Trouble free decking - for life!
If you enjoy maintenance work on your decking and replacing it every few years buy tanalised timber or a plastic/wood composite decking with sawdust or other fillers in it. Both will keep you busy with maintenance and replacement unless you don't care what it looks like.
Both will absorb moisture and be subject to water, mould and frost damage.
In fact the plastic and wood composite decking has to be laid at a slight incline to avoid standing water which may be absorbed by the wood content and when heated by the sun will warp and if you get a warping problem and haven't done that, then your warranty is usually invalidated.
Only 100% recycled plastic decking will save you the time and trouble of maintenance and replacement.
Put it down once and forget it for the rest of your life.
No warping, no cracks, no splinters, and it will not only last forever but look good forever too.
Even green algae mops off effortlessly, and it will NEVER rot or be eaten by insects.
High levels of UV protection mean fading is only about 5% over 10 years.

The gaps allowed between supporting joists depend on the type of decking you decide on. Details of spans allowed for different types of recycled plastic decking are contained in the last page of the decking installation guide.
