Our windows and doors are engineered and built to meet and exceed the strictest ENERGY STAR requirements. What does ENERGY STAR certification mean? It means savings in both energy costs and environmental costs. By using NFRC rated and ENERGY STAR certified windows and doors, homeowners can experience savings on energy bills, from several hundred - up to thousands - of dollars per year.
Our vinyl windows and patio doors are designed for remodeling and replacement applications. NOTE: The intent of these specifications and guidelines is to help ensure that new, energy saving, high performance windows and doors are installed in a manner that will complement their performance.
