FRP passive house windows for Canadian projects
Pultruded fiberglass window frames for Canada's Passive House, net-zero, and step-code buildings — PHIUS-aligned PHI Cert 2491wi03 (U_w 0.78), CSA A440 / NAFS performance, and not caught by Canada's 25% surtax on Chinese steel and aluminum.
Passive-house-grade fiberglass windows — without the aluminum surtax
Canada is pushing every new building toward net-zero-energy-ready by 2032 — through the BC Energy Step Code, the Toronto Green Standard, the National Building Code / NECB tiered energy paths, and a growing book of PHIUS and Passive House Canada certified projects. Those targets are won or lost at the window: a thermally broken aluminum frame simply cannot reach the U-factor the upper steps demand without oversized glazing.
F1 Composite’s pultruded FRP fenestration solves the thermal problem at the frame. The whole frame is intrinsically insulating — fiberglass thermal conductivity ≈ 0.3 W/m·K versus aluminum’s 160 — so our 90-series reaches a whole-window Uw of 0.78 W/m²·K (U-factor ≈ 0.14 Btu/h·ft²·°F) with no metallic thermal-break path to fail in a Canadian winter.
Then there is the cost story Canadian buyers are not being told. Since December 26, 2025 Canada’s 25% surtax covers steel and aluminum goods with Chinese content — and steel-framed doors and windows specifically. Pultruded FRP is a glass-fiber composite, not steel or aluminum, so it is not caught by the surtax. Where a Chinese-content aluminum window now lands with a 25% surtax, an F1 FRP window does not.
For Passive House projects: our 90 Series GFRP-PU window frame holds PHI Component Certificate 2491wi03 (Uw = 0.78 W/m²·K, phB class) — recognized across PHIUS and Passive House Canada projects. Drop-in replacement for aluminum or fiberglass frames on any certifying building, with architectural-grade AAMA 2604 / 2605 powder coating in any RAL color. Normal MFN duty + 5% GST are quoted inline DDP — no surprise on landed cost.

Send us a drawing or section sketch, the target quantity, and the delivery province. F1 will provide complete DDP pricing in CAD or USD, with the MFN duty and 5% GST itemized, plus the HS classification and estimated delivery date to your jobsite. The 25% surtax does not apply to FRP.
Production in 4–6 weeks · certification package
F1 manufactures the profiles on its own pultrusion lines. The shipment includes PHI Component Certificate 2491wi03, the NAFS test report, a report from an AAMA-listed coating applicator, and the CSA A440.2 / NFRC simulation.
Ocean freight and DDP delivery
Ocean transit takes 14–20 days to Vancouver or Prince Rupert and 26–32 days to Montreal or Halifax. The total lead time from purchase order to jobsite is 8–12 weeks. DAP delivery is available from the port of entry to Calgary, Toronto, and Ottawa.
Frequently Asked Questions
Are FRP windows from China subject to Canada's 25% surtax?
No. Canada's surtax orders apply to steel and aluminum goods containing Chinese-melted or -cast metal (in force since July 31, 2025) and were extended to steel derivative goods — including steel-framed doors and windows — effective December 26, 2025. Pultruded FRP (fiberglass-reinforced polymer) fenestration is a glass-fiber composite, not steel or aluminum, so it is not covered by these surtax orders. Aluminum window systems with Chinese content can be caught by the 25% surtax; FRP is not. The normal MFN customs duty (classified under HS 3926.90 / 7019) and 5% GST still apply and are quoted inline in our DDP Canada price — no surprise on landed cost.
Which Canadian standards are F1 Composite FRP windows tested to?
Performance to NAFS — AAMA/WDMA/CSA 101/I.S.2/A440-11 with the Canadian Supplement CSA A440S1 (air, water, wind, forced-entry, operating force). Energy performance per CSA A440.2 / A440.3 simulation and NFRC 100 on request, so the frames carry an ENERGY STAR for Canada-comparable U-factor. Thermal certification is the PHIUS-aligned PHI Component Certificate 2491wi03 (U_w = 0.78 W/m²·K ≈ U-factor 0.14 Btu/h·ft²·°F, phB class) — recognized across PHIUS and Passive House Canada projects nationwide.
Do F1 FRP windows meet the BC Energy Step Code and Toronto Green Standard?
Yes — comfortably. The BC Energy Step Code and Zero Carbon Step Code drive new buildings to net-zero-energy-ready by 2032, and upper steps require window U-factors well below 0.22 Btu/h·ft²·°F (≈ 1.25 W/m²·K). Our 90-series FRP frame at U_w 0.78 W/m²·K (U-factor ≈ 0.14) clears Step 4/5 window targets and the Toronto Green Standard Tier 2–4 thermal envelope criteria with margin, because the entire pultruded frame is intrinsically insulating (≈ 0.3 W/m·K) with no aluminum thermal-break path to fail in cold climates.
What are the lead times and shipping options to Canadian ports?
Standard schedule from PO: 4–6 weeks production + sea freight of 14–20 days to Vancouver / Prince Rupert (West Coast) or 26–32 days to Montreal / Halifax (East Coast). Total PO-to-jobsite is typically 8–12 weeks DDP. For inland destinations (Calgary, Toronto, Ottawa) we deliver DAP via rail/truck from the port of entry. Urgent samples or replacement parts ship air freight ex-Shanghai to any major Canadian hub in 4–6 days at premium cost.
Can F1 supply CAD-priced, DDP quotes for Canadian projects?
Yes. We quote DDP to your Canadian jobsite in CAD or USD, with MFN customs duty and 5% GST itemized so your QS sees the full landed cost up front. We classify under HS 3926.90 or 7019 depending on configuration, ship with our Canadian customs broker handling clearance, and provide UFLPA-grade supply-chain traceability documentation with every shipment. Provincial PST/HST handling is confirmed per delivery province at PO acceptance.
How does F1's FRP compare to Cascadia, Inline, and Innotech fiberglass frames?
F1 matches the thermal performance of North American fiberglass-frame specialists (U_w to 0.78 W/m²·K, no thermal break) and adds a PHIUS-aligned PHI component certificate plus AAMA 2604/2605 architectural finishes in any RAL color. The difference is sourcing economics: F1 holds 800+ existing die sections and pultrudes on its own lines (5 bases, 370 lines), so engineered fenestration profiles often skip new tooling, and — unlike aluminum systems — FRP is not exposed to the 25% Chinese-content surtax in Canada. For projects needing a Canadian fabricator, F1 supplies profiles into a fabricator-partner assembly model.
