How it works
Panels that slide and tuck behind one another
Each panel runs on its own track. Open one like a regular slider, or push the whole run to one side and the wall is gone.
Configurations
Three to six panels, stacking your way
One panel stays fixed as the pocket the others slide behind. The more panels, the bigger the share of the wall that opens.
Three panels
Two slide, one fixed: two thirds of the opening clears.
Four panels
Three slide behind one: three quarters clear.
Five panels
Four slide behind one: four fifths clear.
Six panels
Split from the centre, three each way: five sixths clear, opening like a curtain.
Every run is measured at your home and built to the opening. Openings wider than a standard patio door are common; the estimator confirms the structure and the header with you.
Compare
Stackable, bi-folding or sliding: which patio door fits your opening?
Same triple-pane glass, same frames, same crews. The difference is how much of the wall opens and where the panels go when it does.

Stackable

- Up to five of six panels stack behind one: almost the full wall
- When open
- The stack stays in the wall plane; nothing projects inside or out
- Threshold
- Low threshold, one track per panel
- Daily use
- Open one panel like a slider, or the whole run
- Frame and glass
- uPVC or hybrid aluminum, triple-pane double Low-E, multipoint locks
- Best for

Bi-folding

- Frame and glass

At a glance
What every stackable door comes with
Built for a Montreal winter
A wall of glass that still holds the heat in February
Thermally broken frames and triple-pane, double Low-E glass keep the room warm along the whole run, not just in the middle. The sill drains outward so melting snow leaves the way it came.
Every panel is measured at your home and built for the opening. Our own crews install, seal and finish the interior; nothing is subcontracted.
After the install, one number reaches a service department that answers. That is the same promise as on every window we sell.
