing achieves an A rating as standard, though A+ rated windows are also available. This means your home could actually gain more “free” heat than it loses, resulting in much lower heating bills. If you’re looking for A++ performance, our triple-glazed windows offer even higher levels of performance.

    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.
