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.

High density 42kg/m3 PU panels

Our PU panel use best PU foam brand Wanhua. What' s more, we can guarantee 42kg/m3 high density, while others produce low density PU panel. It will influence the cold room life time.

Zinc-coated cam lock, stronger

Our zinc coated cam lock, it is different than other zinc-coated cam lock, the color is clear and no rust even when you use 10 years. Zinc-coated layer is very thick.

B2 Fireproofing PU panels, no risks.
