Your Reliable Partner and Manufacturer of PIR Sandwich Panel
PIR sandwich panel is also called Polyisocyanurate panel. Compared to the PU panel, it features better thermal insulation, higher strength, and higher fire resistance. PIR panel is an upgrade of the PU panel. It is widely used to make cold room walls and ceilings. The same is good for making building which need to keep warm and offer better heatproofing.

Zonsteel can offer custom-made PIR panels that are suitable for your cold room needs. So, the surface could be 0.5mm or 1mm stainless steel 304 material. The color steel sheet could be PVDF or PVC coating. Another option
for the color is white or any other RAL color. The surface could be smooth or grooved. The small groove shape makes the PIR sandwich panel to higher strength.
The Zonsteel PIR sandwich panel production line has a high output capacity of 3500m2 or double with two shifts. This high output ensures Zonsteel’s delivery time is 12 days.
It is easy to install the PIR panel, as it comes with a tongue and groove joint. The connection of the two panels does not need bolts, but PU foam and sealant. When cold room is designed with subzero temperature specifications, the PIR sandwich panel must go down into the ground to prevent air release and limit heat transfer.
Zonsteel PIR sandwich panel surface is protected with PE film. This prevents scratches and dents. The panels are packed well on pallets and then wrapped with foam and bubble film.
Our installation manual or installation team is available to support your cold room installation.

What Is PIR in a Sandwich Panel?
Polyisocyanurate, or PIR, is a fireproof thermal insulation material derived from polyurethane. It’s an excellent heat insulation foam.
What Are the Properties of Zonsteel PIR Foam?
- Density: 40-42 kg/m3
- Compression strength (thickness direction): 162Kpa
- Bonding strength: 141Kpa
- Size stability: ≤1.5%
- Cell closure rate: 290%
- Water absorption rate: ≤3%
- K-value: 0.020W/(m·K)
From the K-value of PIR foam, it’s the best insulation material. It is widely used as insulation for walls and roofs in different types of buildings and cold rooms.
What Is a PIR Sandwich Panel?
A PIR sandwich panel is clad with metal sheets on both sides, with the core material being PIR foam, used for rigid thermal insulation. Also called Sandwich panel PIR or PIR panel sandwich. It is produced from a one-shot foaming continuous line. Due to its excellent thermal performance, it is widely used for cold rooms, cooling rooms, walk-in cold rooms, and modular walls and roofs. It is also used for flooring.
The thermal conductivity of Zonsteel PIR sandwich panels has a typical value of 0.020 W/(m·K).

What’s the Basic PIR Sandwich Panel Specification?
- Thickness: 50mm, 75mm, 100m,120mm,150mm,175mm,200,250mm
- Core material: PIR (Polyisocyanurate) foam
- PIR density: 40-42kg/m3
- Skin material: Prepainted steel 0.4-0.8mm, Aluminum 0.5-3mm, Stainless steel 0.4-0.8mm
- Length: less than 11.93m
- Width: 1200mm, 1000mm
Figure 2 PIR Sandwich Panel Specification
Zonsteel PIR Sandwich Panel Joint
For walls and ceilings made with PIR sandwich panels that are 50mm thick, you have the option to use either a sealant or spray foam at the joints to achieve optimal insulation efficiency.
Figure 3 50mm PIR Sandwich Panel Joint
When it comes to PIR sandwich panel walls and ceilings with a thickness exceeding 50mm, ranging from 75mm to 250mm, the joints benefit from the combined application of both sealant and spray foam. This dual application is essential to enhance the airtightness of cold storage rooms, coolers, and freezers.
Figure 4 Greater than 50mm PIR Sandwich Panel Joint
What’s the PIR Sandwich Panel Price?
PIR sandwich panel price depends on panel thickness and surface skin thickness. Other factors affecting the price are surface skin type and surface skin paint type.
The PIR sandwich panel price with PE paint < PVDF paint < PVC coating < aluminum sheet < stainless steel. The color will not affect the PIR sandwich panel price, but it will affect delivery time. Normal white color takes 12 days, while other customized colors will take more than 15 days.
PIR Sandwich Panel Fire Rating
The fire rating for PIR sandwich panels is B1, which indicates they are hardly flammable. In Germany, the DIN 4102-1 standard classifies building materials as B1 if they are flame retardant. Although these materials are combustible, they burn more slowly and are self-extinguishing, meaning they do not continue to burn on their own.
Comparison to Other insulated sandwich panels:
- Rockwool panels: A
- PU panel: B2
- EPS panel: B1
- Aluminum honeycomb sandwich panel: B
Figure 5 PIR Sandwich Panel Fire-rating B1
What’s the PIR Sandwich Panel Operating Temperature Range?
It can be used continuously for a long time at -196℃~+160℃, and the size change rate is ≤1.5%

How to Pack PIR Sandwich Panels?
Zonsteel PIR sandwich panels are wrapped in film and placed on pallets, with the bottom padded with XPS board for protection. For long panels, such as those measuring 11900mm, we recommend a width of 1000mm. Two pallets can be placed side by side without rubbing against each other.
Figure 10 PIR Sandwich Panel Packed on Pallet
How to Install PIR Sandwich Panel Walls of Cold Room?
Zonsteel PIR sandwich panels feature a tongue-and-groove joint type. U or L-shaped profiles are placed on the ground to hold the panels, which are then screwed into place. Sealant and spray foam are used to seal the joints, and rivets are used to secure the top and bottom. The exact installation method depends on the cold room’s temperature, type, and height. Walls that are too high may require additional reinforced braces for support.

High-speed Freezer Doors
Zonsteel provides high-speed freezer doors and high-speed cold storage doors which aid in controlling the environment, traffic, and costs in refrigeration rooms. These high-speed doors are created with a thermal barrier.
Figure 23 High-speed Freezer Doors
PIR Sandwich Panel Built Controlled Atmosphere Storage
CA storage rooms are used to keep fruits and vegetables fresh. Horticultural produce generally needs low temperatures and high relative humidity to maximize storage life and maintain quality and flavor. Low temperatures reduce the respiration rate and slow down the metabolic processes that reduce produce quality, but chilling injury will occur if temperatures are too low.
Figure 24 Controlled Atmosphere Storage Door
Use of PIR Sandwich Panels as Interior and Exterior Cold Room Walls/Roofs
When used as interior walls or partitions, PIR sandwich panels have the same tongue-and-groove joint type as ceiling panels. For exterior walls, the joint type differs, and installation can be vertical or horizontal. PIR sandwich panel roofs are corrugated with an overlap joint, facilitating rainwater drainage.
Which Tools Required for Installing PIR Sandwich Panels?
The main tools needed for installation include:
- Pliers
- Electric hammer
- Electric hand drill
- Forklift
- Portable cutting machine
- Hydraulic elevator
- Riveting gun
- Glue gun
What Is the Difference Between PIR and PUR Sandwich Panels?
PUR and PIR are two distinct categories of foam technologies. Polyols can be categorized into two types: polyester-based polyols and polyether-based polyols. The formation of PUR involves a chemical reaction between polyether polyols and isocyanates, whereas PIR is created through a reaction between polyester polyols and isocyanates. Typically, the isocyanate index for PUR panels ranges from 110 to 120, while for PIR, it significantly increases to a range of 200 to 300.

Use of PIR Sandwich Panels as Walk-In Cooler Panels
Walk-in coolers typically store vegetables and fruits at 0 to 5℃. PIR sandwich panels, being excellent thermal materials, are perfect for use as walk-in cooler walls and roofs, with recommended thicknesses of 75mm, 100mm, and 120mm.
PIR core sandwich panel is from an automated continuous PIR sandwich panel production line, with a standard width of 1200mm. It means we can cut height to size, but width not. One panel on each wall end may need to be cut. All necessary profiles and accessories, including cold room doors and flooring materials, are provided and shipped together.
Cam-lock PUR sandwich panels use for walk-in cooler offer the advantage of being pre-cut to size for easy assembly. They can also create sanitary corners with elbow corners.
While PUR sandwich panels have a B2 fire rating, PIR panels have a B1 rating, which is preferable for those who value this aspect.
Figure 25 PIR Sandwich Panel Walk-In Cooler Panels
Use of PIR Sandwich Panels as Walk-In Freezer Panels
Walk-in freezers typically store food at -23 to -18℃. PIR sandwich panels are ideal for use as walk-in freezer panels, with recommended thicknesses of 150mm, 180mm, and 200mm.
