Cold Storage Construction in Wyoming

Frozen ground under a freezer floor lifts it. That is the first fact of cold storage in Wyoming, and the reason a freezer slab is not a warehouse slab with insulation on top. Laramie County lists a 36 inch frost line in its design criteria. Evanston requires footings at least 54 inches below finished grade, and 70 inches where footings are unprotected and subject to frost creep. Now put a building inside that holds a floor at zero degrees or colder for years. Without a plan for the soil, the slab will heave, crack and take the racking with it.

We build cold storage: freezers, coolers, blast rooms, ripening rooms and temperature-controlled distribution buildings. The work includes the structure, the insulated envelope, the slab, the dock, the site and the interface with the refrigeration contractor. We build for owners who store and ship food, pharmaceuticals and other temperature-sensitive product.

A cold building is a thermal system first and a structure second. Every decision, from the roof slope to the dock door seal, either helps hold the temperature or leaks energy. We keep the whole system in view so the refrigeration plant is sized for the building we actually build.

Envelope, Slab and Dock

The core scope is the insulated envelope. We erect insulated metal panel walls and roofs with continuous vapor barriers and sealed joints, install overhead and personnel doors suited to the temperature, and build vestibules and dock rooms. We build freezer slabs (the industrial concrete floor work taken to its extreme) with insulation, a vapor barrier, a protective wearing surface and an under-slab system that keeps the soil from freezing.

The site package matters as much. Truck courts, trailer parking, drainage that carries meltwater away from the building, fire protection and utilities all affect operations. Owners that handle rail freight or transload can combine the building with rail spur improvements. We also address refrigeration machine rooms, equipment pads and ammonia or CO2 safety systems in coordination with the refrigeration contractor.

Codes and the Cold

Wyoming has no single statewide building code. The state adopted the 2024 International Codes on June 28, 2024, and local jurisdictions adopt and enforce their own editions. Design snow, wind and frost values are set locally, so a cold storage building in Evanston is designed to different values from one near Cheyenne. The structure must carry the roof snow load plus the weight of rooftop equipment, and the footings must go below the frost line even though the floor system is heated.

Cold storage buildings also fall under special fire protection and mechanical requirements, including sprinklers designed for cold conditions and refrigeration safety rules. We bring those questions to the building department and the fire marshal early, and we submit complete packages to avoid repeat reviews.

Thermal Continuity From Roof to Floor

The common failure in cold storage is a break in the insulation or vapor barrier. Water vapor moves toward cold surfaces, condenses and freezes, and over time it wrecks panels and floors. We detail barriers at every penetration and joint, and we inspect before panels are covered. For slabs, we coordinate the under-slab heating or ventilation with the geotechnical engineer and the refrigeration designer.

We also build with the refrigeration plant in mind. Panel layouts, pipe penetrations, evaporator mounting and defrost drains are marked on the drawings before ordering. When the refrigeration contractor arrives, the building is ready for them, with no field cutting of finished panels.

Rail, Roads and the Wyoming Supply Chain

Cheyenne Logistics Hub covers about 2,000 acres southwest of Cheyenne with access to both BNSF and Union Pacific, I-80 and I-25, a short-line operator, transloading and rail car storage. About 1,500 acres were unsold and unoccupied as of the December 2022 report. For a cold chain operator, rail and interstate access in the same place changes the economics of a frozen distribution building.

Cold storage in other parts of the state faces longer hauls and smaller markets. We help owners decide whether the building should be a regional hub, a processing-adjacent facility or a small dock-based cooler. Our cold storage industry page covers the buyers and their needs.

Seasons, Panels and Refrigeration Lead Times

A cold storage project has three long clocks. Panels, refrigeration equipment and electrical gear each take months to arrive. We order them as soon as design is approved. The slab and under-slab systems are placed in warm months wherever possible, because curing, vapor barrier installation and insulation all work better above freezing.

Commissioning takes longer than owners expect. Pulling a building down to freezer temperature must be done gradually to protect the slab and panels. Product cannot be loaded until the room holds temperature and the owner approves it. We build that period into the schedule so the lease or customer contract does not start before the building can perform.

What Drives the Cost of Cold

Temperature range is the largest driver. A cooler is simpler than a freezer, and a freezer is simpler than a blast room. Building height, rack type, dock count and the rail or truck layout all follow. Electrical service and refrigeration equipment make up a large share of cost, and utility upgrades can add time as well as money.

Frost protection under the slab and the quality of the vapor barrier are the pieces owners sometimes try to trim. We advise against it, because failures there are expensive and slow to repair. We can show the operating cost of different insulation levels so the choice is based on life of the building. See the related refrigerated dock retrofits page for the smaller version of the same work.

Tell us the temperature and the site

Tell us the temperature range, the pallet count and the site. We will price the envelope, slab and dock, and show how the refrigeration plant connects. If you are weighing a bigger distribution site, our work on Cheyenne and fulfillment centers may help.

Common Questions

Why do freezer floors need heat under them?

Soil under a freezer slowly freezes if the floor is held at or below zero. Frozen soil expands as ice lenses form, and that can lift and crack the slab. Under-slab heating or ventilation keeps the soil above freezing. The system is designed with the soil data, the temperature and the insulation thickness in mind.

Can a standard warehouse be converted to freezer storage?

Sometimes, but it is rarely cheap. The slab, walls, roof and doors all need to be rebuilt or lined for cold. Where the existing slab is sound, an insulated slab can be added on top, but the height and loads change. We survey the building and give owners an honest comparison of conversion and new construction.

How long does a cold storage building take?

Design, permit and equipment lead times often take longer than construction. Once the site is ready, a typical building shell can go up in months, followed by refrigeration installation and commissioning. Weather matters for slab and panel work, and distance to the site matters for deliveries and labor.

What can go wrong with panel walls in extreme cold?

Joints that are not sealed let vapor in, and the vapor condenses and freezes inside the wall. Panel movement from temperature swings can open joints. Careful installation, flexible sealants, correct fasteners and a continuous vapor barrier prevent most failures. We inspect joints before moving to the next stage.

Who is responsible for the refrigeration system?

Usually a separate refrigeration contractor under the owner or under our contract, depending on the project. We can manage both and coordinate the interface. Either way, the building and refrigeration designs should be developed together, not one after the other.
