Windows
HORIZON
Slim-frame windows engineered for big views and hard winters. Made to order, installed by certified crews, and backed for life.
Duo-Tilt lock system
One hardware piece handles three actions — lock, unlock, and tilt. The hidden tilt latch means an air-tight seal and a stronger corner weld on the meeting rail.
Warm-edge spacer glazing
Intercept U-channel warm-edge spacer with Low-E argon glass creates a thermal barrier that cuts heat loss; stainless spacer available as an upgrade.
Fusion-welded frame and sash
Every frame and sash corner is fusion welded — strong and gap-free, never compromised by knock-outs. Optional Innergy rigid thermal reinforcements add support and insulation.
True Position ½" balance
Springs travel with the sash, so windows glide with far less friction and noise. Continuous over/under interlock and a sloped one-piece sill stop air and water infiltration.

Styles
Seven shapes, one system
- Double hung
- Two operable sashes move independently and tilt inward for cleaning from inside — ideal for upper-story glass and the most common choice on Midwest homes.
- Casement
- Side-hinged sash cranks outward on a multi-point lock for the lowest air-leakage rate in the line and excellent natural ventilation.
- Glider
- Sashes glide horizontally on a track for unobstructed views and wide openings where swing space is limited.
- Awning
- Top-hinged sash opens outward from the bottom, so it vents in the rain. Pairs well above picture units and in baths.
- Bay & bow
- Projection units that add floor space — angular bay with a large picture center, or curved bow lines, factory assembled with insulated head and seat boards.
- Garden
- A 90° box bay with a picture window in the center — light on three sides plus glass shelving for plants.
- Patio doors
- Two, three, or custom panel sliders with a foot-operated deadbolt, sloped aluminum-reinforced sill, stainless roller track, and zinc-plated tandem rollers.
