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. And they offer superior resistance to the elements and air and water infiltration.

Features and Benefits

Fusion-welded frame and sashes provide superior structural strength and create a permanent barrier against air and moisture infiltration
The multi-chamber design of the UltraMaxx Window helps trap dead air to produce an effective insulating barrier
Quad 4 weatherstripping at the header and sill adds greater protection from the elements
Heavy-duty SteelForce™ reinforcement is placed within the sashes at the meeting rails to ensure extra protection at this very critical and often used location

The Intercept Spacer System helps reduce conducted heat loss through the window and is better at retaining insulating gas than many conventional designs
Triple-barrier weatherstripping between the sash and jamb for superior protection from air and water infiltration
Full-capture sill channels water to the exterior – keeping your windows free from accumulation of water and debris
Optional ClimaTech insulated glass packages available. Consult your window professional for the optimal glass package required for your home and climate zone
