Features and Benefits of Alside Ultramaxx

  • 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 Alside 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 Alside Ultramaxx windows free from accumulation of water and debris
