PU Edged Rockwool Sandwich Panels are a type of construction material widely used for wall and roof applications in buildings. They are composed of a core material made of Rockwool, also known as mineral wool, which is sandwiched between two outer layers. The edges of the panels are reinforced with polyurethane (PU) material for added insulation and structural support. PU Edged Rockwool Sandwich Panels focus on insulation, fire resistance, and sound absorption, while PU Decoration Sandwich Panels prioritize aesthetics while providing some level of thermal insulation. The choice between the two depends on the specific requirements of the project, including insulation needs, fire safety regulations, and desired visual appearance.
