Main function of a roof panel
A roof panel protects the building against rain, snow, wind and sun while contributing to thermal insulation. In roof applications, correct water drainage is as important as the panel profile and installation detail.
Why are ribs and slope important?
A ribbed surface increases panel rigidity and supports water drainage. If the roof slope, sealing details and fixing elements are not selected correctly, water leakage risk may occur over time.
Application areas
They are used in production facilities, warehouses, logistics centers, sports halls, agricultural buildings, shopping areas and cold storage structures. They provide a practical solution for projects requiring fast enclosure and insulation.
Selection criteria
Panel thickness, core type, sheet thickness, roof slope, screw/fixing detail, ridge and gutter solutions, snow-wind loads and site installation conditions should be evaluated together.
Key points
- Provides fast roof cladding and insulation.
- Ribbed profile is important for water drainage and rigidity.
- Slope, fixing and sealing details should be solved correctly.
