The company’s 5300 Series windows are engineered to offer maximum energy efficiency. These windows feature multi-chambered frames—constructed of durable vinyl—that create effective insulating air pockets for improved thermal performance. They also include the PPG Intercept spacer system for reducing conducted heat loss through the glass. They are available in double-hung and sliding models, and can be manufactured with woodgrain interior finishes, contoured grids and decorative, or V-groove glass patterns. Homeowners can also choose Gorell Glass Protector, which reduces maintenance and makes cleaning easier.
