Energy Efficiency

Here at Affordable Windows & Construction Ltd, we believe in providing energy efficiency products that will significantly upgrade any home. Our products produce highly advanced multi-chambered profiles, which is the best in the double glazing industry. We ensure that when you install our products into your home, you will start saving money on your electricity bills from day one. 

We install a wide range of double glazed windows and doors to homes in Slough, Burnham, Maidenhead, Berkshire, West London and the Thames Valley. All our energy efficiency products are made from various thermal insulating materials that will keep your home at a comfortable temperature all year round.

Double & Triple Glazing

To help products increase your home’s energy efficiency, install our double or triple glazing panes. Installing double or triple glazing panes into your windows and doors will keep your home nice and warm for much longer. Double and triple glazing creates a thermal barrier between your home and the outside, so no heat escapes the property. They are designed with two glass panes with an air bubble between them, making it almost impossible for anything to come in or out of the home. 

Not long after you install our energy efficiency products, you will notice that you will feel naturally warmer in your home. This will mean you can rely less on your central heating and potentially save you money in the long run!

Weather Resistant

Ensuring you install windows that are weather resistant will also increase your home’s energy efficiency. If there are gaps in your windows that allow air to get inside, this will make your home stay at an inconsistent temperature.

To ensure your home has an extra layer of protection, our windows and doors are designed with weatherproofing materials. Our uPVC windows are designed with tight weather seals, and the glazing is coated with transparent metallic layers. These materials all work together to increase your home’s energy efficiency and reduce wastage.

WER (Window Energy Ratings)

Window Energy Ratings (WER) were established by the British Fenestration Council (BFRC) in 2004. Their goal is to compare the energy efficiency of windows easily. The energy rating is determined by how much energy the window will either lose or supply the property each year. The rankings go from A (the best) to G (the worst), so owners can quickly tell how energy efficient a product is.

British Fenestration Rating Council (BFRC)

The BFRC accredits all our Linear energy efficiency products. The BFRC established Window Energy Ratings to make it easy to determine how energy efficient a product is. 

They use a simple scale made up of rainbow colours so you can visually see the energy ranking of a product. Our uPVC windows and doors all offer exceptional Windows Energy Rankings that will effectively improve our customers’ homes.

Energy Saving Trust

The Energy Saving Trust are an industry leading organisation who are passionate about helping homeowners and businesses reduce their carbon footprint. The Energy Saving Trust approves all our Liniar products. We can guarantee our customers that our energy efficiency products will help them save money on electricity bills and remain warm for much longer.
