Cold Room Wall Sandwich Panels with PIR Core
Jawdah cold room wall sandwich panels are PIR-insulated wall panels selected for cold stores and other temperature-controlled spaces, where steady insulation, tight joints and cleanable metal faces keep the room at its set condition.
Jawdah describes its cold room panels as suitable for spaces that need controlled temperature and reliable insulation. They use the same polyisocyanurate (PIR) core as the rest of the Jawdah wall range, and they are chosen for a cold room by thickness, facing material and joint detailing rather than by a separate product line.
This page is for owners, refrigeration contractors and consultants planning cold stores, chilled food areas, pharmaceutical storage or other conditioned rooms in Saudi Arabia. It explains how to read the Jawdah thermal data for a cold room, which design details matter most, and what to put in the RFQ.

Quick answer
Cold room wall panels are insulated sandwich panels used to enclose refrigerated or temperature-controlled rooms. Jawdah supplies PIR-cored wall panels for cold rooms, selected according to the project's thermal and technical requirements. The published wall data gives U-values of 0.48, 0.32 and 0.23 W/m²K for 50, 75 and 100 mm, so a thicker panel is chosen when the room must hold a larger temperature difference.
What makes a wall panel suitable for a cold room
A cold room is a box that must keep heat out continuously. Every square metre of wall, every joint and every penetration lets some heat in, and the refrigeration plant must remove it. A good cold room wall therefore combines a strong insulating core, metal skins that block air and moisture, joints that seal tightly, and internal faces that can be washed.
Sandwich panels meet these needs in one element. The insulated core does the thermal work, the two metal facings act as continuous barriers, and the factory-made edges allow a cold room to be assembled quickly inside an existing building or as a stand-alone structure.
Jawdah facts for cold room panels
Jawdah lists cold storage rooms, food and production facilities and temperature-controlled facilities among the uses of its sandwich panel systems. In its own words, insulated panels can support cold rooms and temperature-controlled spaces when selected according to the project's thermal and technical requirements.
The panels use a PIR foam core, which the company states meets the DIN 4102 B2 fire classification. Jawdah supplies roof, wall and cold room panel systems to projects in Riyadh, Jeddah, Dammam and other regions, and provides a Technical Data Sheet, a System Catalogue, an Installation Manual in hard copy and Tests in hard copy on request.
- Application stated by Jawdah: spaces that need controlled temperature and reliable insulation
- Insulation: PIR foam core
- Wall thicknesses with published thermal data: 50, 75 and 100 mm
- Facing options include stainless steel for hygiene-sensitive rooms
How a PIR panel limits heat gain into a cold room
Heat flows from the warm side to the cold side at a rate set by the temperature difference and by the U-value of the wall. Halving the U-value roughly halves the heat entering through that wall, which reduces the load on the refrigeration plant and the energy it uses.
A closed-cell foam such as PIR resists heat flow because most of its volume is small sealed cells. Jawdah gives a closed cell content above ninety percent for its core, and the metal facings stop air and water vapour from reaching the foam. Together they keep the insulation dry and its performance stable over time.
Typical cold room and controlled-temperature uses
Cold room walls are used wherever a product or process needs a stable temperature that is different from the surrounding building. In Saudi Arabia this includes food distribution, retail back-of-house stores, agricultural produce handling, and storage for temperature-sensitive goods.
- Chilled and frozen food stores
- Food processing and production rooms
- Agricultural produce and date storage
- Pharmaceutical and medical storage rooms
- Supermarket and restaurant walk-in stores
- Controlled-temperature zones inside warehouses
Facings for hygiene and durability
Jawdah facings are available in PPGI (pre-painted galvanized iron), aluminium, stainless steel and galvanized iron, with polyester or PVDF coating; Cloud White is the standard colour. For cold rooms the internal face matters most, because it is washed often and is in contact with stored products or packaging.
As a general rule, white pre-painted steel is the common internal face for general food storage, and stainless steel is preferred where strong cleaning chemicals, high humidity or strict hygiene audits are expected. The external face can be selected separately to suit the surrounding hall or the outdoor exposure.
Choosing cold room wall thickness from Jawdah data
Jawdah does not publish a thickness per cold room temperature. Use the wall thermal table below together with the refrigeration engineer's heat-load calculation: the larger the difference between the room set point and the surrounding air, the lower the wall U-value should be, which usually means a thicker panel.
The same logic applies to the cold room ceiling, which often uses the same wall panels spanning between walls or suspended from the structure; confirm that arrangement with the Jawdah team.
| Wall thickness | U-value (W/m²K) | R-value (m²K/W) |
|---|---|---|
| 50 mm | 0.48 | 1.818 |
| 75 mm | 0.32 | 2.273 |
| 100 mm | 0.23 | 4.45 |
As stated in the Jawdah product data. Cold room temperature ranges per thickness are not published and are confirmed per project.
Core properties relevant to cold rooms
For cold rooms the most relevant core properties are those that indicate stable insulation: closed cell content and dimensional stability. Jawdah lists the following values for its PIR core. They describe the core material and are not a performance rating of the complete cold room.
| Property | Value | Test reference |
|---|---|---|
| Closed cell content | >90% | ASTM D 2856 |
| Dimensional stability | <1 % | ASTM D2126 |
| Core density | 36 up to 38 Kg/m3 | ASTM D 1622 |
| Flammability | Class B2 | DIN 4102-1 |
Values as stated in the Jawdah product data for the PIR insulation core.
Design details that decide cold room performance
Most cold room failures come from details, not from the panel. Thermal bridges at the wall-to-floor junction, unsealed joints, and service penetrations let warm, humid air reach cold surfaces, where it condenses and, in freezer rooms, turns to ice. Plan an insulated floor or a thermal break at the base, continuous sealing at every joint and corner, and sealed sleeves for pipes and cables.
Doors, pressure relief and lighting are part of the envelope too. Coordinate door openings and their frames with the panel layout early, and use Wall Flashings and hygienic corner trims that leave no ledges for dirt. For the general wall range and other profiles, see Wall Sandwich Panels.
Installation considerations
Set out the cold room on a level, prepared base so that panels stand plumb and joints close fully. Engage each panel lock completely and apply the joint sealant specified in the Installation Manual, which Jawdah provides in hard copy. Fix base and corner profiles before the ceiling panels are placed, and keep protective film on the internal faces until other trades have finished.
Pull down the room temperature gradually at commissioning, as is general practice, so that joints and sealants are not stressed by a sudden change.
Checks before handover
Before handover, walk every joint inside and outside, look for gaps at the floor junction and around penetrations, and confirm that all trims are sealed. After the room reaches its set point, inspect the external face of the walls and corners for condensation lines, which indicate a thermal bridge or an air leak that should be corrected.
Common cold room panel mistakes
These errors appear repeatedly on cold store projects and are easy to prevent at the design stage.
- Selecting thickness without a refrigeration heat-load calculation
- Ignoring the floor junction, which becomes the main thermal bridge
- Using unsealed or partly engaged joints
- Choosing an internal finish that cannot tolerate the cleaning regime
- Running pipes through panels without sealed sleeves
- Treating the core's DIN 4102 B2 class as a fire-resistance period
Cleaning and upkeep
Clean internal faces with mild detergents compatible with the coating and rinse with clean water; avoid abrasive tools that scratch the finish and create places for bacteria to collect. Check door seals and joint sealants on a regular schedule, and repair any face damage promptly so that moisture cannot reach the core.

Ask the technical teamFrequently asked questions
Are Jawdah sandwich panels suitable for cold rooms?
Yes. Jawdah states that its insulated panels can support cold rooms and temperature-controlled spaces when selected according to the project's thermal and technical requirements.
What thickness do I need for a freezer room?
Jawdah does not publish a thickness per room temperature. Base the choice on the refrigeration heat-load calculation and the wall U-values: 0.48 at 50 mm, 0.32 at 75 mm and 0.23 W/m²K at 100 mm. Larger temperature differences call for lower U-values.
Which insulation is used in Jawdah cold room panels?
A polyisocyanurate (PIR) foam core. Jawdah lists a closed cell content above ninety percent and dimensional stability below one percent for the core.
Which internal face suits food storage?
Pre-painted galvanized steel in white is common for general food stores, while stainless steel is preferred where aggressive cleaning or strict hygiene audits apply. Jawdah offers both, plus aluminium and galvanized iron.
Can the same panels be used for the cold room ceiling?
Panels are commonly used for cold room ceilings as well, but the ceiling arrangement and span must be confirmed with the Jawdah team for each project.
Why do cold rooms show condensation on the outside?
Usually because of a thermal bridge or air leak, most often at the floor junction, corners or penetrations. Continuous sealing and insulated base details prevent it.
Are cold room panels fire rated?
The PIR core is stated to meet the DIN 4102 B2 fire classification of the core material. That is not a fire-resistance period for the room; confirm any fire requirement with Jawdah in writing.
Which documents does Jawdah provide?
Jawdah lists a Technical Data Sheet, a System Catalogue, an Installation Manual available in hard copy and Tests available in hard copy. Request them from the team for consultant approval.
What information is needed for a cold room quotation?
Room dimensions, set temperature, panel thickness or U-value target, internal and external finish, door positions, floor detail, quantities and delivery location.
