With proper installation and care, OUTDURE's ECO-DECKING will provide years of outdoor living pleasure.
To ensure your ECO-DECKING is installed correctly, carefully read and understand the following information on
• Expansion and contraction
• Butt joint details
Instructions have been prepared to ensure your deck looks great now and in years to come. Failure to follow these instructions may result in unsatisfactory installation and void your warranty.
Information you need to know about expansion and contraction...
Composite products expand in warmer temperatures and contract in cooler temperatures. Expect gaps between butt joins during cooler temperature (night/winter). These butt join gaps will close up during warmer temperature (day/summer). Refer to our ‘Expansion and contraction’ table to find out the expected amount of expansion and contraction you can expect.
To achieve the best looking result, consideration is required when determining the layout of your decking boards to minimise the visual impact of gaps between butt joins.
Installation details are provided for:
1. General control measures
2. Multiple boards – laid end on end
3. Breaker boards – positioned in between butt joins (recommended)
1. General control measures - pinning the boards
To achieve the best looking result we recommend expansion and contraction control measures are used for all deck installations, including decks less than a full board in length. Even the best efforts of an installer may result in some clips being installed tighter than others. If a board has a tighter clip at one end of the board, this may cause the boards expansion and contraction to be more apparent at the other end of the board.
To minimise the visual impact of gaps between butt joins, use two screws per board driven on a 30 degree angle through the side of the board into the joist. These screws are to be positioned on neighbouring joists, either side of the middle of the board length.
2. Multiple boards – laid end on end
Below are suggested details to use when laying boards end on end. To ensure boards expand and contract uniformly in length we suggest using two screws per board driven on a 30 degree angle through the side of the board into the joist. These screws are required on neighbouring joists, either side of the middle of the board length. We recommend using breaker board installation method for best installation results.
3. Breaker boards – positioned in between butt joins
In most it is recommended to use a breaker board to create one or more continuous seams perpendicular to the run of the boards across the deck surface. This technique is used to control the seam and make it appear to be a part of the design rather than random butt joints spread throughout the deck.
Below are suggested details to use when using breaker boards between butt joins. Two screws per board driven on a 30 degree angle through the side of the board into the joist are required. These screws are required on neighbouring joists, either side of the middle of the board. Install the breaker board as suggested in ‘breaker board fixing detail’.
