In summer, strong direct sunlight strikes through window onto people and interior surfaces, creating overheating and discomfort. Windows with low solar heat gain coefficients SHGC will reduce the solar radiation coming through the glass and associated discomfort. Low solar heat gain low-E glass reduces heat gain while still providing abundance of light and view. Our high performance uPVC double glazed windows with new glazing technologies not only reduce energy costs but make homes more comfortable as well, we can go as low as 0.11 SHGC
