There have two popular types of cold room panels. One is PU panel, another is PIR panel. The differences of these two types are fireproofing grade, cam lock, and installation cost and lifetime. Our PU panel can reach B2 fireproofing grade, with durable zinc-coated cam lock, and 42 kg/m3 high density PU foam, and very easy to install. It can keep cold room lifetime to 20 years at least.
CRYO produce high quality PIR panels and PU panels. 75~200mm PU/PIR panel
Our PU panel foam use polyester that reach B2 fireproof grade. It is difficult to burn and without smoke. While other supplier add fire retardant into PU foam, it will generate smoke when it happen fire.
- Cheap quality, low lifetime. - More noise, more power consumption. - Quality problems keep happening, nightmare!

What is the thickness of the color plate?
Answer: Bao-steel brand color plate: 0.5mm, 0.6mm, 0.8mm. The Bao-steel brand is the best in China.
Other suppliers may use 0.326mm, and 0.426mm, not the Bao-steel brand, which is too weak.
For PU panels, the higher density the better insulation, right?
Answer: No. The best density is 42kg/m3. We can do the 42kg/m3 to ensure the best insulation.
If PU panel adds flame retardant, what will cause?
Answer: Flame retardant is bad material. It will cause dense smoke and poor insulation.
What is the warranty for the PU panels?
Answer: We can guarantee you 3 years warranty and design the PU panels used for 20 years. Compared with suppliers, some give 1 year warranty, some even have no warranty grantee.
