Prime Panels

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.

Featured Project

PrimeFab delivered a complete 2,100 sq ft Muskoka home in just four days, cutting the traditional build time by more than two weeks.

This project served as both a residential build and a live R&D environment, allowing our team to test load tolerances, optimize WRB application, and refine storage and logistics processes. The full structural envelope was delivered with pre-installed windows, plus interior partitions, subfloors, and roof panels, all assembled on site with remarkable efficiency. It’s a powerful example of what’s possible when innovation and execution work hand in hand.

A Better Process

From designs to installation the path is clear.

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.

Prime Panels

Prefabricated wood panel system.

PrimePanels include wall, floor, and roof panels, complete with insulation, cladding, air barrier, and in-house European technology windows and doors. Our panel system is designed for fast assembly, reduced on-site trades, and consistent quality from the manufacturing factory to installation site.

Prime Walls

Prefabricated aluminum window walls.

Engineered and tested to meet the highest code and energy standards, PrimeWalls combine structural aluminum, insulation, thermal breaks, weather barrier, windows, and doors into a non-combustible, patent-pending prefabricated unit. Integrated high-performance glazing completes this system, designed to accept finishes like stone, metal, and brick.

Prime Spaces

Prefabricated, panelized units designed for modular delivery.

PrimeSpaces are pre-approved or proprietary plans that can be panelized for modular units. We’ve designed these to be scalable individual models or volumetric. They offer flexibility for interior/exterior finishes and floor plan layouts. PrimeFab can also work directly from CMHC Housing Design Catalogue plans, transforming standardized designs into build-ready panelized systems for faster, more predictable construction.

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.

We partner with our clients on design, delivery and installation. By offering value-engineered solutions that improve project efficiency and support scalability, PrimeFab makes you build smarter.
