buildings such as stadiums, heat preservation and fire protection are the
primary considerations. The innovative PU & rock wool sandwich panels developed by WEIHUA have promoted the progress of the construction industry.
PU & rock wool sandwich panel adopts
rock wool and PIR composite technology, which is an innovation of new materials
integrating heat preservation and fire protection, and can be used in large
Features of PIR cold storage board:
1. Thermosetting material, flame retardant
2. Low thermal conductivity, good heat
insulation effect and wide application range.
3. It has the characteristics of
fluorine-free, environmental protection, anti-corrosion, and mildew proof.
4. High mechanical strength, dimensional
stability and durability.
5. CNC cutting can meet the requirements of
cold storage with different thicknesses.
Features of rock wool board:
1. High-quality energy-saving building
2. Integrate fire protection, heat
insulation, sound insulation and beautiful decoration
3. High compressive strength
4. Good air tightness and water tightness
PU&Rock wool sandwich panel combines
the advantages of the two. Its technology and production process are milestones
in the building wall and cold storage industry. It has epoch-making
significance and lays the foundation for the further market promotion of the
