How are sandwich panels installed on a wall or a roof?
Sandwich panels are easy and quick to instal. From practical experience, installing 600 m2 of sandwich panels takes approximately 8 hours for a proficient construction crew.
The steps to instal wall and roof sandwich panels are as follows:
- The construction materials are delivered to the site: the delivery includes sandwich panels, the subframe components (cold-formed shapes), and accessories (including flashing, fasteners, gaskets, seals, etc.).
- The materials delivered by the carrier are unloaded with construction handling equipment.
- The subframes are assembled, and installed with beams, posts and purlins.
- The protective film is removed from the sandwich panels.
- The sandwich panels are fastened to the subframe structural members using suitable fasteners.
- The joints between the sandwich panels are sealed and the flashing is installed.
How many screws do I need to fasten a sandwich panel? This is the most common question from customers at the project preparation stage. A rough estimate is 1.1 fasteners per square metre of sandwich panels. The actual number, spacing and layout depend on the decision of the project design engineer and/or the construction material supplier.
Any type of sandwich panel will do as cladding for walls and roofs. Depending on the project needs, the cladding may include:
- EPS-core sandwich panels (the budget option).
- Mineral wool core sandwich panels (for structures with improved resistance to fire).
- PIR-core sandwich panels (whenever good thermal insulation parameters are essential).
Sandwich panels can be utilised in all structure types. However, while sandwich panels are generally used in industrial applications, some housing projects also use stud partitions and sandwich panels.
Given the short installation time and large unit coverage, sandwich panels are most popular in constructing:
- Warehouse buildings
- Logistic hubs
- Sports facilities
- Cold stores and freezers
- Shopping malls
- Manufacturing buildings
- Office buildings
Sandwich panels can be combined with other structural solutions. A popular option is to instal the panels as external cladding for the outer walls of shopping malls, including sandwich-layered roofing structures: box profile sheets, thermal insulation (e.g. Thermano PIR-core sandwich panels), and a waterproof membrane.
