What thickness do I need for my cold storage temperature?

The required thickness depends on your target internal temperature and local climate conditions. Our PIR core has a thermal conductivity 0.022 W/m*K - the lowest among practical insulation materials. Share your temperature requirement and we will provide a calculated U-value recommendation.

Can you manufacture non-standard sizes? We have an unusual opening?

Yes - every panel we produce is made to order. We do not hold fixed-size inventory. You can specify any width, length, and thickness within our production range, and we will manufacture to your exact dimensions.

Product Q&A

Q:What is your terms of delivery?

EXW,FOB,CFR,CIF,DDP.

Q:What is your sample policy?

We can supply the sample if we have ready parts in stock, but the customers have to pay the courier cost.

Q:What is the delivery time?

The delivery time depends on the size and quantity of the construction project. Usually, the goods will be dispatched within 30 days after receiving the payment. For some large orders, the delivery may be delayed.

Q:How do I know the bulk order will match the sample?

This is the most important question any buyer should ask. Our answer: every unit in your bulk order is inspected individually before dispatch - not by sampling, but 100% piece by piece. We check core density, dimensional tolerance , surface finish, and joint engagement against your approved sample specification.

Q:What after-sales support do you provide if there is a problem?

Our technical team is reachable within 24 hours for any post-delivery issue - from installation guidance to product performance questions. If a verified quality issue arises from our manufacturing, we resolve it directly: replacement panels or a credit note, without lengthy back-and-forth.
