Cold storage facilities: PU panels are the prime choice for cold storage facilities due to their exceptional thermal insulation properties. They help maintain consistent low temperatures and reduce energy consumption for cooling.

Clean rooms: PU panels are well-suited for clean rooms because they offer good thermal insulation and can be produced with smooth surfaces that are easy to clean and maintain.

Building walls and roofs (wider range): PU panels can be used in a wider range of building applications compared to EPS due to their increased structural strength. This includes walls and roofs of industrial, commercial, and agricultural buildings, particularly those requiring good insulation and some load-bearing capacity.

Modular buildings: Similar to EPS, PU panels are also used in constructing modular buildings due to their fast assembly and good insulating properties.

Other considerations:

Fire resistance: PU panels can be formulated with fire-retardant additives to improve their fire resistance properties. This is crucial for buildings with stricter fire safety requirements.

Cost: PU panels are generally more expensive than EPS panels due to the higher cost of PU foam compared to EPS.

Moisture resistance: PU foam has good closed-cell structure that resists moisture penetration. However, for applications with very high humidity or direct water exposure, additional moisture barriers might be needed.

In conclusion, PU sandwich panels offer superior insulation, better structural strength, and wider application possibilities compared to EPS panels. However, they come at a higher cost. The best choice between EPS and PU panels depends on your specific needs, prioritizing cost-effectiveness and basic insulation (EPS) or superior insulation, structural strength, and fire resistance (PU).
