While it may be tempting to opt for a lower grade, cheaper products, this could lead to higher costs, not only in bills but further down the line when it becomes time to replace the door, or window because they’re just not effective enough. New builds are increasingly subject to minimum energy ratings, so future-proofing your home helps keep it up to date.

These glass, frame and roof ratings are calculated by the British Fenestration Rating Council (BFRC). This uses a particular rating equation that looks at a products solar factor to see how much heat is gained from sunlight. They also measure how good a product is at preventing heat from escaping and window/door air leakage.

The score is compared to a table which puts the window/door in its correct grade, which is usually a negative number. An A+ rated window would be 0 or greater, while G is anything lower than -70.
The rating system is ideal, as it clearly identifies the best performing window as a system allowing consumers to see the costs and benefits of energy-efficient windows to make an informed decision.

With energy bills on the increase on an almost yearly basis, putting pressure on families heating their homes, A+ rated double glazing provides the ideal solution to a warmer, welcoming and more comforting home.
