About · The range, the team
Supplied, installed, and warrantied
by one team.
Cadence supplies premium windows and doors. Every unit is certified to CSA or the Passive House Institute, fitted with German precision hardware, available supply-only or turnkey (supply and installation), at a highly competitive price.
Founded in Montréal,
2025.
Cadence was founded in 2025 by two partners with complementary expertise in construction estimation, real estate development, and manufacturing. Clients work directly with the founders, who manage specification, procurement, and installation.
We work by appointment, in Montréal and on your projects across Canada, from specification to final inspection.

Three principles.
One certified range.
Our principles are short, and we hold to them on every drawing set we touch.
-
Precision.
Every U-factor, ER, and pressure rating on this site is verified to CSA A440.2:19 or the Passive House Institute component standard. The certified value is the value we quote.
-
Continuity.
A single project lead manages the detailing, the site survey, and the final inspection. You work with one point of contact from quotation through completion.
-
Focus.
Cadence is a focused product line, not a catalogue. Three certified lines, Hybrid, Alu, and Passive, each selected because it earns a place in a Canadian building envelope.
Cadence turns
a drawing set
into an envelope.
Cadence offers a complete range of windows and doors, organized into three product lines: Hybrid (aluminium-clad UPVC), Alu (full aluminium), and Passive (Passive House certified). Every project is managed end to end, with each component's manufacturer warranty consolidated by Cadence as your single point of contact.
Cadence is a turnkey supplier. We recommend the range, produce the shop drawings, supply to purchase order, deliver to site, and install. A single point of contact manages each project, from initial design to final inspection.

Frequently asked questions.
Every answer references a CSA or Passive House standard, a published value, or a deliverable that already exists elsewhere on this site.
-
Are Cadence windows certified for use in Canadian code-compliant envelopes?
Yes. Every Cadence product line is CSA certified and energy-rated to the applicable Canadian standards. Cadence Passive also holds a Passive House Institute component certificate. -
What U-factors should I use in my energy model?
Use the CSA-published values on the product datasheets. Each glazing build-up has its own certified U / SHGC / VT / ER row, the lowest U we publish is 0.75 W/m²·K on the Cadence Passive side-hinged door. The datasheets list every certified variant. -
Where do you work, and what's the lead time?
Cadence supplies and installs across Canada. Typical lead time is 10 to 14 weeks following shop-drawing approval. -
Do you supply hardware as a separate line item?
No. German Roto hardware is fitted at the factory and warrantied with the frame for ten years. Cadence quotes the assembled, certified unit, not parts. -
What technical data is public before I contact sales?
The CSA-certified performance data, U-factors, Energy Ratings, and NAFS grades, is public on this site, no form, no email gate. Cadence doesn't publish CAD or BIM files; project-specific jamb, sill, and head details are produced as shop drawings once you're engaged. -
Is Cadence available for commercial or multi-unit projects?
Yes. All three lines are CSA Performance Class CW-PG40 through PG70 depending on the product, with type-tested sizes up to 3657 × 1880 mm. Talk to the team about specification support for commercial scopes. -
What hardware brands ship on a Cadence frame?
Roto (Germany) multi-point hardware, backed by a ten-year warranty. AkzoNobel powder-coat paint, AAMA-compliant (2603, 2604 or 2605 per project), and Remmers water-based lacquer on the interior side of the Passive line.
