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.
