Two Approaches,
Infinite Possibilities

Whether your project demands the flexibility of stick-built assembly or the speed of pre-fabricated unitized panels, our curtain wall systems deliver uncompromising performance and aesthetics.

Stick-Built Curtain Wall

The traditional and most versatile curtain wall system. Aluminum mullions and transoms are assembled on-site, with glazing infill installed progressively. Ideal for complex geometries, phased construction, and projects where crane access is limited.
Mullion Depth
2.5″ to 8″
Glazing Infill
1″ to 2″ IGU
Wind Load
Up to 200 psf
Thermal Break
Polyamide 66
Maximum design flexibility for irregular facades
Lower shipping costs — components are knocked down
Easier to accommodate field adjustments

Unitized Curtain Wall

Pre-fabricated interlocking panels manufactured in our controlled facility and craned into place on-site. Dramatically reduces installation time, improves quality control, and enables rapid enclosure of high-rise structures.
Panel Sizes
Up to 5′ x 12′
Factory Glazed
100% Pre-Glazed
Install Rate
50+ Panels/Day
Interstory Movement
±1.5″ Vertical
Superior quality control in factory conditions
Rapid installation — building enclosed in weeks
Reduced on-site labor and weather dependency

Hybrid & Custom Solutions

Complex projects often demand a tailored approach. We engineer hybrid systems combining stick-built and unitized methodologies, structural silicone glazing, point-supported glass, and custom extrusions for architectural landmarks.

FAQ

Curtain Wall Questions

What is the difference between stick-built and unitized curtain wall?
Stick-built curtain wall is assembled piece-by-piece on-site — mullions and transoms are installed first, then glazing is fitted into the frame. It offers maximum design flexibility and is ideal for complex geometries. Unitized curtain wall consists of pre-fabricated panels manufactured in a factory, then craned into place and interlocked on-site. Unitized systems install 3-4x faster, offer superior quality control, and reduce weather dependency — but require earlier design finalization and crane access.
What wind loads can your curtain wall systems withstand?
Our standard curtain wall systems are engineered for wind loads up to 200 psf (pounds per square foot), equivalent to approximately 280 km/h wind speeds. For high-rise towers in downtown Toronto and waterfront locations exposed to higher wind pressures, we engineer reinforced mullion sections and anchorage systems. All designs are reviewed and stamped by licensed professional engineers in Ontario, with structural calculations provided for permit submission.
Do you provide shop drawings and engineering stamps?
Yes — comprehensive shop drawings, fabrication drawings, and structural calculations are included with every curtain wall project. Our in-house engineering team produces 3D modeled drawings showing every mullion, transom, anchor, and gasket detail. All structural calculations are reviewed and stamped by a licensed Professional Engineer (P.Eng) registered in Ontario. We also provide thermal modeling, condensation analysis, and acoustic performance reports as required.
What glazing options work with your curtain wall systems?
Our systems accommodate virtually all glazing types: single, double, and triple insulated glass units (IGU) from 1″ to 2″ overall thickness; laminated safety glass with PVB or SGP interlayers; Low-E coated glass for solar control; ceramic frit and opacified spandrel glass; fire-rated glass for rated assemblies; and even electrochromic smart glass. We work with major glass suppliers including Guardian, Pilkington, and Vitro to specify the optimal glazing package for your performance requirements.
What is your typical lead time for curtain wall projects?
Lead times vary by project complexity and system type. Stick-built systems typically require 8-12 weeks from approved shop drawings to first delivery. Unitized systems generally need 12-16 weeks due to the factory assembly process. Custom extrusion dies add 4-6 weeks for die design and approval. We recommend engaging our team during the design development phase to align fabrication schedules with construction milestones. Rush programs are available for time-sensitive projects.
