The trusted choice. Canadian made.
Sliding & Stacking Patio Doors
Sliding patio doors operate with two glass panels: one slides horizontally along a track while the other remains fixed. Simple, reliable, and practical for any room. Stacking patio doors go further, with multiple panels that slide and stack behind one another along a track. One end panel stays fixed while the others open in either direction, creating wider openings and greater flexibility. Both door types maximise natural light, connect indoor and outdoor spaces, and suit any home design.

Sliding & Stacking Patio Doors Features
Built for Canadian Climates
Canadian winters demand more than a standard patio door. Our sliding and stacking doors are built with double or triple pane glass, thermal breaks, reinforced seals, and Low-E coating to keep your home warm in winter and cool in summer. The result is lower heating and cooling costs year round, and fresh airflow on demand when you open them.
Maximize Interior Space
Sliding and stacking patio doors frame wide, uninterrupted openings that connect your indoor and outdoor spaces. Open them fully for unrestricted access or partially for a controlled breeze. Full control over how much space, light, and air you let in.
Enhanced Interior Light
Large glazed panels maximise natural light throughout your home. In the middle of a Canadian winter, the difference between a dim room and a bright one matters. Our Low-E coating brings in the light while keeping the cold out.

Double Pane vs
Triple Pane Windows
Glass panes are the most vulnerable surface for energy loss through heat transfer. In Canadian climates, a minimum of two panes is necessary on every sliding and stacking patio door. In regions with prolonged low winter temperatures, three panes provide greater insulation and thermal performance.
