The main reasons why polyurethane sandwich cold storage panels usually choose B1 fireproof grade are as follows:

 

1. Fireproof performance: B1 fireproof polyurethane cold storage panels have certain performance standards in fire safety and can prevent the rapid spread of fire to a certain extent. This type of board usually has good thermal insulation performance and can meet the temperature control requirements of cold storage.

 

‌2. Applicable scenarios: B1 fireproof polyurethane cold storage panels are suitable for all kinds of places that require refrigerated storage, such as food cold storage, medical cold storage, etc. In the field of cold chain logistics, its wide application ensures the safety of stored items and the stable operation of the entire logistics system.

 

3. Cost-effectiveness: Although B1 fireproof polyurethane cold storage panels have better fireproof performance, their cost is relatively high. B2 fireproof polyurethane cold storage panels have relatively low costs while ensuring certain fireproof performance, which is more suitable for the budget requirements of most cold storage construction projects.

 

4. Market standards: In the market sales of cold storage panels, enterprises need to obtain fire protection and flame retardant grade certification, and B1 is the minimum requirement. Therefore, B1-grade fireproof polyurethane cold storage panels are more common in the market.
