Self-supporting Sandwich Panel for Roofing with a lateral overlap wing, featuring an exterior finish with 5 grooves and a lateral wing overlap over the groove; and an interior finish with perforated sheeting with an R3T5 pattern.
The new 5G Acoustic Sandwich Panel by PRONTOPANEL is composed of an exterior steel sheet with pre-coated finish, profiled with 5 grooves (one empty) and ribbed in the inter-groove area, providing it with high mechanical strength, particularly suitable for large spans between supports. Inside, it contains a fire-resistant core of rock wool, providing excellent thermal and acoustic insulation to the panel. The bottom is finished with a perforated pre-coated steel sheet, providing excellent sound absorption of interior noise and serving as the interior finishing surface. 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 the insulated panel with a lateral overlap to be used as an alternative to other types of ceilings with acoustic properties, offering multiple advantages such as:
- Simplicity and speed in installation (there is no need to create multiple functional layers to build the roof).
- Ability to attenuate noise with a single element.
- Optimization of the supporting structure, as they are designed for large distances between purlins.
- Lightweight system that allows for significant weight savings in the design of supporting structures, providing additional cost savings.
- Improved tightness and resistance to moisture, as the panels have double protection with a tight joint at the union and an overlapping finish that conceals this joint from the exterior. Furthermore, since the exterior and interior sheets are not moisture-absorbent, the appearance of stains on the interior surface of the ceiling is eliminated.
- 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.
