| Structure | Panel thickness | Screw length | Spacing |
|---|---|---|---|
| Wall panels | 174 mm | 240 mm | 400 mm, at every intersection of exterior and interior walls (corner, T-joint) |
| Wall panels | 224 mm | 280 mm | 400 mm, at every intersection of exterior and interior walls (corner, T-joint) |
| Floor panels | 124 mm | 200 mm (220 mm)* | Every second joist or at 1,25 m spacing along the length of the floor panel. *On all load-bearing elements (grillage, beams, load-bearing walls) |
| Floor panels | 174 mm | 240 mm (250 mm, 260 mm, 280 mm) | Every second joist or at 1,25 m spacing along the length of the floor panel, on all load-bearing elements (grillage, beams, load-bearing walls) |
| Floor panels | 224 mm | 300 mm (320 mm) | Every second joist or at 1,25 m spacing along the length of the floor panel, on all load-bearing elements (grillage, beams, load-bearing walls) |
| Roof panels | 124 mm | 200 mm (220 mm)* | One screw into each rafter. One screw into each load-bearing element (load-bearing wall, purlin, ridge beam, etc.). |
| Roof panels | 174 mm | 240 mm (260 mm) | Into every rafter and every load-bearing element (load-bearing wall, purlin, ridge beam, etc.) |
| Roof panels | 224 mm | 300 mm (320 mm) | Into every rafter and every load-bearing element (load-bearing wall, purlin, ridge beam, etc.) |
