Ultra-Premium, Custom-Made Windows

The multi-chamber design of the UltraMaxx Window helps trap dead air to produce an effective insulating barrier, while fusion-welded frame and sashes provide superior structural strength and create a permanent barrier against air and moisture infiltration.

A special multi-layer weatherstripping and a superior sash interlock system offer additional barriers to air infiltration, adding up to greater energy savings – and lower utility bills.

UltraMaxx’s Intercept®Warm-Edge Spacer System with high-efficiency insulated glass creates an effective barrier that helps to prevent heat loss during winter and heat gain during the hot summer months.

Premium raw materials form the extrathick walls of UltraMaxx’s sturdy frame and sashes, and the quality construction ensures that they won’t rot, swell, split, corrode or pit. It’s tough, durable and other than an occasional washing, requires minimal maintenance.

To ensure easy opening and closing of the UltraMaxx Window, the constant force balance system and heavy-duty operating hardware will continue to operate perfectly, even after decades of regular use. A full-capture sill enhances protection from the elements while maintaining the timeless detailed appearance characteristic of double-hung windows. Beveled mainframe on double-hung, sliding and casement windows provide a finished appearance complementing every home’s style.
