There are several factors that go into preventing heat loss in the winter and keeping your home cool in the summer. The type of glass, the number of panes, and the quality of the frame are all important for heat management. The most overlooked component is often the installation. If a window is improperly installed or damaged during installation, there could be gaps between the window frame or problems with the seal.
