Composite garden decking…. Solid, or hollow??
Any experience or concerns from either??
Hollow is about £19 per 4m length; solid is £28 – not an insignificant difference.
I’m looking to deck 2 areas in my back garden, and the cost difference in the two types of decking is going to be close to a grand….
However, if people say ‘hollow decking is rubbish’, then i’d rather spend another grand than waste any money…..

If thats the case DrP then dont wear your stilletto’s on there then, the clip clopping will drive your neighbours mad.
i see no reason to spend an extra grand just for solid, the hollow stuff is pretty strong so with the joist set up you mention it wont be a problem.Posted 1 month agoTroutWrestlerMember
Hollow stuff is used on a walkway in some wetlands near me. I’ve no idea what the centres are, but it does flex noticeably. It also bows in where it is screwed down. You will also need to think about the ends as you’ll be able to see into the plank.
I have no idea who built the stuff I walk on, so I cannot comment whether it is materials or workmanship where the shortfall is.Posted 1 month agopslingSubscriber
It’s not as simple as hollow vs solid – there are good and bad in both! I would say the higher quality hollow extrusions with thick outer and multi-chambered are best. You might expect to pay £30-£40 per 3.6-4.00m length ( x 145mm wide) for the best quality!
Most manufacturers advise 300mm c/s for joists because composite or ‘plastic’ extrusions expand along their length in warmer temperatures – as much as 1.5-2.5mm per metre (wood tends to swell across its width with wet). If any warranty is offered with the product this is probably a requirement, It is also why clips are required for fixing for composites (to allow the boards to move longitudinally) rather than screws / nails through the boards. Again, probably a requirement of any warranty.Posted 1 month agojim25Member
Composite decking has its positives and negatives, one of them being the amount it will expand in the heat especially if you choose a dark colour, as most people do at the moment.
I would advise using Balau hardwood deck boards, very good for the purpose, used on ships for the decks and has a natural anyone slip property to it.Posted 1 month ago
anyoneslip…. not really a selling point 😉
We’re looking at light grey/lighter colours of decking. We’re south facing in one of the sunniest parts of the country, and one area to deck is a bit of a sun trap.
I was using my IR thermometer on some sample pieces laid out in the recent sun – the darker colours got to 58 degrees.
Even if they suited better aesthetically, my kids would melt their feet to the boards….!
I like the idea of composite – i’ve had normal decking in a prev house, and it went green and sliey, adn i hate treating deck boards!
