Sandwich wall panels are one of the most critical components of prefabricated houses. They determine not only the thermal insulation and fire safety of the building but also its installation efficiency, durability, and energy performance
What Is a Sandwich Wall Panel?
A sandwich wall panel is a composite building material consisting of:
Two outer metal sheets (usually color steel sheets)
One insulated core material in the middle
These panels are factory-produced and installed directly on-site, making them ideal for prefabricated, modular, and container houses
Rock Wool Sandwich Panels
Material Characteristics
Rock wool is made from natural basalt melted at high temperatures and spun into fibers. It is classified as a non-combustible A1-grade material
Key Advantages
Excellent fire resistance (up to 1000°C)
High sound insulation performance
Good thermal insulation
Strong dimensional stability
Typical Applications
Worker accommodation
Schools & hospitals
Industrial buildings
Emergency housing projects
EPS Foam Sandwich Panels
Material Characteristics
EPS (Expanded Polystyrene) foam is a lightweight insulation material with good thermal performance and cost efficiency
Key Advantages
Lightweight and easy to install
Good thermal insulation
Lower cost compared to rock wool
Suitable for temporary or budget projects
Fire Performance
EPS panels usually meet B1 fire-retardant standards, suitable for non-high-risk areas
Improve Overall Efficiency
Compared with traditional brick walls, sandwich wall panels offer :
Faster installation
Reduced labor cost
Better energy efficiency
Cleaner construction sites
When making a choice, one should take into account all the factors comprehensively :
Project service life
Fire protection grade requirements
Local climatic conditions
Budget cost
Is it intended for long-term residence?
Conclusion
Sandwich wall panels with different core materials offer flexible solutions for prefabricated housing. Whether prioritizing fire safety, insulation, or cost efficiency, choosing the right panel ensures durability, comfort, and safety
