50/75/100/150mm Insulation Thermal Insulation PU Polyurethane Sandwich Panel for Wall and Roof Clean Cold Storage Room

Thermal Insulation

Core materials (such as rock wool, polystyrene, etc.) have low thermal conductivity, which can effectively block heat transfer and meet the temperature control needs of different climatic regions.

Fire Resistance

Some core materials (such as rock wool, glass wool) are non-combustible. Combined with the fire-resistant coating of color steel plates, they can delay the spread of fire and improve the fire safety level of buildings.

Structural Strength and Durability

The outer color steel plates have high strength, and the sandwich structure has good toughness, which can bear a certain load and impact, is not easy to deform, and has a service life of more than 10-20 years.

Construction Convenience

Lightweight (about 10-30kg/m²), with low requirements on the load-bearing capacity of building foundations; factory-produced standardized products, on-site splicing and installation, significantly shortening the construction period.

Aesthetics and Maintainability

The surface has various color coatings, with a neat appearance that does not require additional decoration; the coating is acid and alkali resistant, corrosion resistant, and UV resistant, and daily maintenance only requires regular cleaning with low cost.

Sound Absorption and Noise Reduction

Porous core materials such as glass wool can absorb sound waves, reduce noise transmission, and improve the internal acoustic environment of buildings (such as schools, hospitals, etc.).

Wide Applicability

Core materials and thickness can be flexibly selected according to needs, meeting the functional requirements of various building scenarios such as industrial workshops, residences, cold storage, and prefabricated houses.
