How sandwich panels are assembled + technical drawings

1. We recommend entrusting the processing of project documentation and assembly to an experienced construction company with the necessary technology.

2. Everything to check the entire construction, safety of workers, project documentation, construction plans, verticality, horizontality, preparation of tools and techniques and sandwich panels.

3. It is best to perform the installation when it is not raining, snowing, or blowing, when there is no dense fog and in the evening only with good lighting.

4. Assembly work, taking into account the specifics of a specific project, is carried out at temperatures from -10 °C to +40 °C.

5. For wall panels, at least a foundation bar, sealing tape and sheeting elements are installed at the plinth (see technical drawings).

6. TEX galvanized self-tapping screws with EPDM washers are used to fasten wall and roof panels to steel, wood or concrete. Stainless steel screws are used in a more aggressive environment. When fixing the TEX self-tapping screws, make sure that the rubber EPDM pad only slightly expands.

7. Calots are an important part of high-quality fixing of roof panels.

8. The panels can be moved either by means of a vacuum lifter (recommended), by means of a mechanical gripping device (lifting clamps) and a crane, but also manually by means of clamping belts.

9. The installation direction should be opposite to the prevailing wind direction for both roof and wall panels.

10. In the case of roof panels, there may be a situation when there are more rows and the panels are connected by a longitudinal overlap, which is created by undercutting from 150 to 300 mm, depending on the slope of the roof. (you can request undercutting when ordering)

11. Before fixing, put down the protective transparent film. The foil must be removed within 3 months, because the paint and the top of the sheet will be damaged.

12. We recommend sticking sealing tapes over the entire structure and at the sheeting elements.

13. The horizontal and vertical attachment of the wall panels must be perpendicular to the structure and aligned according to the spirit level. We align the roof panels at 90° also to the structure.

14. In the case of roof panels, it is recommended to use a crane to move the entire package to the roof of the building with subsequent fixing. Of course, this also applies to wall-mounted ones, so that the package is as close as possible to the installation.

15. The panels fit together easily because they use a tongue-and-groove system on both types of panels.

16. The minimum slope for roof panels is 4%, and when they are connected in several rows, 7%.

17. In general, it is easier to cut holes in the panels before installation, but they can also be cut afterwards.

18. Circular saws or straight line saws are used for cutting panels and not carbon grinders (flexes), which will damage the surface of the panel. We recommend placing the panels on stands (goats) before cutting.

19. We recommend an inspection of the facade, roof panels, cladding elements and gutter system once a year. After the inspection, any damage must be removed and all panels washed with a low-pressure device with a non-aggressive cleaning agent and a sponge.

20. According to the plans and procedure, we install important functional, protective and aesthetic cladding elements together with sealing tapes.

21. The sandwich panel system can be mounted on all types of structures such as wood, concrete or steel. A steel frame is most often used.

22. Horizontal laying of panels is recommended for several reasons, namely: better mechanical and load conditions, cheaper construction, lighter construction, no intermediate beams, simple installation, easier transport and handling due to the shorter length of the panels.

23. Structural profiles, such as thin-walled cages, are intended for use primarily as cages for ceilings, roofs and walls of steel halls. Thin-walled profiles are available as standardized Z and C profiles or as special profiles. They enable precise and quick assembly. These profiles are used as prisons and wings for all types of halls.

24. During construction, you will need a cordless screwdriver, a circular saw, a jigsaw, a spirit level, a protractor, pur foam, sealant, a leveling device, sealing tapes, a tape measure, clamping bands, calottes, tinkering tools, screws, a marker, a rubber hammer, goats ( racks), and other tools according to the specific needs of the building.

25. Surveys show that falls from a height are the most common cause of injuries in industry and construction, so pay attention to safety and professional competence when completing the work.

26. Of course, the construction also includes sheeting elements, gutter system, snow barriers, ventilation elements, roof ladders, lightning rods, filter systems, utility networks, skylights, gates, doors, windows, shelters, interior installations, exterior landscaping and more according requirements of the work.
