Real Garden Transformations: Timber vs. Composite
Drag the handle (or use the slider below) to compare a weathered timber deck with the same garden finished in our grey composite boards.
How to Install Composite Decking in Three Steps
A confident DIYer can lay a typical garden deck over a weekend with standard tools.
Select Your Board Range
Choose between our Classic solid-core boards and the Shield capped range with its 360° polymer sleeve. Both fit the same hidden clip system, so you can mix ranges across zones of the same garden.
Prepare Your Substructure
Lay treated timber or aluminium joists at 300mm centre-to-centre spacing on a firm, free-draining base. Correct centres keep every board rigid underfoot and protect your 25-year warranty.
Install with Hidden Clip Systems
Snap stainless steel clips into the board grooves and screw once per joist — no visible fixings. The clips set perfect, seamless 3mm side and 6mm end gaps automatically as you go.
Watch: Fitting a Composite Deck
See the hidden clip system, joist spacing and board cutting in practice before you start.
Why choose Enrico composite decking
360° Enrico Shield™ Capped Protection
Every Shield board is wrapped on all four sides in a co-extruded polymer sleeve, bonded to the core during manufacture. That 360° cap seals the wood-plastic core against water, red wine, oil and barbecue fat, shrugs off UV so the colour you choose is the colour that stays, and keeps every board in a batch perfectly consistent — no staining, sealing or repainting, ever.
Seamless Finish with Hidden Fixing Clips
- Stainless steel clips sit inside the board groove — no screw heads on the surface.
- Clips gauge perfect 3mm side and 6mm end gaps for drainage and expansion.
- Completely smooth, splinter-free surface that's safe for bare feet and paws.
- Around 40% faster to lay than face-screwing each board twice per joist.
Tested for British Weather: Certified Anti-Slip
Our brushed grain surface is wet pendulum slip tested to a certified Pendulum Test Value of PTV ≥36 — the HSE's “low slip risk” threshold — in the rain, not just the lab. Grooved profiles channel water away instead of pooling it, and the capped surface starves algae and moss of the damp timber fibres they feed on, keeping the deck sure-footed through a British winter.
Sustainable Living with Zero Annual Maintenance
Each board diverts roughly 12kg of reclaimed hardwood fibre and recycled plastic from landfill, and not a single fresh tree is felled to make one. Once it's down, the yearly ritual of sanding, staining and re-oiling simply disappears — an occasional brush and soapy rinse is the entire maintenance schedule for the life of the deck.
Technical Specifications
What every board is made of
| Material | Share | Purpose |
|---|---|---|
| Reclaimed hardwood fibre | 55% | FSC-certified offcuts and sawmill by-product — gives boards their density and natural grain |
| Recycled HDPE polymer | 35% | Post-consumer plastic (bottles and packaging) — binds the core and blocks moisture |
| UV stabilisers & additives | 10% | Colour pigments, UV inhibitors, anti-fungal agents and bonding additives |

| Expected lifespan | 25-year warranty | 25-year warranty | 10–15 years with upkeep |
| Rot, warp & splinters | None | None | Prone to all three |
