Energy efficient windows are a great way to save money on energy bills, and make your home more comfortable and sustainable. However, a window’s effectiveness depends on the materials and installation. A poorly installed or ill-suited window can result in a loss of heat that could be as much as 30 percent.
The energy efficiency of a window is rated by the British Fenestration Rating Council (BFRC) and depends on the materials used to build the product. For example, the type of glass, the type of frame, and the overall air leakage of the frame all have a bearing on the performance of the window.
The BFRC uses a scale called WER, or the Window Energy Rating, to rate the thermal performance of a window. The WER measures the window’s ability to retain heat and allow light into the room. The higher the rating, the more efficient the window.
The most energy efficient windows feature double glazing. The two panes of glass are sealed with a sturdy frame. These windows allow for plenty of natural light to enter the house, while preventing cold air from entering. They are also very effective at insulating your home. In addition, they can help to cut the carbon footprint of your home.
Another way to increase the energy efficiency of your windows is to install heavy curtains. Keeping the curtains tight will prevent air from leaking into your home and improve the overall performance of your windows.
A third option is to use inert gas fillings to improve the energy efficiency of your windows. These include argon and krypton gas. The benefits of using inert gas are that it is heavier than air, which reduces the rate at which the glass loses heat. Moreover, inert gas helps to eliminate noise, which is an important factor in the performance of your windows.
The best performing windows are usually made of durable uPVC or aluminium. These materials are extremely durable and require very little maintenance. They are also easy to recycle. In addition, they are available in a variety of styles. In addition, modern uPVC windows are often manufactured with enhanced security in mind.
The average UK home loses up to 25%-30% of its heat through its windows. This makes energy-efficient glazing a practical choice. These types of windows are also great for reducing your carbon footprint, because they use less energy to manufacture. For example, if you replace your single-glazed windows with double-glazed ones, you can expect to save PS65 per year. If you have a detached property, you can expect to save even more.
To find out which window would be the most energy efficient, it is essential to understand the BFRC rating system. Generally, the best windows have a rating of A++ or A+. You can also get an A+ rating if you install an energy-efficient door.
The British Fenestration Rating Council rates windows and doors to provide an indication of their thermal performance. The rating is based on a scale from A to G, with A being the highest. The lowest ratings are the ones that can only meet the minimum requirements set by Building Regulations. The BFRC also assesses the solar gain of the windows and doors.
