WitrynaIn a cool climate a higher SHGC will allow more solar heat to pass through the window and help to heat the home, whereas in a warmer climate a lower SHGC will allow less solar heat to pass helping to keep the home cooler. Glass tints and low-e coatings offer are some of the options to consider to get the best result for your project. WitrynaNearly half of all the energy that comes from the sun is visible light, so while lower SHGC’s may reduce the amount of solar energy entering the building, there is a trade-off between the darkness of the window and the SHGC. It is important to note that Low E windows are often thought of as high performance, but by definition, a Low E window ... WitrynaA window with a low SHGC cuts down that heat significantly and means lower cooling bills. The SHGC rating on the labels is shown as a number between 0 and 1. The lower the number, the better the window is at blocking solar heat. Low-E glass is the hero here. Low-E glass has a coating that reflects heat back to its source. mbsr topics
