Standard Decking Specifications:
- Joist Spacing: Standard 400mm (16") joist center spacing is required for domestic wood decking; 300mm is recommended for composite boards.
- Expansion Gap: Leave a 5mm to 6mm expansion gap between parallel deck boards to allow timber expansion and drainage.
- Fasteners: Allow 2 screws or fasteners at every joist intersection per board run (approx. 35 to 40 fasteners per m²).
