Your windows will be entirely fusion welded – sashes and mainframes – to create a solid, one-piece unit that maintains its strength over the years. We offer a state-of-the-art fusion process that ensures frame and sash corners won't have the excess variance found with other welding techniques. (Standard on all Premium Series and Contractor Series windows and doors)
InterForce II is a fiberglass reinforcement adding superior strength and stability to the meeting rails. Premium Series only. (Not available on sliding doors.)
R-Core® insulation is pre-expanded high-density solid-polyurethane which is the same material type used in many refrigerator/freezer doors. It prevents voids and settling and results in even distribution of the maximum insulating barrier. Premium Series only. (Not available on garden windows, basement windows or sliding doors.)
Your windows and patio doors can be ordered in 1/8” increments to accommodate any replacement application, providing a perfect fit and minimizing installation time and special trimming requirements.
New Generation Vinyl withstands harsh weather and wear-and-tear better. This rugged, maintenance-free, New Generation uiPV offers low conductivity and high energy-efficiency properties for your home and you'll never need to paint or stain your windows.
