7. Panel site installation general instruction:

1) Site assembly instructions are available from our engineer team,we have related technical services;

2) Ensure that the support structure (column, beam, pedestal) is properly installed,in order to ensure proper alignment of wall and roof panels;

3) The first insulated panel usually starts from the roof or corner. In separate cases, the project may require different installation solutions. Before fixing the panels, ensure that they are properly supported and the right edges (male joints) are upwards, and the panels and surfaces are properly installed;

4) The recommended EPS panel fixing is the panel with minimum distance to the edge.The metal fragments were removed from the drill hole.To ensure tight and waterproof connections, the recommended fixing elements should be 90 degrees to the surface of the panel;

5) Make sure the surface of insulation panels is clean and dry before applying the sealant on the surface.The sealant should be smeared evenly, and the sealant should not be interrupted;

6) Use good tooth jigsaw or carbide circular saw to cut the panel. It is forbidden to use heating surface cutting tools, such as abrasive discs. After completing the panel cutting, remove any metal fragments from the incision immediately;

7) To prevent air and steam circulation, the panel joints must be tight;

8) If the object (shelf, lamp, etc.) is fixed on expanded polystyrene sandwich panel, the sealant must be treated with sealant;

9) The joints between columns and composited panels must be treated with sealant;

10) In order to prevent rainwater from entering the joint of sandwich panel,the contact between the cover plate and the surface of the panel should be treated with sealant;

11) During installation, rainproof protection at the tail end of the sandwich panel should be ensured;

12) During the installation process, the workers move along the roof sandwich plate to ensure the wooden deck along the installation. During installation and maintenance, only one worker should be in the span of a sandwich panel.

Workers can only move along the surface of the sandwich panel on soft shoes.
