- Width-to-Width: The general width-to width gapping is 2-5mm.the gapping in-between decking by clip is determined by the clip size.
- End-to-End: The general end-to-end gap is determined by a number of factors, the length of the composite decking boards being installed, the temperature at installation, the co-efficient of thermal expansion/contraction, the highest temperature expected during the year and whether the boards are exposed to full sun and/or shade. Expansion could be as much as 10mm at either end of the decking board depending upon the factors mentioned above.
- End-to-Width: The general end-to-width gap is determined by a number of factors, the length of the composite decking boards being installed adjacent to a longitudinal composite decking board, the temperature at installation, the co-efficient of thermal expansion/contraction, the highest temperature expected during the year and whether the boards are exposed to full sun and/or shade. Expansion could be as much as 10mm on the decking board depending upon the factors mentioned above.

How to install composite decking – A guide to assist with installation
Step 1 Install bullnose edging board
Step 2 Install facial board if needed
Step 3 Install the composite decking
Put the decking clips we provided on each joist and drill the screws approx 80% in, then push the sec board in and tighten the screws up. Repeat the same process for the rest boards.
Please note: you don’t have to put the screws super tight because it might be pulled out when the board moves
Step 4 leave a gap
Check out the temperature when you are installing the deck and decide how much gap you need to leave:
For a 5.4m full length
leave 3mm on each end when the outside temperature is 30 degrees,
leave 5mm on each end when the outside temperature is 20 degrees,
leave 7mm on each end when the outside temperature is 10 degrees,
