Testing Quality
The first two dynamic test images visually demonstrate the flame-retardant properties of our cold storage panel core material. We simulated a real-world fire using a standard flame source, continuously burning the panel surface. As you can see, the panel didn't burn violently. Instead, it carbonized its surface, forming a dense char layer that effectively blocked the flames from penetrating deeper. This is the most critical step! Once the fire source was removed, the open flames on the panel extinguished themselves within a very short time (approximately 2-3 seconds), with no signs of sustained combustion.
The third dynamic test image is a transparent statement about our "closed-cell rate." Our closed-cell rate of over 98% means that the vast majority of the countless cells within the panel are independent and sealed. These countless tiny "vacuum compartments" together create an impenetrable barrier, completely isolating moisture and water vapor.
As a premier manufacturer and supplier of advanced thermal management solutions, we engineer High-Density PU Cold Room Panels designed for rigorous temperature control. These structural insulated panels deliver unmatched thermal resistance, structural integrity, and long-term operational efficiency for industrial cooling facilities.

We understand that specifying structural insulated panels requires precise technical information. Below are answers to the most common inquiries regarding our high-density PU cold room solutions.
1. How do I determine the correct panel thickness for my specific temperature requirements?
Panel thickness is directly correlated with your target internal temperature and ambient external conditions. Generally, 50-75mm panels are ideal for processing rooms (above 0°C), 100-120mm for standard freezers (-18°C), and 150-200mm for blast freezers or ultra-low temperature storage (down to -45°C). Our engineering team can perform precise thermal load calculations to recommend the optimal thickness for your facility.
2. What is the difference between the Cam-lock and Plug-in connection systems?
The Cam-lock system uses embedded eccentric hooks that are locked together with a hex wrench, providing an exceptionally tight, secure mechanical pull, ideal for smaller or highly customized rooms. The Plug-in (tongue and groove) system relies on a precision friction fit, often preferred for large-scale continuous walls where rapid installation and seamless aesthetics are the primary goals.
3. Can these panels withstand frequent, high-pressure chemical washdowns?
Yes. For environments requiring rigorous sanitation, such as slaughterhouses or pharmaceutical plants, we highly recommend our panels clad in 304 stainless steel. This surface material is virtually impervious to rust, oxidation, and the harsh chemical agents typically used in high-pressure industrial cleaning protocols.
4. How does the B1/B2 fire rating impact the safety of my facility?
A B1 rating indicates the material is highly flame-retardant, while B2 indicates it is moderately combustible but self-extinguishing. Crucially, our PIR/PU cores are engineered to carbonize when exposed to direct flame. This means they form a protective char layer rather than melting into flaming droplets, significantly slowing fire spread and allowing crucial time for emergency response.
5. Are the panels shipped with protective film, and how should they be handled on-site?
Absolutely. Every panel is coated with a heavy-duty, peel-off protective film to prevent scratches and abrasions during transit and installation. We recommend leaving this film in place until the final stages of construction. Panels should be stored flat, elevated off the ground on pallets, and protected from direct weather exposure until they are installed.
