Products Description
The puf panel cold store room standard configuration uses 0.3mm-0.8mm thick PPGI pre-coated galvanized steel sheets, and also supports customization with various materials such as aluminized zinc sheets and 304 stainless steel sheets. The core insulation layer uses rigid polyurethane (PU/PIR) flame-retardant foam material, with uniform and delicate foaming and a dense structure. The core foaming density can be customized to 40-50kg/m³, with a standard density of 40±2kg/m³. The closed-cell rate of the board is as high as 90% or more, and the thermal conductivity is as low as ≤0.022W/(m·k), with thermal insulation performance far exceeding that of traditional insulation boards.

FAQ
Everything You Need to Know
'lt is awesome to work with Element. amazingy organized,easy to communicate with. responsive with next iterations,and beautiful work.
What are PIR coolroom panels?
A: PIR (Polyisocyanurate) panels are high-performance insulated sandwich panels with a rigid foam core, offering superior thermal efficiency, fire resistance, and structural strength for cold storage applications.
What are the panel facings made of?
A: Options include:
✔ Galvanized steel (standard, cost-effective)
✔ Stainless steel (304/316L) (corrosion-resistant for food/pharma)
✔ PVC laminate (hygienic, easy to clean)
Where can I buy high-quality PU panels?
Reputable suppliers provide test reports, certifications (CE, ISO, GB), and warranties.
And contact us emily@etpanel.com
What is the delivery time and payment method of Polyurethane Foam Insulation Sheets?
Deliver time always 15-20 days, and advance payment TT 30% ,balance payment TT 70% before delivery.
Here are the reasons why our cold storage roof panels are the best choice for your project:
✔ Lower thermal conductivity (0.022-0.025 W/m·K vs. PU's 0.023-0.028)
✔ Higher fire resistance (B1/A-class vs. PU's B2 or EPS's flammable rating)
✔ Better moisture resistance (closed-cell structure prevents water absorption)
