Corona home, we added energy efficient replacement windows and an elastomeric heat reflective coating. The windows benefits include not only energy efficiency keep you more comfortable, but they are quiet as well. Plus, the beveled exterior master frame enhances aesthetics. They come with a dedicated pocket sill design with triple weather stripping prevents air and water infiltration. The sliding window operating sash removes easily from the inside for convenient cleaning. A Positive interlock system, structural metal reinforcement, and dual action cam locks at the meeting rail provide resistance to outside elements and forced entry. Lastly, Neat® naturally clean glass. It harnesses the sun’s UV rays to loosen dirt so water can rinse it away, leaving windows virtually spotless. The coating is a lifetime "Cool Life" that provides superior protection from the elements and reduces energy costs.
