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.

Red-walled room with custom windows with prairie grids

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. Our beveled mainframe and sash design creates an elegant exterior appearance. Plus, UltraMaxx provides a wide range of design options to complement your home’s interior.

UltraMaxx windows help to lower energy costs, provide maintenance-freedom and also increase the property value of your home, and are covered by our impressive Lifetime Limited Warranty.*

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

A custom project from our gallery

Before and after: large drafty windows on a sided home, replaced with a custom configuration of transoms over oriel-style units

Custom oriel-style windows with prairie grids

Before: These large multiple units were drafty and lacked energy-efficiency. Our client's view was obstructed and the home got lost in the neighborhood, so our client was open to suggestions on an aesthetically appealing but high-efficiency alternative. After: This custom-designed configuration completely changed the look of this home and made it an appealing eye-catcher in the neighborhood. Our client opted for smaller transoms above oriel-style units with encased prairie grids to maximize the view. All units have the triple-pane package for high-efficiency performance.
