Can I put screws through the Excel boards?
We do not recommend puncturing the boards with screws as this will affect the structural integrity of the boards and void its warranty.
The exception to this is when fitting the final board in a run of decking where fitting requires a screw being fitted through the side of the board at an angle to fix it in place.
What clips do I need to fit the Excel boards?
The Classic clips are used to fit the Excel boards, we recommend 100 clips for every 10 boards you order.
You will also need starter clips to fit the first line of decking boards; the amount will vary depending on your design but usually 1 pack of 50 starter clips should be enough to cover areas up to 60m2.
What are the recommended joist spacing for the Excel boards?
The maximum allowed joist spacing for the Excel boards is 400mm from centre to centre, however to make sure you have a solid deck we recommend joist spacings of 350mm centre to centre.
What expansion gap should I leave at the end of the Excel boards?
There are a few factors to consider when leaving an expansion gap:
- The ambient temperature
It is safer to leave a 6mm expansion gap between boards when laying them in average temperatures.We do not recommend laying the deck in extremely high (>20°C) or low (<5°C) temperatures as this could result in the boards not having adequate expansions gaps during average temperatures.
- What you are butting the board up against
When butting the boards up against a surface that will not expand, it is fine to leave a 3mm expansion gap (dependent on the ambient temperature as mentioned above).
When butting boards up against each other (end to end) it is important to leave a larger 10mm expansion gap. This allows adequate space for both boards to be able to expand when the temperature rises.
Failure to leave enough of an expansion gap can result in warping or splitting of the decking boards.
Which side up should I lay my Excel decking boards?
The Excel boards can be laid either way up. One side has a textured wood grain effect, whilst the other side is grooved.
What should I use to cut the Excel boards?
We recommend using a sliding electric mitre saw circular saw with a minimum of a 40 tooth alternate top bevel finish blade.
