    Energy efficient windows as standard

    We care about the environment and helping you to reduce your heating bills. That is why all our windows come with thermally efficient glazing as standard, which conforms to Government environment guidelines. They can even reach up to an ‘A+12’ rating in the Window Energy Rating system (WER).

    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.

    If you’re tired of underusing rooms because they are draughty or because the glazing has become misted, replacements are a very cost-effective solution. Modern uPVC, aluminium and timber frames (all of which we offer) improve the retaining of heat and weatherproofing. This makes for more pleasant living areas, even if you live in a coastal area of the South or one that is particularly windy.

    Sound insulation

    Due to the better insulation that double glazing provides noise pollution is also noticeably decreased for a comfortable inside atmosphere.


    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.
