Cold Storage Facility Construction in New Mexico
Freezer floors crack when the ground under them freezes and swells, which is why a cold storage building starts below the slab, not at the roof. New Mexico has plenty of reasons to build cold space: Leprino Foods runs one of the largest mozzarella plants in the world in Roswell, and Portales alone is home to about 40 dairies and a major dairy solids plant. Cheese, milk powder and produce all need refrigerated or frozen storage close to the plant, and every day a pallet waits outside costs money.
We build cold storage as insulated metal panel buildings on a rigid frame. The panel is the wall and often the ceiling, with a vapor-tight seal that keeps moisture out of the foam. The refrigeration, the floor heat and the doors are separate systems that we coordinate with the refrigeration contractor. The shell is a controlled build, and mistakes show up as frost, ice and a bill for energy. For a facility that sits next to a plant, it can also be built as part of a larger distribution center, with the cold block on one end and ambient dock space on the other.
Cold buildings in the high desert have one advantage: dry air. Condensation is less of a problem than in humid places, but daily swings and strong sun on a metal skin still matter.
Under the slab
A freezer slab sits on an insulation layer over a heat source, either a glycol loop or an electric system, which holds the soil above freezing. Without it the ground freezes, expands and lifts the floor. Soil type matters, and a geotechnical report should be on the table before the slab is designed. Coolers at 35 degrees are less demanding than freezers at minus 10, but both need a plan for vapor control.
The foundation also carries rack loads, which are heavy in frozen storage. Racks, forklifts and traction add up, and the slab sections around dock doors take the worst punishment. We keep joints tight and the pour sequence short to avoid cold joints.
Code, energy and refrigerants
The 2021 New Mexico Commercial Building Code (14.7.2 NMAC) adopts the 2021 International Building Code as amended and took effect July 14, 2023. The 2021 New Mexico Commercial Energy Conservation Code (14.7.9 NMAC) took effect January 30, 2024 and has specific insulation and air leakage provisions that cold buildings meet by design.
Refrigeration brings mechanical code, refrigerant limits and emergency ventilation. Ammonia systems need special rooms and detection, while newer low-charge systems have lighter requirements. The permit for the building and the permit for the refrigeration plant go through different reviews, and we line them up so neither stalls the other.
Panels, seals and doors
Our insulated metal panels are installed with sealed joints and continuous vapor barrier at every penetration. The detail at the base, where the wall meets the slab, is the one most likely to leak, so we mock it up first. Doors are insulated, heated at the frame in freezers and fitted with air curtains or strip curtains where traffic is heavy.
We erect the frame and the panels in the same push to close the building fast, then hand the interior to the refrigeration contractor. For wide cooler rooms, clear-span buildings keep columns out of the racking aisles.
Dairy and food plants
Southwest Cheese announced a $140 million expansion in Clovis that was expected to raise operational capacity by 30 percent. A bigger plant ships more cheese, and cheese needs storage between the vat and the truck. The same logic applies in Roswell, Portales and Lovington. The growth in dairy processing is why most of our cold storage inquiries come from people connected to agriculture and agribusiness.
Cold space also serves distributors, grocery suppliers and produce shippers. A small operator might want a pre-cooled dock addition to an existing warehouse, while a processor wants a full freezer block next to the plant. See how we frame the production side under food and beverage processing.
What cold space costs
Insulation thickness, floor heat, refrigeration capacity and door count drive the number. The panel and the refrigeration plant are usually the two largest lines. A freezer costs far more than a cooler per square foot, and a wider temperature range inside the same building raises the price again.
Operating cost matters as much as first cost. A thicker panel and a tighter seal save energy for decades, and in a state with strong summer sun on a roof, cool-colored panels cut load. We price two or three panel thicknesses so you can compare payback.
Schedule and where it slips
The shell is the quick part. A cold storage building is dried in on a schedule that looks like any other metal building, and then the long items begin: compressors, evaporators, controls, electrical gear and the commissioning period when temperatures are brought down in steps. Floor insulation and heat loops must be in before the slab pours, and the slab must cure before racks go in. We keep a list of long-lead items and order them as soon as the design is fixed.
Where the building is also matters. Portales and Clovis are on the eastern plains where wind and summer storms come across flat ground, and crane days are lost to gusts. In Roswell, where the cheese plant sets the pace for local refrigeration demand, we confirm crane and crew availability before we quote a date, and we tell you when a date depends on the weather. A cold building is also a place where a delayed door or a missing seal delays everything after it. Dry-in dates are real, but commissioning dates should be treated as ranges until the refrigeration contractor confirms.

Send us the setpoints, the pallet count and the site. We will price the shell and floor system, and show the refrigeration scope as a separate line coordinated with your contractor.
Common Questions
Do I need under-slab heat for a freezer?
Almost always, for a freezer running below freezing. The heat keeps the soil under the slab from freezing and lifting the floor. Coolers above freezing usually do not need it, though insulation still helps. A soils report settles the question.
How thick should the insulated panel be?
Freezers use thicker panels than coolers. Typical choices run from about four inches for a cooler to six or more for a freezer, depending on the energy code and the target setpoint. We price two thicknesses and let you compare energy savings against first cost.
Can I add cold space to an existing building?
Yes. A cooler or freezer room can be built inside an existing shell or as an attached addition. The attached option is often easier because it avoids new roof loads on the old building.
How long does a cold storage build take?
The shell goes up at about the pace of any metal building, but the refrigeration plant, controls and commissioning add weeks. Equipment lead times can be longer than the steel. We order early and sequence work around the long items.
