Applications
Steel Buildings for Cold Storage and Logistics Facilities
A cold storage building is a temperature-controlled warehouse in which a pre-engineered steel frame supports an insulated envelope, usually made of sandwich panels with sealed joints. The steel structure carries the roof, refrigeration equipment and internal panel systems while the envelope controls heat flow and moisture.
Challenges & Our Response
- 01
Air and vapor leaks cause ice build-up and energy loss.
Insulated sandwich panels with sealed joints, continuous vapor control on the warm side and carefully detailed penetrations keep the envelope airtight.
- 02
Refrigeration units and evaporators add heavy roof loads.
Plant weights and hanging points are defined early so rafters, purlins and support frames can be designed for them.
- 03
Steel exposed inside cold zones can attract condensation.
Where possible the frame is kept outside the cold envelope or the panels are hung from the structure, limiting thermal bridges.
- 04
Loading docks are a major source of heat gain.
Insulated dock doors, seals and enclosed dock areas are framed into the building to reduce air exchange during loading.
Typical Configuration
| Frame type | Clear-span or multi-span rigid frames |
|---|---|
| Envelope | Insulated sandwich panels for walls, roof or internal ceilings |
| Panel thickness | Selected for the room temperature and climate |
| Roof system | Insulated panel roof or standing seam roof over an internal cold room |
| Plant support | Roof platforms or internal frames for refrigeration equipment |
| Doors | Insulated sectional and sliding cold-room doors |
Indicative values for early planning only. The project engineer confirms every dimension and load to the governing code.
Recommended Features
- Insulated sandwich panels with sealed, interlocking joints

- Insulated dock doors with seals and canopies
- Internal partitions between temperature zones
- Collateral load allowance for ducts, evaporators and lighting
Keeping the cold in and the moisture out
In a cold store the envelope does far more work than in an ordinary warehouse. Heat flows inward through every joint and fixing, and warm moist air is driven toward the cold side. If it condenses within the wall or roof it freezes, damages the insulation and adds load.
The detailing therefore focuses on continuity: panels with sealed joints, vapor control on the warm side, insulated trims at corners and floors, and sealed penetrations for pipes and cables. The steel frame is arranged to keep thermal bridges to a minimum.
Structural planning for temperature-controlled buildings
Refrigeration equipment, suspended ceilings and duct runs can add considerable load to the roof. These collateral loads, along with any plant platforms, must be given to the project engineer at the start.
Many owners combine chilled, frozen and ambient zones in one building. Internal insulated partitions and separate floor insulation zones are coordinated with the frame grid so that each room can be built and sealed independently.
Frequently Asked Questions
Are sandwich panels required for cold storage?
Insulated sandwich panels are the most common solution because they combine insulation, vapor control and finish in one element. Other insulated systems are possible, but the airtightness and vapor control must be equal.
Can a cold room be built inside an ordinary steel building?
Yes. An internal insulated box can be built inside a standard frame, which keeps the steel structure in ambient conditions. This is common where only part of the building is refrigerated.
What information is needed to quote a cold store?
Room temperatures, building dimensions, refrigeration equipment weights and locations, door sizes and the code to be used. Panel thickness and joint type are then selected for the conditions.
