(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.
