The quality of the windows that you use in your home will determine not only your home’s curb appeal, but also the energy-efficiency and the thermal comfort in your building, therefore checking the product specifications is a very important step towards getting the best window solution. Here are the most important ratings to check:
- The U-factor – this parameter will tell you how well your windows will keep heated air inside your rooms. The lower the U rating, the more efficient your windows;
- The solar heat gain coefficient – the parameter tells you how well your windows keep the sun’s heat outside. Like in the case of the U-factor, the lower the rating, the better;
- Visible transmittance – the rating will show how much light can come in through your windows. The higher the value, the more natural light you will get;
- Air leakage – the figure tells you how much air can come in through your window. The lower the rating, the less air comes in through the window;
- Condensation resistance – this parameter is not compulsory for window manufacturers, but very important, nevertheless. The figure will tell you how susceptible your window is to developing condensation – the higher the value, the lower the risk of problems caused by the accumulation of excessive moisture, see https://dmdbuilders.com.
