    Posted on March 16, 2014 by in Articles

    The right glazing choices can help make your home more comfortable in hot and cool weather.

    There are several glazing options available. Some keep heat inside your home. Others keep heat, noise, light and glare out.

    Glass options

    There are several other types of glass available:

    • Reflective glass, tinted glass and spectrally selective glass reduce the amount of heat and ultraviolet light that can get in (ultraviolet light causes fading).
    • Laminated glass is two sheets of glass bonded with a plastic or resin layer. It absorbs ultraviolet light and reduces noise. If it’s hit, the glass is held together by the resin layer.
    • Toughened safety glass is much stronger than standard glass. It’s designed to withstand direct impacts or shatter into small chunks if broken
    • . Laminated glass is the best option for noise, as well as being safe and secure. Reflective, tinted and spectrally selective glass are options for keeping summer heat out.

    All of these types of glass can be used with double glazing, which is the best option for winter comfort.

    Double glazing

    What is double glazing?���������

    A double-glazed window uses two panes, separated by a gap which is filled with air or an insulating gas such as argon. It is also known as an Insulating Glass Unit (IGU).

    Although gaps can vary between 6 and 12mm, a 12mm gap is assumed in most R value calculations.

    You can vary the glass you use for the two panes in a double glazing unit, and you can choose two different types of glass for each pane.

    If you are retrofitting double glazing to your existing windows, there are three main options:replacing the whole window frame with new frames and glass

    • installing inserts into your existing window frames � this is a cheaper option if your window frames are still in good condition
    • installing secondary glazing.
