Energy Efficient Windows and Doors

Creating energy efficient homes has never been more important, both for the benefit of the environment, and for our pocket! 

Windows and doors play a big part in how efficient your home is and by reducing the amount of energy lost through them, you can make significant savings on your energy bill. 

At JELD-WEN we provide a range of energy efficient windows and doors that not only keep the heat in, but also insulate your home against outside noise. All our windows are BRFC energy rated. 

How to choose an energy efficient window or door

Not all double glazed windows offer the same thermal performance. To understand a window or door's energy efficiency you need to look at its U Value.

All elements that contribute to the energy efficiency of a home, such as a window or door achieve a U Value. As a rule of thumb, the lower the U Value, the more energy efficient the window or door.

Another method of establishing a window's efficiency is through its energy rating. Windows are rated between A+ to G in a similar way to your fridge or freezer, with A+ rated products providing better performance than those rated G. We offer an A+ energy rating on our softwood casement window range.

Replacement windows

Building Regulations dictate that replacement windows should achieve a minimum U Value of 1.6 w/m2k (or an energy rating of C or better) and replacement doors 1.8 w/m2k so always ensure you buy products with this minimum performance rating.

All our windows and composite doorsets are available in this range, with our highest performing window reaching a U Value of just 0.8 w/m2k.

New build

The requirements for new build are based on the overall performance of the entire building and we need this information to ensure we supply you with the correct product.

Increased performance 

You could further increase your home's energy efficiency and save money on your bills by choosing options such as triple glazing or double glazing with an even lower U Value, achieved by use of high tech coatings on the inside of the glass and special gas within the unit rather than just air.
