    Energy-efficient double glazing installations, designed for you

    Achieving the very best energy grade ratings, our innovative double glazing works by having two panes of glass which surrounds an argon-gas filled chamber, stopping currents of cold air entering and eliminating the escape of heat. As it boasts exceptionally low U-values, replacement double glazed windows will leave your home in the Bristol or Reading area comfortable and warm. Not only will they improve your home’s carbon footprint, but our range of bespoke double-glazed products will also enhance your home’s kerb appeal, adding value to your home.

    Double glazing or triple glazing?

    The best glazing solution is dependent on your individual circumstances. However, our modern double glazing provides the optimal performance for homeowners across the South of England. If you reside in a coastal area, or on a busy road then triple glazed windows may be more suitable for you. Read here for a comparison of double glazing and triple glazing, or speak to one of our experts who can advise on the best for you.


    Stay up to date with our latest tips and advice:


    • Energy efficiency: Compared with single glazing, double is significantly more energy-efficient and thermal insulation is improved as heat has to work twice as hard to escape. With the highest possible energy rating of A+12 energy rating, it will help lower your energy bills as you will notice throughout the colder months that you will need your heating a lot less.
    • Sound insulation: Due to the better insulation that double glazing provides noise pollution is also noticeably decreased for a comfortable inside atmosphere.
    • Safety: Two panes are better than one so double glazing makes it harder to break through and as they are sealed tightly it is difficult to force double glazed windows open.
    • Less condensation and damp: A common problem with single glazed units is damp and condensation. Double glazing eradicates this due to the internal glass pane being a closer temperature to the rest of the room.

    How does double glazing work?

    A double-glazed window incorporates two panes of glass-enclosed within a sealed unit. Divided by a gap of at least 12mm, a double-glazed window can be filled with either air or argon gas. The air or gas-filled gap insulates against heat transfer between the different temperatures, the outside, and your home. Acting as a break, the air cannot circulate; consequently, slowing down the movement of heat and reducing heat loss.

    Does double glazing reduce condensation?

    Condensation can be found on both the interior and exterior of a window. Triggered by a temperature difference between the outside and the inside of the window – the cooler surface will attract any available moisture. Double glazing reduces the exterior and interior temperature difference on the glass, therefore lowering the probability of condensation.

    Is it worth replacing double glazing?

    It is always worth replacing double glazing if the double glazing you have at the moment is letting condensation, letting a draft into the house or are older than 25 years old. Replacing the double glazing will stop the drafts and condensation. Even replacing older double glazing with the latest technology can all add up to making your home more comfortable and energy efficient.
