Automated & Prefabricated Open-Frame Wood Panel System.
Factory built structural panels that cut framing time by up to 50%. Developed to include wall, floor, and roof panels, complete with insulation, cladding, air barrier, and in-house European technology windows and doors. Built off-site to reduce trades, waste, and job site complexity, while delivering a weather tight envelope in days.
Prefabricated Aluminum Window Wall Systems. Installed in Days.
Non-combustible aluminum wall systems with integrated high-performance glazing, insulation, thermal breaks, and weather barrier. Constructed off-site to deliver faster enclosure, higher energy performance and fewer on-site trades. Built to meet high-performance energy targets including Net Zero and Passive House.
Who We Build For
Builders, Developers & Framers
Designed for repeatability and speed, we simplifies the building envelope for high-density projects. With no on-site framing, studs, or embeds required, installation is quick and coordinated for just-in-time delivery. Lightweight aluminum framing and drywall-ready finishes reduce labour complexity while supporting a broad range of cladding systems.
Owners & Investors
We deliver a faster path to occupancy. Its unitized prefabricated design reduces construction timelines, mitigates cost overruns, and ensures consistent thermal and structural performance across the building envelope. With reduced site risk and fewer delays, our panel and wall products supports faster returns and better operational efficiency.
Architects & Designers
We support a wide range of facade finishes, including ACM, terracotta, and cementitious panels, while meeting stringent performance standards for air, water, thermal, and seismic. The system’s prefabricated approach allows for early coordination, reduces detailing conflicts, and aligns with LEED v4.0, Passive House, and Toronto Green Standard requirements.
Vertically Integrated Building Envelope Solutions
Redefining off-site manufacturing through connected expertise.
Backed by the Triumph Group of Companies with 37+ years of experience, PrimeFab is part of a vertically integrated network, delivering full building envelope products and solutions across Ontario. That means fewer delays, better coordination, less third-party procurement and a self-sufficient model that sets us apart in the off-site manufacturing space.

A Better Process
Design
Design assist allows layouts to be optimized for panelization. Our team supports you through coordination with the latest manufacturing software to create detailed shop drawings that align with your project goals.
Off-Site Manufacturing
Our wood and aluminum panel systems are fabricated in semi-automated facilities, using the latest in European manufacturing systems, which bring consistency, quality control, and predictable timelines to every job.
Logistics
Our shrink-wrapped panels are delivered using custom, industry-first logistic processes that facilitate fewer shipments, less on-site delivery traffic and faster assembly.
Installation
Our racking platforms are designed to be on-site prior to installation, which allows for simplified sequencing, reduced disruption, and risk. Platforms can be dropped in specific locations to avoid lengthy trailer unloading times.
37+ years of envelope solutions.
Why PrimeFab
PrimeFab combines proven residential and ICI development experience, advanced building envelope manufacturing, innovative prefabrication technology, and a strong understanding of how to streamline the construction process.
