Walk-In Freezers Built to Spec

Building custom walk-in freezers to spec is what we’re known for.

Walk-in freezers require additional considerations and with the experience we bring to the table, we are here to help you make sure you get what you need. With each unit custom-built to your specifications, our walk-in freezers set the industry standard. With access to our design and engineering services, your project will be built to your specifications.

Design considerations include the temperature of the box or the needed R-Value which drives the panel thickness. Floor panels or insulated floors are required for all walk-in freezers. Heated vents are necessary for pressure equalization. Heated doors and or sweeps/thresholds are needed. Application considerations like the size of the walk-in freezer may require complicated underfloor venting/heating below the slab to prevent frost heaving.

Even some walk-in coolers (like Meat or Beer Coolers) should be treated as walk-in freezers due to maintaining temperatures below 32 degrees.

KPS Global does not suggest a wood frame or less than 5” panel thickness for walk-in freezers. While 4” INSULFRAME (HDR) panels are acceptable per the DOE guidelines as ‘minimum’ R-Value required, but that is not always optimal. Based on the Delta-T and humidity conditions, 4” panels pose a greater risk for condensation issues.

With so many things to consider, call KPS Global to help you with your project. Our in-house sales team will work with our design and engineering teams to build your project to spec.

Panels Details

KPS Global® panels are modular for ease of assembly with interlocking tongue-and-groove perimeter panels. KPSG uses a poured-in-place, CFC-free urethane for superior insulation.

Panels can be designed for indoor or outdoor applications. Panel operating temperatures are -40F to 175F. In addition, panels can span up to 22’ without any additional support in most indoor applications.

Tight-sealing, factory-installed double bulb-type NSF approved compression gaskets


Panel frames are constructed of Wood, INSULFRAME® High-Density Rail (HDR) urethane frames or FUSIONFRAME®, a patented frame system that offers the structural benefits of wood and the high-performing insulative properties of foam.

Panels are available in 3½”, 4” or 5” thickness.

Wood frames provide structural support while HDR frames provide a higher thermal value. FUSIONFRAME® panels offer the best of both worlds without having to compromise structural strength for thermal performance.

Cam-Lock System

Panels are fastened with the cam-lock system to ensure a tight seal. Metal clad surfaces, designed to your specifications and with tongue and groove frames, are joined with a cam-lock that allows for easy and fast on-site modular assembly.


Floor panels are constructed in the same manner as the walls and ceilings except for the addition of a substrate under the interior ­finish. Floor options based on intended use and load requirements:

Foot Traffic: Galvanized or Stainless Steel skins over foam

Hand Truck: 1/2” Plywood under any metal UNIFORM LOAD = 1000 PSF

Pallet Jack: 1/2″ Plywood under any metal with ­field applied 3/16″ DTA UNIFORM LOAD = 2500 PSF

Super Floor: 3/4″ Plywood under any metal with stiffeners at 12″ O.C. and field applied 3/16” DTA UNIFORM LOAD = 5000 PSF

Insulation Comparison

Panels are made of solid core, factory poured-in-place
urethane insulation (with a density of 2.2 pounds per cubic foot) to ensure superior performance and low operating costs. The urethane also meets the ignition properties requirements of ASTM D-1929 and is CFC free.

Foam is an important part of the panel. There are two foam options most often used in the industry (polyurethane and extruded polystyrene). Polyurethane foam results in a lightweight, low cost amalgamated panel. The structure bonds and cures as one.  XPS is an inferior option and why KPS Global® does not use this material in its panels. To learn more about these two foam types, check out this comparison and reach out to the experts at KPS Global to discuss the best product for your commercial application.


Interior and exterior panel finish options include:

Texture: Embossed or Smooth

Standard Color – Natural
Optional Colors – White, Tan, Black or Custom

Finishes: Aluminum-Zinc Alloy, Aluminum, Galvanized, Stainless Steel or Antimicrobial

Weights: 20 to 26 Gauge
