What Is Double Glazing Windows?

An upgrade to single glazed glass that is made to measure for uPVC and wooden frames.

Double glazed windows use two single glazed glass panes which is constructed together to create a sealed layer of usually argon gas or air in between. These units are really good additions to modern homes as they offer better energy efficiency, better insulation and help to lower your energy bills.

Advantages

  • 1
    Retains Previous Heat In

    Double glazed windows have a multi-purpose role in keeping cold air out and standing in as an insulating layer to lessen the effect of heat escaping through the glass unit. Utilising the trapped air or gas in the middle layer as a poor conductor makes it tough for the heat to be transferred through the window. It performs as an effective insulating barrier because likewise, the level of cold air that seeps through the glass unit is also reduced.

    Reduced Energy Bills

    With a sealed and airtight assembly, double glazing windows consist of a thermal insulation section. It lessens the effect of heat being transferred in and out of the window construction through which it maintains relative control to keep to a stable temperature. Of course, this technique of combining layers does not require more heat to be used as the temperature is sustained for longer and the benefit is seen from lower energy bills due to less fuel consumed.

    Less Condensation On Glass

    Enabling the use of two sealed and airtight panes of glass with an insulating space in between, restricts the heat exchange in that space. This helps to regulate the temperature on both panes to prevent condensation from building up. Low emissivity, also known as Low-e glass are better at doing this and recommended by experts when replacing windows as there is much lower chance of those unsightly water droplets appearing inside the glass unit.

    Better Soundproofing

    Windows with double glazing have an advantage over single glazing as they create a thicker barrier between the home and the outside atmosphere for improved noise insulation. The space inside the unit’s layers and if filled with argon which is a heavy gas you will find that they limit how the sound travels through the glass unit. What you benefit from is effectively soundproofing.

Disadvantages

  • 1
    Higher Initial Costs

    Energy efficient windows and doors cost more that single pane units. The reason is that you are paying more for the extra glass sheet and to have the sealed insulating middle layer. Manufacturers have to deploy more specialised machines to enable this and have to offset the cost by adding a premium to the product. Fortunately, the added price that you pay is eventually paid off from the savings you can achieve in energy bills.

    Whole Unit Replacements

    A failed sealed glass unit where condensation has begun to form inside renders the energy efficient rating as non-existent. A lot of the times, the hardware is not cost effective to repair and will require a full glass unit replacement.

    Modern Designs

    Replacing old windows? Double glazing windows are usually manufactured in modern designs, although there are few with traditional features. Even with similar looks, it is difficult to match as they are much thicker frames and can look irregular at second glance. For a flawless and appropriate style, it may mean that all the windows of your property will need replacing.

    You can get double glazing windows with an energy rating of low E to the highest A++. However, when ordering a new window, by law the lowest you should get is grade C. This is the grade that the Energy Saving Trust state that a detached house with comprehensive double glazing should save £95. We offer a savings of at least £110 a year as our uPVC glass windows begin at rating A and reaches the A++ with our premium products.
