Wall Sandwich Panels have become increasingly popular in subsequent constructions and cleanroom projects in the contemporary building industry, as they represent an outstanding solution in terms of thermal insulation, fire safety, and speed of installation. The most common core materials are PIR, PU, EPS, and rock wool, but they are used in different applications. A short introduction to their difference and usage is given below.

PIR Sandwich Panel is made of polyisocyanurate as the core material, which has good thermal insulation, and it is also highly inflammable, so it is widely used in cold storage factories, food processing plants, pharmaceutical clean rooms, etc.
PU Sandwich Panel is made of polyurethane core material, which offers decent thermal insulation at a relatively fair cost and is mostly applied in industrial structures, warehouses, and other related buildings.
EPS Sandwich Panel
EPS Sandwich Panels are lightweight and economical as they use polystyrene foam core material, so they are suitable in temporary constructions, mobile buildings, and other low fire resistance necessities, as they provide very good value for money.
Rock Wool Sandwich Panels consist of rock wool fibers, which have the best fire resistance and good sound insulation ability, so they are applicable to cleanrooms, high-temperature workshops, chemical plants, and other places where fire is sensitive.
When selecting Wall Sandwich Panels, consider the project's requirements for insulation, fire resistance, and budget:
Cold storage, cleanrooms: PIR/PU
Economical buildings: EPS Sandwich Panel
High fire resistance requirements: Rock Wool Sandwich Panel
Different core materials determine the performance and applications of Sandwich Panels. Whether prioritising insulation, fire resistance, or cost-effectiveness, there is always a suitable option for your project.
