About · The line, the studio, the team
Supplied, installed, and warrantied
by a single team.
Cadence supplies one comprehensive window and door range, organised into three product lines, Hybrid, Alu, and Passive. Every frame is CSA or Passive House Institute certified, fitted with German precision hardware, and delivered as a single warrantied unit managed across Canada.
Cadence translates
a drawing set
into an envelope.
Cadence is a full-service supplier. We recommend the line, produce the shop drawings, supply to your purchase order, ship to site, and install, Hybrid, Alu, Passive, with each component's manufacturer warranty consolidated through Cadence as your single point of contact.
Every Cadence frame is CSA or Passive House Institute certified, fitted with German precision hardware, and warrantied for a minimum of ten years on glass, aluminium, hardware, and finish.
Each phase carries the same intent: to verify before we quote, to draw before we build, and to stand behind every envelope we put our name on.
Three principles.
One certified line.
Our principles are short, and we hold ourselves to them on every drawing set we touch.
- /A
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.
- /B
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.
- /C
Restraint.
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.

The questions with verifiable answers.
Every answer references a CSA or PHI 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 tested to AAMA/WDMA/CSA 101/I.S.2/A440-17 with the matching CSA A440S1:19 Canadian supplement, and energy-rated to CSA A440.2:19. Cadence Passive also holds a Passive House Institute component certificate (class phB, Uw 0.79 W/m²·K). -
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 0.77 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 12 to 17 weeks following shop-drawing approval and field measurements. Region-specific lead times are published in the builders' resources. -
Do you supply hardware as a separate line item?
No. German Roto, Siegenia, G-U, and Hoppe hardware is fitted at the factory and warrantied with the frame for ten years. Cadence quotes the assembled, certified unit, not parts. -
Can I draw with Cadence before contacting sales?
Yes. Revit, ArchiCAD, and DWG details for every line are public on the architects' resource page, no form, no email gate. The CSA U-factor and Energy Rating tables sit alongside them. -
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 studio about specification support for commercial scopes. -
What hardware brands ship on a Cadence frame?
Roto, Siegenia, G-U, and Hoppe (Germany), Maco (Austria), Storo (Italy), Kerssenberg (Germany), backed by ten-year warranties. Akzo Nobel powder coatings (AAMA tested) and Remmers water-based wood lacquer on the Passive line. -
How do I get a physical sample?
Request one from the contact page. Cadence ships a sample kit, frame profile, glazing build-up, Roto hardware, to your studio for sign-off before any cost is committed. Or visit the showroom at 3901 av. Bannantyne, Verdun, by appointment.
