Insulated Glass Units

Energy is becoming more and more expensive. Double glazing provides an excellent solution to keep your building cool  in summers and warm in winters. It also ensures that noise level remains low. Double glazing has quickly become one of the most popular and useful form of glazing world wide.

Double glazing is essentially two layers of glass placed together in a window frame and sealed with special chemicals  which are imported form Germany/Italy. Between both layers of glass, a space exists, therefore reducing heat transfer through glass. When glass panes are placed together, they are known as double glazed units of glass. The glass has thermal and acoustic properties, allowing it to form an excellent source of insulation whilst simultaneously allowing the light to enter your home and office. It noticeably helps to reduce your electricity bill. A state of the art plant from Germany/Switzerland of Bystronic-Lenhardt has been installed to produce IG units.

Let's take a look at the main components of a double glazed surface area.

The glass used in double glazing needs to be a very specific kind to ensure that maximum insulation, noise reduction and light is achieved. Glass will generally need to be 6mm thick. Glass may be clear, tinted, coated or Low E, depending on the specific function required of the double glazing. Tinted glass undergoes a specific treatment that allows the glass to cope with thermal stress, storms and to encourage the re-absorption of heat for highly effective insulation. Double glazed windows that are coated may have a reflective finish or a mirror finish.


The two glass panes are separated by a small segment that allows the air between the two panes to be sealed. When a space exists, heat will not travel and disperse - this is how double glazed windows prevent the home from becoming too cold. The spacers themselves are made from non-conductive materials to prevent heat escaping from the window.

Building the Double Glazed Window

Double glazed windows are customized to fit the particular space requirements. The double glazed panes are created and then spacers for each panel are cut and fit to the correct size. The glass panes are carefully cleaned on a washing line that ensures the surface remains clear. Then, an adhesive is placed on both opposing sides of the spacer and the glass panels are attached. The outside edges of the panel are sealed using silicon adhesive. The glass is coated or finished according to the manufacturing specifications.

How Effective Is Double Glazing

Double glazing provides great insulation for your home. The glass is specifically designed to contain heat transference. Most double glazed windows will last for around 20 years and continue to function effectively, so it is a good idea to buy windows that have a long warranty. If double glazed windows are particularly exposed to the elements, they may not last quite as long. There are many highly beautiful double glazed window and door options available.

With double glazing you will experience:
