Polyurethane is a kind of chemical foam, after hardening molding material, dense texture, light, with better insulation ability;

 

Rock wool is the silk of cotton, the gap is large, and the thermal insulation ability is not as good as polyurethane.

 

However, the rock wool insulation board is not without advantages, on the contrary, it has a higher cost performance and better fire resistance.

 

The difference in the properties of the two materials makes them have different uses in terms of use scenarios. Polyurethane has been the main material of cold storage board, is the best choice for building high performance cold storage; Rock wool is widely used in the field of purification board, more used in the construction of industrial plants and workshops.

 

In addition, rockwool - polyurethane composite insulation board is also widely used, the main body of the board is filled with rock wool, the edge is sealed by polyurethane, both fire and heat preservation dual characteristics.
