Cold Room Panel

We normally use PU (Polyurethane) or PIR (Polyisocyanurate Foam) as the cold room panel core , both side surfaces use stainless steel, aluminum sheet, galvanized steel, etc. Panel density is  >42kg/m³. And cold room panel has B1/B2/B3 fireproof Grade. B1 is the top grade, B3 is the worst.We use B1 or B2 Grade, depend on clients’ need.

The division of fireproof grade is generally determined by the “oxygen index”. The oxygen index of the core material of B1 grade fireproof panel must be >32 (in the combustion test),  B2 grade must be >26, and those <26 are B3 grade plates.

Simple Test Method: Take a small piece of core material and ignite it. 

#Grade B3: Easy to ignite and has dripping burning substances.       

#Grade B2: Left the fire self-extinguishing.                   

#Grade B1: Difficult to ignite.

PU panel advantages:

#1. Low thermal conductivity
#2. Beautiful shape and easy installation
#3. Good fire resistance
#4. Non-toxic and tasteless
#5. Wide temperature range
#6. Waterproof and moistureproof

PIR panel advantages: 

#1. Lower thermal conductivity

#2. Light weight shockproof

#3. Cryogenic insulation material (Used for a variety of pipes and equipment from -196°C to +120°C)

Tips: PIR panel mostly used in Large or huge industrial plants, cold storages, garages, mobile homes, exhibition halls, gymnasiums,etc.

Panel Connection

2 Ways of Connection

There are two ways of panel connection: slip joint and camlock.Two of both can firmly install the Cold Room.

Slip Joint Advantages

#1. Improve insulation and air-tightness of the joints. 

#2. Excellent thermal insulation, good waterproof.

#3. Beautiful appearance, durable, easy and fast installation.

The slip joint system is a special type designed for assembling large and medium-sized cold room. It is combined with light steel structure or concrete frame to assemble the cold storage. Its appearance, area and volume can be freely designed according to different needs.

Camlock Advantages

#1. Energy saving, good thermal insulation performance, strong pressure resistance, beautiful appearance.
#2. Easy to use, long life, high density, high strength, anti-aging and corrosion resistance.
#3. Easy to assemble and combine to save space for building large and medium-sized cold storage.
#4. The construction period is short, which is convenient for customers to put into production as soon as possible.

Our Panel Installation Procedure

1st Step: Wall Panel Installation

#1. Install the wall panel from the corner.

According to the drawing, drill holes in the correct panel position, and the electric drill should be perpendicular to the panel surface when drilling. Erect the wall panels and place soft materials (such as foam) on the ground to prevent any damage to the panels. Then check whether the wall panels are in the correct position (Checks are required from beginning to end). After the position is fixed, welding  angle iron onto the plate beam, meanwhile fix the inner and outer corners.

#2. After the two wall panels at the corner are installed, start to install the next wall panel along the corner.

Before installation, apply white sealing paste onto panel corners of the (convex) groove. The sealing paste should be dense and uniform.

#3. Hit with a hammer between the panels to make them closer.

Use connectors to wedge the wall panels each other, and which are respectively fixed in the gap between the wall panels. The lower connector should be as low as possible, so that it can be covered after pouring concrete. The gap between the panels should be 3mm.

2nd Step: Top and Floor Panel Installation

#1. Start from the corner of the cold room to install the top and floor panel.

According to the drawing,  fix panels to the correct height and position. The panels should be placed on the wall panel and the T-shaped iron. Then fix the top/floor panel and the T-shaped iron with rivets, connect the corner panel between the top/floor panel and the wall panel, then install the next panel.​​

#2. Fix the panel connectors outside the cold room.

Each panel seam should be fixed with 3 connectors: each one at both ends of the panel and the rest one in the middle of the panel (the length of the top panel is less than 4 meters, can only use 2 panel connectors).​​

#3. Ceiling C-shaped steel installation.

Place the C-shaped steel in the correct position due to the drawing, then open the top panel at the position of the bolt hole, and use the bolt to connect the angle iron with the panel firmly. Finally welding the ceiling C-shaped steel to the purlins.

3rd Step: Corner Panel Installation

#1. Apply sealant to all the contact between corner panel and other panels.

The corners between the wall panels should be fixed in sections to facilitate the pouring of polyurethane foam. The corner panel for fixing the top panel should have a gap every 500mm (the size of the gap is subject to the foam material), and then fix it on the top panel and wall panel.

#2. The corner plate is fixed with rivets.

The rivet space is 100mm, and the rivets fixed on the corner should be in a straight line with equal space.

Yes, can use cold room panels in outdoor applications with proper weatherproofing. Specialized coatings or cladding systems can be applied to protect the panels from exposure to the elements.

Cold room panels have moisture-resistant function. The insulation core and the panel joints are typically sealed to prevent moisture ingress and minimize condensation. Use proper vapor barriers and insulation installation techniques to control moisture-related issues.

Cold room panels primarily focus on thermal insulation rather than sound insulation. However, additional measures, such as installing sound-absorbing materials or soundproofing panels, which can reduce noise transmission.
