Vacuum insulated glass solves a different problem for each of the four segments that drive Canada's glazing market. VIG Horizon speaks each segment's language, technically, commercially, and bilingually.
Canada's built heritage is extensive — Vieux-Montréal, Ottawa's Centretown, Toronto's Annex and Cabbagetown, Halifax's South End, Victoria's James Bay. Virtually every designated or heritage-listed property in these districts has original window openings designed for single glazing: narrow frame rebates, shallow sash profiles, and structural members that cannot accommodate the 20–28mm total thickness of modern double IGU without significant intervention.
The 3TL+V+3T configuration at 6.2mm total thickness changes this completely. It delivers vacuum insulation performance — U=0.58 W/m²K, sound reduction over 40dB, and no-condensation performance to −70°C — in a profile that fits the glazing rebate of virtually any pre-1946 Canadian sash window frame without structural modification, heritage board objection, or loss of original appearance.
Applies to designated heritage properties in Quebec (Loi sur le patrimoine culturel), Ontario (Ontario Heritage Act), and federal designations under the Historic Places Initiative. VIG Horizon provides compliance documentation in English and French for local heritage authority submissions.
Ontario Step Code Phase 5 · BC Energy Step Code Level 4–5 · Quebec Code de construction (Section 9.36) · Any envelope assembly requiring window U ≤ 0.45 W/m²K
Ontario Step Code Phase 5 requires window assemblies below 0.45 W/m²K. Triple IGU reaches this threshold — but at 32–44mm total thickness, 28 kg/m², and a frame-depth requirement that demands structural accommodation throughout the building. For net-zero builders and Passive House designers, triple glazing is not so much a solution as a constraint that propagates cost and complexity through the entire building system.
The 4TL+V+4T configuration at U=0.40 W/m²K — independently confirmed by TÜV Rheinland (Report CN25TTIK, September 2025) — is the only single glazing unit that clears the 0.45 threshold while remaining at 8.2mm total and 20 kg/m². It requires no deeper frames than conventional double IGU, no additional structural accommodation, and no weight penalty to the window system. For heritage buildings targeting energy performance upgrades, it delivers Step Code compliance without frame replacement.
Premium window manufacturers face a clear market signal: architects are specifying vacuum glass, net-zero tenders are requiring sub-0.45 U-values, and heritage projects demand slim-profile solutions. The response — building a VIG production line — requires vacuum pumping equipment, process engineering, supplier qualification in China, and a QC team capable of monitoring a production process that has very low tolerance for error. For most Canadian window fabricators, this is not a viable investment path.
VIG Horizon eliminates the investment entirely. We supply SGCC-certified, IGCC-certified, fully tempered VIG — produced on Glaston FC500 lines, shipped DDP to your facility — so you can brand, sell, and install a VIG product line with complete Canadian compliance documentation. No equipment, no supplier relationship to manage, no Chinese customs risk, no MOQ.
Supplier qualification · Factory QC monitoring · Customs classification · CBSA documentation · Inland freight coordination · Warranty administration · First-install training · Ongoing bilingual technical support
Commercial building projects and institutional retrofits that want to specify vacuum insulated glass face a sourcing challenge: the technology is proven internationally, but there is no Canadian manufacturer and historically no Canadian entity prepared to attend design team meetings, provide NRC-compliant specification data, coordinate delivery into a project schedule, and handle warranty matters locally after installation. Architects specifying advanced glazing technologies need a local technical counterpart — not a foreign supplier's export department.
VIG Horizon is that entity. We attend design team meetings (Montréal area), provide NRC-compliant U-value data and CAN/CGSB compliance statements in English and French, coordinate delivery with project schedules, and manage all warranty matters in Canada post-installation. The 5mm and 6mm configurations handle curtain wall and high-rise applications up to 1900×2800mm. For large commercial contracts, container volume and project-dedicated supply coordination are available.
Whether you are a heritage glazier in Vieux-Montréal, a net-zero builder on a Step Code 5 project in Waterloo, a premium window brand in the GTA adding a VIG product line, or an architect specifying curtain wall in downtown Vancouver — VIG Horizon is the same one contact, the same 48-hour response, the same certification documentation, the same bilingual service, and the same 15-year Canadian warranty administration.
Complete the specification request form and we'll return documentation tailored to your market segment — heritage, net-zero, manufacturer, or commercial — within 48 hours. In English or French.
