35 Silton — Cannabis Cultivation Cold Storage Built Inside an Existing Facility
The Build
Building cannabis cultivation cold storage inside an existing facility
35 Silton was a build-in-place job: WFE built the cannabis cultivation cold storage envelope inside an existing operating commercial building rather than dropping a prefab unit into an open warehouse. That meant fitting the panel work to the room's real dimensions instead of a catalog default, and building around a structural support column that runs straight through the middle of the build zone, wrapping it into the envelope without compromising either the column or the cold storage seal. The finished rooms run as grow and post-harvest cold storage, where holding temperature and humidity steady matters as much as the seal.
On-Site Build
Built in place, panel by panel.
Every insulated panel measured, cut, and sealed on site by the WFE crew, fitted to the room's real dimensions instead of dropped in as a prefab unit.

Operational, in detail.
The finished envelope as a cannabis grow room: rolling benches, grow-light rails, sealed panel walls.
Rolling-bench cultivation room built inside the existing facility, panel envelope sealed end to end.
WFE-branded coveralls on every worker. The crew that quoted the job is the crew on site.
The cutting station inside the build zone. Panels prepped on site for tight-fit installation.
What's in the Build
Spec'd for the work.
Every component sized for the project's actual load, door-cycle profile, and shift volume. Nothing pulled from a catalogue.
Cannabis cultivation cold storage envelope built inside an operating commercial building, not dropped in as a prefab unit. The finished rooms run as grow and post-harvest cold storage, framed against the existing walls, ceiling, and structural elements of the room.
A building structural support column runs through the middle of the build zone. WFE built the cold envelope around it, wrapping the column with protective sleeving so the cooler integrates cleanly without compromising the building's structure.
4-inch Norbec insulated panels measured and cut on site to fit the actual dimensions of the space. Custom cuts, tight seams, no field gaps. Every panel-to-wall and panel-to-column interface specced for the real geometry, not a catalog default.
WFE-branded coveralls and hoodies on every worker on site. Same team that designed the cold envelope is the team measuring, cutting, setting, and sealing each panel.
Orange Milwaukee work-light tripods staged for visibility inside the cold envelope. Sawhorse for panel cutting, sealant boxes staged, panels stacked against walls ready for placement. The crew runs the site like the install zone it is.
Panel-to-panel seams sealed and the envelope closed cleanly. Floor-to-ceiling white insulated panels finished to a clean interior, ready for refrigeration plant and shelving fit-out.

Outcome
How it landed.
35 Silton went operational as a cannabis cultivation facility, with the cold storage envelope built inside the existing building, the panel work cut and sealed on site, and the building's structural column integrated into the envelope without compromise. WFE delivered the build with one crew from design through commissioning. No subcontracted handoffs between the company that quoted the job and the company doing the work.
Deep Dive
What in-house cannabis cold storage installation looks like
Most commercial cold storage sold in Ontario comes through brokers and general contractors who subcontract the install, so the crew on site is rarely the company that quoted the job. 35 Silton ran the other way: the same WFE team designed the envelope, cut and set every panel, and sealed it, which keeps the accountability chain one phone call deep for a facility that has to stay compliant.
Refrigeration plant detail
KeepRite refrigeration plant sized to the 35 Silton cold storage envelope's load and commissioned in-house, with temperature and humidity control set for cannabis cultivation and post-harvest holding. Refrigeration line routing coordinated with the existing building structure to avoid the column path. Full pull-down test on first run.
Project FAQ
01 Why build cannabis cultivation cold storage inside an existing facility?
On-site builds are the right approach when the operator already has a commercial space and needs a cold storage envelope fitted to the actual dimensions of the room. A prefab unit dropped into an existing warehouse leaves wasted clearance at the walls and ceiling and cannot adapt to existing structural elements. A built-in-place envelope uses every cubic foot of the available space, including fitting around existing structural columns, which matters for a licensed cannabis facility working inside a fixed footprint. Built-in-place at 35 Silton was the right call for the operator's space.
02 How do you build a cold storage envelope around an existing structural column?
The column gets wrapped with protective sleeving where it passes through the cold envelope so the column's structural integrity stays intact and the cold storage envelope still seals around it. The panel layout is planned during design so the panel-to-column interfaces are sealed cleanly. The result is a cold envelope that integrates with the building's existing structure rather than fighting against it.
03 What does 'in-house crew' actually mean at 35 Silton?
WFE-employed crew did every part of the 35 Silton build: design, panel cutting on site, panel setting, sealing, and refrigeration commissioning. No subcontracted install team. No handoff between the company that quoted the job and the company doing the work. The same people on the WFE-branded coveralls and hoodies across the site are WFE employees. That is what in-house actually means.
