Frame a better view.
Precision-crafted aluminum windows, doors and architectural glazing systems. European engineering, applied to Canadian performance requirements.
(01)Trusted fenestration
Every Winhoff system starts with aluminum strong enough for slender frames and large glass — then it's finished by hand with precision in every detail.

(02)Four system families
Four ways to frame a space.
Point at a family to open it. Each one is a different answer to how a room meets the outdoors.
01Windows & Doors

Windows & Doors
Thermally broken casements and statement doors — from everyday windows to pivot entrances up to 4200 mm tall.

(03)GS142 · Lift & slide
Open up the possibilities.
Seamless living, inside and out — made possible by a system that lifts heavy glass before it moves. Scroll to operate the model.
01 — Lift
Expansive views
Turn the handle and the sash rises off its seals. GS142 handles moving sashes up to 500 kg — and fixed sashes up to 1000 kg — so one opening can span much of a wall.
02 — Slide
Effortless movement
Lifted clear of the seals, the heavy sash glides along its track instead of dragging across them.
03 — Lower
A closer connection outdoors
Turn the handle back and the sash settles onto its seals. Monorail, multirail, double or triple tracks and a pocket solution let the glass disappear the way the plan needs.

(04)Precision in every detail
Precision, made visible.
Take a thermally broken frame apart. Turn it, separate the layers, switch between double and triple glazing — and see why the break matters.

Illustrative model to explain how a thermally broken frame is built — not the exact geometry of any Winhoff profile. The thermal view is a concept sketch, not test or simulation data.

(05)The collection
Eleven systems. One standard of precision.
(06)Applications
Designed for the way a space opens.
01 — GC74
A statement entrance.
Pivot doors turn on an axis set in from the jamb, so very wide, very tall leaves swing with surprising ease. Double-action doors swing both ways.

- Sash height, up to
- mm
GC74 catalogue values; sizes subject to project and configuration review.

02 — Curtain walls
Transparency at façade scale.
GF60, GF50 and the hidden-vent GF60HV form continuous glazed façades with thermal-break engineering and a transom drainage approach.

03 — Glass railings
Nothing between you and the view.
GCR60 and GCR100 hold frameless 17.52 mm or 21.52 mm tempered laminated glass in a base channel — left exposed, or with GCR100, set below the finished floor.

(08)Precision in every detail
Craftsmanship behind the frame.
Winhoff fabricates aluminum systems by combining advanced machinery with skilled hand finishing — European engineering applied to Canadian performance requirements.
