Self-supporting sandwich-type panel for roofing with a lateral overlapping wing, in a corrugated exterior finish with 5 corrugations and lateral wing overlap over corrugation.
The new 5G Sandwich-type Panel by PRONTOPANEL is composed of an outer steel sheet with pre-painted finish, profiled with 5 corrugations (one of them empty) and ribbed in the inter-corrugation area, providing it with the highest mechanical strength, especially for large distances between supports. Inside, it contains a polyurethane foam core, giving it excellent thermal and acoustic insulation properties. The bottom is finished with a pre-painted steel sheet that can be supplied in white or wood appearance, allowing the panel itself to serve as the interior finishing surface of the building. At the lateral joint between panels, the empty corrugation (wing) is placed over the filled corrugation of the adjacent panel, and both are fixed in place, leaving the fastening visible. This type of overlap provides greater waterproofing security for the roof and simplifies the installation with fewer auxiliary elements.
These properties allow using the insulated sheet with lateral overlap as an alternative to other types of roofing, providing multiple advantages such as:
- Simplicity and speed in installation (there is no need to create multiple functional layers to build the roof).
- Optimization of the supporting structure, as they are designed for large distances between purlins.
- Excellent insulation within the sheet itself, eliminating the need for intermediate insulation, as they are also available in thick layers of polyurethane foam.
- Lightweight system that allows for significant weight savings in the design of supporting structures, providing additional cost savings.
- Improved waterproofing and moisture resistance, as the panels have double protection with a watertight joint at the seam and an overlapping joint cover that conceals the seam from the outside. Additionally, the non-absorbent nature of both the exterior and interior sheets prevents the appearance of stains on the interior surface of the ceiling.
- Customized solution for all roof finishes such as edges, gutters, ridges, and valleys, etc., which, in traditional roofs, often require on-site finishing that is sometimes poorly executed.
