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.
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.
