Multi-layer profiled sheets with Coperall Profile 21 that combine metal sheeting and a bituminous membrane lined with a thick isotropic and rot-proof polyester mat.
Metalbit Tessuto 21 sheets are designed for use in roofing applications where effective condensation control is required in combination with a high noise-abatement and anti-drum performance.

7% nominal gradient subject to local building regulations
