Energy Efficient Glass


Energy efficient glass can be a very confusing subject, here at Somerville Glass we can answer any of your questions and provide expert advice to ensure we achieve the right outcome for your job.

Energy efficient glass is a number of different products, but basically energy efficient glass will act as insulation for your home, reducing heat gain and reducing heat loss. In the past high performance glass has been seen an expensive option, as far as insulating your home was concerned, but the cost of energy efficient has dropped significantly over the past few years and the benefits have only increased. With energy costs rising and the benefits of reducing your carbon footprint becoming increasing factors, there has never been a better time to upgrade the glass in your home.

Types of energy efficient glass

There are two main types of energy efficient glass, Low E coated glass and double glazed units.

Low E coated glass is where a highly durable coating is embedded in the glass surface. This coating gives the glass something called low emissivity, this coating reduces the amount of heat gained through the glass in summer by reflecting the suns radiation away from the house. In winter the glass works with the opposite affect, the low e coating on the glass prevents the heat in the house from escaping through the glass by reflecting it back into the room.

Here is a short intro to energy efficient glass.


Insulated glazing (IG) or more commonly known as double glazing is double or triple glass window panels separated by an air or other gas filled space to reduce heat loss or gain from your windows.

Insulated Glass Units are manufactured with glass in a range of thicknesses. Laminated or toughened glass may also be used as part of the construction. Most units are manufactured with the same thickness of glass used on both panes but special applications such as sound reduction or security may require wide ranges of thicknesses to be incorporated in the same unit

Single Glazing

Standard single glazed widows offer very little to no energy efficiency and allow heat, cold & sound to travel freely through the glass.

In Summer, heat passes through your windows and into you home.

If you have cooling, it also passes through your windows to the outside. This causes the interior of your home to heat up, overworking your cooling and increasing your energy bills.

In winter the opposite is true, cold passes through your windows, cooling your home while your heating passes through the window to the outside. This overworks your heaters, increasing your heating costs.

Double Glazing

Double glazing improves the energy efficiency of your home by stopping not only heat and cold from entering your home but by reducing the amount of heating and cooling leaving your home.

This reduces the need for heating and cooling, thus reducing your reducing your energy consumption and costs and reduces noise.

Combining the use of special ‘Low E’ glass, argon gas filled double glazing units and a variable space between each pane of glass. Heat, cold and noise are ‘reflected’ back from the first pane of glass, reducing energy consumption and costs and reducing noise.

  • I just wanted to say how very impressive your organisation is. After a smashed window on a Friday afternoon, one phone call later, and the technician was here exactly when you said he would be, was polite, professional and the window was replaced in a jiffy. I only wish more trades offered the kind of service that you do, and that all little accidents were so painlessly taken care of.
