PU-R roofing sandwich panel (polyurethane core)

WHEN THE INSULATION LEVEL AND PRICE MATTER

The rigid polyurethane foam core provides excellent thermal insulation for buildings. This comes from the excellent thermal conductivity coefficient, λ = 0.022 (available with PIR-core sandwich panels), unparalleled by any mineral wool or EPS sandwich panel. The overall solution from Balex Metal can be less expensive than mineral wool sandwich panels, by some 40-60%.

The polyurethane-core sandwich panels provide a high fire integrity, achieved by the unique double-sided profile of the panel joint lock faces. 
The Balex Metal sandwich panels are delivered with superior protective coating which prevents corrosion.
