US Daylighting recently completed a window unit in the St. Joseph Catholic Church; a property, which is listed on the National Register of Historic Places. A window with yellow tinted ripple, single pane glass was removed and replaced with the new AeroGlass. The new window has brightened the connecting corridor tremendously. We often don't need to turn the lights on during the daytime hours. Furthermore, with the addition of the AeroGlass, there is a notable difference in the environment - both cool air and heat in the space. We are very pleased with the overall look, which blends smoothly with the historic character of our building.
