Coolroom Doors for Commercial Walk-In Coolers and Freezers

A plug frame is designed for older walk-in coolers where the original opening was cut for a plug-style door — it fits into the existing rough opening. A jamb frame is a full perimeter frame that mounts to the face of the wall panels. Choosing the correct frame type ensures a proper seal and minimizes installation time on your specific walk-in box.

In most sub-zero freezer applications, a heated jamb or heated frame is strongly recommended. Without it, ambient moisture freezes at the door jamb, causing frost buildup, door stick, and energy loss. ELT offers heated frame and heated plug frame options on freezer doors rated for service down to -40°F, making them standard spec for high-cycle and pharmaceutical cold-chain freezer doorways.

Most prehung swing doors install in approximately one hour — the door and frame drop in over existing wall panels with no panel replacement required. Sliding doors with track, trolley, and header typically take two to four hours. Both designs are engineered to minimize cold-storage downtime to the shortest possible door-swap window.

Yes. ELT replacement doors are compatible with any walk-in cooler or freezer brand, including Kolpak, Amerikooler, Master-Bilt, Nor-Lake, US Cooler, Bally, Polar King, W.A. Brown & Son, and all major OEM and custom walk-in manufacturers. The prehung design installs over existing wall panels without requiring panel replacement.

Walk-in cooler and freezer swing doors feature an R32 PC20 rigid foam board insulation core, providing high thermal resistance to reduce compressor run-time and cut energy costs. The insulation core meets DOE 2017 energy efficiency compliance standards and is engineered for both standard cooler and sub-zero freezer temperature ranges.

Yes. ELT Custom Coolers offers multiple financing options. Affirm provides four interest-free installments on many products, or 0% APR for six months. For larger orders, MyCloudFunding equipment financing is available. These options help restaurants, facility managers, and cold-storage operators spread the cost of door replacement without impacting cash flow.
