Norstar Windows & Doors Ltd. delivers integrated, commercial-grade fenestration services designed specifically for developers, general contractors, and institutional procurement teams.
By housing engineering design-assist, CNC aluminum profile fabrication, state-of-the-art insulated glass assembly, and certified jobsite installation within one cohesive organization, we remove the multi-trade friction points that lead to envelope failures, installation delays, and cost overruns.
| Scope Area | Delivery Details |
|---|---|
| Design & Engineering | BIM modeling, structural load calculations, thermal simulations, and PE-stamped shop drawings. |
| Manufacturing | CNC precision extrusion cutting, robotic silicone corner crimping, and insulated glass unit staging. |
| Installation Services | Full rough-opening preparation, perimeter air/vapor barrier tie-ins, crane logistics, and structural anchoring. |
| Retrofit Programs | Occupied multi-family sequencing, hazardous material containment coordination, and same-day closure. |
| Quality Verification | On-site ASTM E1105 field water penetration and AAMA 501.2 dynamic water spray testing. |
Engineered to fulfill demanding thermal performance targets (SB-10 / ASHRAE 90.1), acoustic isolation criteria, and rigorous life-safety codes.
Early-stage collaboration with architects and consultants to optimize frame depths, thermal breaks, deflection criteria, and facade interfaces before budgeting lock-in.
Computerized profile processing, multi-chambered polyamide thermal isolation strut assembly, and automated corner joins built in our climate-controlled Ontario plant.
Certified, site-supervised field installation crews equipped for multi-story rough opening set-ins, sub-sill flashing tie-ins, sealants, and exterior perimeter membranes.
Turnkey fenestration renewal for aging high-rise towers, multi-family complexes, and commercial properties, engineered to safeguard resident comfort with minimal interior downtime.
Integrated balcony glass and picket railing fabrication engineered to interface directly with window walls and structural slab edges without chemical compatibility conflicts.
Dedicated quality management teams conduct rigorous pre-handover inspections, field water chamber tests, diagnostic air leakage verification, and warranty certification.
Procurement directors and general contractors trust Norstar because every engineered system undergoes empirical verification to exceed building code thresholds.
Heavy commercial & architectural terrace ratings engineered for high wind load pressures and coastal exposure.
Low overall U-factors achieved through multi-chamber thermal breaks and triple-glazed argon Warm-Edge spacers.
High water-tightness test pressure thresholds preventing moisture egress under extreme meteorological events.
Zero split-liability claims between material manufacturer and jobsite installers throughout product warranty cycles.
A methodical, code-compliant delivery sequence guaranteeing on-schedule structural delivery, water-tight envelope integrity, and cost certainty.
Architectural specification assessment, thermal modeling, preliminary structural sizing, and value engineering proposals.
Preparation of detailed installation drawings, anchor calculations, perimeter membrane tie-ins, and extrusion die confirmations.
In-house CNC machining, corner crimping, gasketing, and factory glazing inspection inside our Canadian facility.
Systematic site logistics, union crew mobilization, structural anchoring, sub-sill drainage, and membrane integration.
Diagnostic field water tests, punch-list sign-off, operation and maintenance manuals, and formal warranty packages.
A benchmark comparison table designed to help commercial procurement officers and site superintendents evaluate envelope trade capabilities.
| Service Phase | Core Technical Deliverables | Standards & Testing Reference | Risk Mitigation Value |
|---|---|---|---|
| Design & Value Assist | BIM coordinated shop drawings, thermal bridging simulation, structural wind load analysis. | ASHRAE 90.1, SB-10, CSA S157 | Eliminates site geometry clashes, unbudgeted change orders, and thermal envelope under-performance. |
| Extrusion & Glazing Fabrication | Polyamide thermal strut assembly, CNC miter joints, dual-sealed silicone IGU integration. | NAFS / CSA A440, IGAC/CGSB 12.8 | Eliminates factory batch defects, sealant degradation, and internal argon leakage. |
| Rough Opening Site Prep | Laser leveling, sub-sill drainage panning, end-dam sealant, self-adhered vapor barrier flashing. | ASTM E2112, CSA A440.4 | Prevents water migration at window-to-wall interfaces, the primary root cause of building leaks. |
| Field Glazing & Rigging | Floor-by-floor staging, high-elevation crane lifting, precision expansion joint placement. | OSHA, Ontario MOL Safety Regs | Protects on-site trades, prevents glass stress fractures, and accommodates building live-load deflections. |
| Retrofit Envelope Upgrades | Suite-by-suite removal, containment barriers, rapid perimeter anchor reset, daily weather-seal. | CAN/CSA-A440.2 Energy Rating | Protects interior occupant assets from rain exposure while modernizing acoustics and thermal comfort. |
Commercial Insight: Selecting a contractor with certified in-house installation eliminates finger-pointing between separate glass fabricators and framing subcontractors.
Norstar provides complete, single-source fenestration solutions including architectural design-assist, thermal calculations, shop drawings, CNC aluminum profile fabrication, in-house glazing, field installation, and occupied building retrofits across multi-family, commercial, and institutional projects.
Dividing supply and installation between multiple subcontractors frequently leads to split liability when water penetration or structural deflections occur. Norstar's unified approach means one experienced firm assumes total legal and performance accountability for the entire opening.
We utilize a disciplined suite-by-suite workflow. Our crews mask and protect interior living spaces, remove the existing frame, install the new thermally broken system, complete exterior tie-ins, and ensure complete weather-sealing before the end of each working day.
Headquartered in Stoney Creek, Ontario, we service commercial and multi-residential projects across Canada and support overseas developers and procurement managers requiring North American code-certified commercial fenestration packages.
We provide full closeout documentation packages containing factory quality check sheets, mill finish certifications, NAFS/AAMA laboratory testing records, structural engineering stamps, on-site ASTM field water test logs, and comprehensive product warranties.
Collaborate with our engineering and estimating departments for design-assist review, structural sizing, budgeting analysis, and field installation scheduling.
