This home in Ivyland, Pa. had 6 large picture windows, and 12 casement windows installed. The front of the home has a southern exposure and the constant sun was a concern for these homeowners. For the southern exposure windows we installed our Ultra U 12 coat low e glass, with a SHGC of .22. SHGC is a measurement of how well the low e glass blocks out the suns rays. Our customers are so happy that the southern exposure part of their home is now, just like the rest of their windows.
