Double Glazing FAQs

At Everest, we understand that choosing new double glazed windows can be a daunting task. So to help you here are some frequently asked questions which you might find useful.

  • +
    How much does double glazing cost?
    The cost of double glazing is dependent on so many factors such as style and materials. Many websites do offer lists of prices of their double glazed windows, but these are usually the cost for a basic off-the-shelf window and often without the cost of installation. At Everest, our products are made-to-measure and customised to your taste and home, which is why you won't find a price online as there are too many contributing factors.

  • +
    How long does double glazing last?
    There is no reason why quality windows can’t last for the lifetime of the property if well maintained. However, not all windows are created equally, for example timber windows will require some maintenance to maintain paintwork. Invariably this comes down to personal preference lower quality windows for example may have no gas between the panes limiting their effectiveness at reducing warmth in a room. Others may use poor quality seals which perish and result in draughts after around 10 years.

    How does double glazing reduce noise?
    Using double glazing in your home can reduce the energy of sound waves and help reduce the volume of external noise from entering your home. By coupling double glazed units with Acoustic glass you can increase sound proofing further. This can make a significant difference when you suffer with noise pollution.

    Read more: Acoustic window range...
  • +
    Will new double glazing stop condensation?
    Condensation is caused by a temperature difference between the outside and the inside of the window - the colder side will attract any available moisture in the local atmosphere. It can appear on both the interior and exterior of a window. New windows really should solve the problem by reducing the exterior and interior temperature difference on the glass. The risk can be reduced further by increasing air circulation.

    What types of glass are available for windows?
    You may be surprised by the number of glass options for your new windows, and it is important to understand which would be best suited for your requirements. Standard glass is called ‘Low E’ and is a great all round option for energy efficiency. Low Iron glass offers high clarity and energy efficiency. Toughened glass is five times stronger than regular glass and laminated glass, contains a plastic interlayer offering better insulation and resistance against damage.
