Winhoff — Trusted Fenestration

(A)Precision & craftsmanship

Precision in every detail.

Winhoff fabricates aluminum window and door systems by combining advanced machinery with skilled hand finishing — applying European engineering to Canadian performance requirements.

Cut by machine to consistent lengths and angles. Fitted by hand with hardware, seals and glass. Built from aluminum — strong enough for slender frames, durable in demanding climates.

01 — Machine precision

Measured in millimetres.

Automated cutting and machining give profiles consistent lengths, angles and preparation for hardware — the foundation for frames that close accurately and seal evenly.

02 — Skilled finishing

Finished by hand.

Hand finishing and assembly bring the details together: hardware, seals and glazing fitted with care, so each window and door looks and works as intended.

03 — Materials that last

Aluminum, broken thermally.

Aluminum is strong enough for slender frames and large glass, and durable in demanding climates. Thermal-break technology and double or triple glazing options address the comfort Canadian buildings require.
