The installation of the HD Deck XS and the HD Deck Dual is important for the warranty*.
300mm joist centres
Joists should be sent to centres no greater than 300mm to allow the deck to perform to maximum strength.
Do NOT fix with screws
Always use the clips or fitting system provided to secure the deck to the joists. The clips allow the deck to expand and contract down the length of the board.
Allow a 5mm gap at the end of each board to give the deck room to expand. A 3.6m length of deck will expand/contracts by 5mm with a 3º temperature change.
A 20mm gap needs to be left at the board ends when fitting near a solid structure.
Allow for a 1 in 100 (1.0%) gradient to allow water to drain off the deck, away from adjoining buildings.
All clips, screws, end caps and fascias can be purchased with the corresponding deck boards and our secret clip systems means the HD Deck XS and Dual can be installed with a clean finish without any visible, unsightly screws. *For full, easy-to-use installation guides, please contact us.
