WPC Decking in Perth: A Complete Guide
What WPC decking actually is, why it suits Perth's climate, and what to expect from installation and upkeep.
What is WPC decking?
WPC (Wood-Plastic Composite) decking is made from the same base material as WPC cladding — recycled wood fibre combined with plastic polymers under heat and pressure. It's formed into deck boards that replicate the look of solid timber decking, but with very different performance outdoors underfoot.
Why it suits Perth's climate
Perth decking takes a beating from intense summer UV and dry heat, which is exactly what causes solid timber decking to grey, crack and splinter over time. WPC decking holds its colour and structure far better under UV exposure, and doesn't dry out and crack the way timber does.
No splinters, no sanding
Because it's not solid wood, WPC decking doesn't splinter the way ageing timber decking can — a genuine safety benefit for bare feet, kids and pets. It also never needs sanding back or re-oiling to stay smooth and safe to walk on.
Maintenance
Solid timber decking generally needs oiling or staining every year or two to stop it drying out and greying. WPC decking just needs a regular sweep and an occasional wash down — no oiling, staining or sanding required.
Matching your cladding and decking
Because WPC cladding and WPC decking are made from the same family of materials, they can be selected in matching or complementary tones — a popular choice for alfresco areas, entertaining spaces and pool surrounds, where a cladding feature wall and the deck itself read as one cohesive finish.
Installation
Like timber decking, WPC decking is installed over a joist frame, with boards fixed using a clip or screw system depending on the profile. The main differences from timber are in the fixing details and spacing, which account for the material's slightly different expansion behaviour in heat.
