Energy Efficient Windws

Our triple glazed A+12 rated windows offer the best heat retention properties and warmth of any of our frames, making them ideal for north-facing windows. By maximising the sun’s rays, the extra glass panel helps to reflect heat back inside, making your home warmer and heating bills lower.

Energy efficiency and reducing your carbon footprint is important to many AGS customers. To help you compare the effectiveness of each of our energy efficient windows, we use the energy ratings system developed by the British Fenestration Rating Council (BFRC), which is the UK’s nationally recognised scheme for measuring window energy efficiency. The BFRC scheme is used in Building Regulations to show compliance for window replacements; to comply, every window must achieve a C rating or above.

Each window is assessed to measure how well it prevents heat loss, keeps draughts out and how well it absorbs natural free energy from the sun. This combination of factors gives an overall energy rating, ranging from A+ to G, with A+ being the highest rating.

Our UPVC windows achieve an A rating as standard - meaning that they gain more of the suns free energy than they lose through thermal transmittance. Ratings of A+12 are also possible on our UPVC windows. Our triple glazed options, available up to an A+12, offer the best in reducing heat loss. By installing AGS’s windows, you’ll be confident your home will be as warm as possible, saving you money at the same time.

All our uPVC double glazing windows achieve an A rating as standard. The higher the rating, the more energy your windows save, which not only makes your home warmer, but helps to keep your heating bills lower. There’s environmental benefits, too. By consuming less energy to heat your home, you’ll also be reducing your CO2 emissions.

Switching from single glazing to our A rated energy saving double glazed windows will save money and significantly reduce heat loss. Even replacing older double glazed windows to our modern A rated double glazed windows will make a difference. For all round energy performance as well as other benefits, such as better soundproofing and security, you can choose triple glazed windows, which also achieve up to an A+12 rating.

Our A rated windows are available in a number of styles and for even greater energy efficiency, you can upgrade to triple glazing, which is particularly beneficial for hard to heat rooms.
