Back to double-hung window selection
There's a unique feeling of confidence that comes from knowing you have chosen UltraMaxx® Windows from Alside. They are not only beautiful; their heavy-gauge, fusion-welded vinyl sash and mainframe structure makes them incredibly strong and durable. Years of operation and harsh weather won't diminish their quality or performance.
Multi-Chambered sash and mainframe create insulating air spaces for thermal efficiency.
All UltraMaxx Double-Hung and Sliding Windows feature the Triton Locking System. Located at the meeting rails, this heavy-duty cam lock and keeper fit tightly together when fully engaged for added security.

ClimaTech High-Performance Insulated Glass Packages
ClimaTech insulated glass package combines multi-layered low-emissivity (Low-E) glass, argon gas and the PPG Intercept Warm-Edge Spacer System. ClimaTech is up to 40% more energy-efficient than single or clear insulated glass systems.
Winter Energy Savings: Low-E insulating glass reduces heat loss by reflecting warm air back into your home.
Summer Energy Savings: Low-E helps block unwanted solar heat penetration to help reduce air-conditioning usage.
