Technical specifications
5-rib Roof Sandwich Panel with Polyurethane (PUR)
For those looking for efficient, durable, and energy-saving solutions in modern construction, 5-rib sandwich roof panels with a polyurethane (PUR) core are the perfect choice. Manufactured to high quality standards, these panels are widely used in residential, industrial, and commercial buildings. Their technical specifications and advantages deliver maximum value for a wide range of projects.
The panels are constructed with two galvanized steel sheets coated with polymer (thickness: 0.3–0.5 mm, width: 1090 mm or 1200 mm) and a rigid polyurethane insulation layer between them. The polyurethane core provides good fire resistance and falls under the B2 fire classification.
Key Features
