Features & Benefits

A. Fusion-welded frame and sashes provide superior structural strength and create a permanent barrier against air and moisture infiltration

B. The multi-chamber design of the UltraMaxx Window helps trap dead air to produce an effective insulating barrier

C. Quad 4 weatherstripping at the header and sill adds greater protection from the element

D. 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

E. The Intercept Spacer System helps reduce conducted heat loss through the window and is better at retaining insulating gas than many conventional designs

F. Triple-barrier weatherstripping between the sash and jamb for superior protection from air and water infiltration

G. Full-capture sill channels water to the exterior – keeping your windows free from debris and water accumulation

H. Optional ClimaTech insulated glass packages available. Consult your window professional for the optimal glass package required for your home and climate zone
