The Polyurethane wall panel is generally divided into four types: small seamless corrugated wall panels, slotted corrugated wall panels, concave wall panels and mirror panels. There are two ways for wall panel connections: buried connection and pluggable connection. We don't need any nails or other metal tools. These kinds of connections make the product look more nice, make the wall seem much more smooth.
The rigid polyurethane foam core provides excellent thermal insulation for buildings.This comes from the excellent thermal conductivity coefficient, λ = 0.022, unparalleled by any mineral wool or EPS sandwich panel. The concealed fasteners mean just that: the joints between the panels are hidden from sight, which improves the aesthetic value of the result.
Besides the superb solidity and durability with a beautiful appearance, the hard polyurethane resin foam used for panels performs quite well in heat insulation.
