WPC decking vs timber on the material line
Updated: October 2026
The same click-tile shape is sold as composite and as acacia. WPC decking vs timber is that material test, not a brand ranking. Choose WPC if the material line says WPC or composite and you will not stain it every year. Choose timber if you want a named species and the area line matches the piece count. If the page names both, leave it. The [WPC decking comparison](/hub/fencing-and-wire/wpc-decking) ranks six listings from 15 October 2026. Products Compared used those listings and TDCA guidance, not a weathering test. A qualifying purchase through our links can earn a commission at no extra cost to you.

When composite, when timber
Read the material line once. The three VOUNOT packs say WPC. That passes this test. It is not a laboratory pass, and the shared 3.9 from 17 is one parent rating. The campsite deck and the spa deck also say WPC panels, then fail because their sizes conflict.
Choose timber when you want a species and the area matches the pieces. IKEA RUNNEN, not in this set, is the clean timber click: acacia, nine tiles, 0.81 square metres stated. There is no rule that every composite outlasts every timber. If the page names both materials, buy neither.
What you still have to do
Skipping the annual stain is not the same as no care. The TDCA says you brush timber and WPC so algae and leaves do not make a flat surface slippery, and you mild-clean at least yearly. Stains and water repellents are the timber extra. A seller line about freedom from upkeep means, at most, that you are not buying a stain cycle.
Algae is the shared slip factor. A wet pendulum value of 36 or more is the HSE low-slip threshold the TDCA cites. None of these listings publishes one, and a textured bullet is not that test. Do not claim a fire class. Tile packs here were about £33 to £43. A board price still needs joists and clips.
How they move and how they are supported
WPC tends to expand along its length. Timber tends to move across its width. That is why a timber joist habit is the wrong copy for composite boards. The TDCA also says relatively heavy WPC is generally not as strong as timber, so joist centres are often closer. Hidden clips still need the expansion gap that board’s guide states. Close the gap and the lengthways movement has nowhere to go. The how to lay WPC decking page keeps 300 mm and 400 mm labelled as examples from named board guides, not as a rule for these tiles.
Tiles in this set click onto a flat base, not joists. Leave a gap at walls. These listings do not state the millimetres. A review says the VOUNOT tiles undo unless the surface is properly flat, and composite does not level rocking flags.
The listing that is not this comparison
The floating deck fails the test before price matters. The attribute says Acacia. The bullets say a metal frame and an imitation-wood panel. A timber species in the material field means it is not this category. You cannot put it in the WPC column and you cannot put it cleanly in the timber column. It is 80 x 80 x 25 cm at about £361.01, with 5.0 from one review. That review says the box held one deck, not four.
The three VOUNOT packs do say WPC. The two other platforms say WPC and then disagree with their own sizes. Which pack states a thickness is on best WPC decking. If you wanted composite, stay with a line that says WPC and does not also name a timber species.
One material on the line
If the line says WPC and you will brush rather than stain, the VOUNOT packs pass this test. If you want a named timber and the area matches the pieces, buy that page, not a mixed listing. If Acacia and a composite panel share one page, leave it before you look at the price.
Common questions
When is WPC the right material, and when is timber?
Choose WPC if you want a wood-plastic surface, you will not stain it every year, and the material line says WPC or composite. Choose timber if you want a named species, you accept oil or stain when the colour matters, and the area line matches the piece count. If the listing names both, buy neither from that page. There is no rule here that every composite outlasts every timber.
Does composite still need cleaning?
Yes. The TDCA says you brush timber and WPC alike so dirt, algae and leaves do not make a flat surface slippery, and you mild-clean at least yearly. Stains and water repellents are the timber extra. A line about freedom from maintenance means no staining routine at most. It does not mean the deck never needs a brush after a damp week.
Why do boards move differently from timber?
WPC tends to expand along its length. Timber tends to move across its width. Joist centres for relatively heavy WPC are often closer than a timber habit, because the TDCA says it is generally not as strong. Leave the expansion gap that board’s own guide states. These tile listings are not a joist chart.
Is a listing that says Acacia still WPC if the bullets mention composite?
No. The floating deck says Acacia in the material line and a metal frame with an imitation-wood panel in the bullets. That is two materials. Leave the page. A timber click tile should name the species and an area that matches the count, as the IKEA acacia example does, and that example is not in this set.
Does a textured surface mean a wet slip rating of 36?
No. A wet pendulum value of 36 or more is the HSE low-slip threshold the TDCA cites. Grooves help water leave. They are not that test. None of these six listings publishes a wet PTV. Do not treat a textured bullet as a pass, on composite or on timber.
Which of these six fails the material test before price matters?
The floating deck, at about £361.01, because the material line says Acacia and the bullets say an imitation-wood panel on a metal frame. The three VOUNOT packs say WPC, so they pass this test and still face the shared review file. The two remaining platforms claim WPC panels and then contradict their own sizes, which is a different failure.
