Understanding Window Efficiency Ratings

How to understanding your windows efficiency rating

One detail you may have noticed while you are shopping for windows and doors would be the energy efficiency ratings which are similar to the ratings used on household appliances.

Do take note that although these ratings focus primarily on the frame and glass of windows, the type of glazing used will have a bearing on the overall score of the product.

Double and triple glazing windows are put together as a sealed unit. However, if you can look at a cross-section of these windows, you will see that there is a gap between the panes. This gaps forms an insulating barrier. This gap can also be filled with inert gasses like argon and krypton which help provide another layer of insulation.

Windows with little to no metal have a higher capacity of retaining heat. The type of glass used for the window can also contribute to the retention of heat. For example, a window which uses low-emissivity glass can allow ample light to get inside the home without sacrificing heat retention. This is due to the special coating on the surface of the glass.

Double or triple glazing?

If you are choosing between double and triple glazing, which one is better? There is no single correct answer to that question, and there are different factors to consider like the size, location, and orientation of your home, the total glazed area as well as the overall levels of insulation. There are some instances wherein double glazing can be comparable to the efficiency of triple glazing.

Here at Spectus, our range of windows and doors has been designed to be energy-efficient. We strive to achieve a Band A+ rating for our windows by using a six-chamber sash and a five-chamber outer frame. Used in conjunction with glazed units and argon-filled triple glazed units, our windows have a WER A++ rating.

By eliminating the need for Krypton gas-filled units, we can substantially reduce costs. In addition, our innovative Aeroframe thermal wall technology for our window design bolsters thermal performance.

But what do all of these mean for you?

Using energy-efficient windows for your home offers a few key benefits. For one, you will notice a marked decline in your energy consumption which translates to cost savings. Additionally, lower energy consumption also means you have a smaller carbon footprint. Energy efficient homes can make your home more comfortable by eliminating cold spots and draughts. These windows can even help reduce external noise coming inside your home.
