Frequently Asked Questions

  • What are Double Glazed Windows and how do they work?

    A Double Glazed Window consists of two panes of glass with an insulated gap in the middle. Designed to keep warm air in, this sealant will prevent the heat from escaping through your windows and prevent cold air from entering your home.

    Along with energy efficient properties, Double Glazing Windows are known for reducing the amount of sound that enters your home. So, if you are living near a noise populated area (busy roads or train lines) then Double Glazed windows are perfect for you.

    As glass is a conductor of heat, the gap in the middle prevents the heat to transfer. The science behind this is the gap is too small to allow the air to circulate and prevents transfer by convention. Therefore the rate of heat lost through the window is reduced.

  • Why is heat lost through windows?

    The most common way heat escapes from our homes is through our windows.

    Single glazed windows can cause you to lose around 10 times more heat compared to well-insulated areas. The reason for this is because glass is a heat conductor and with a single pane it is more likely to lose heat.

    Upgrading to double glazed windows will help prevent this and will provide you with many other benefits.

  • What are the benefits of double glazed windows?

    During the winter season, double glazing is ideal as it protects your home from cold air entering and warm air escaping. As there is less reason to keep your heating on for prolonged periods it means you can save money on your energy bills.

    The same goes for the summer. Double glazed windows will prevent warm air from entering your home. There are two layers of the glass pane it becomes a lot harder to break into.
