WPC vs Timber Decking: The 2026 Material Comparison Guide
Choosing outdoor decking used to be simple: wood or more wood. Today, the options have multiplied. Each material comes with trade-offs — in cost, maintenance, and how long it actually lasts.
To help you decide, we've compared four of the most common outdoor decking materials across seven dimensions that matter for real-world use: lifespan, maintenance, water resistance, pest resistance, UV stability, cost, and thermal stability.

Breaking down the numbers
Lifespan: The 25‑year difference
Timber decking needs replacement within 5 to 15 years. Pine, the most common budget option, averages just 5–8 years before it starts showing significant wear.
Necowood WPC, by contrast, is engineered for a 20–25 year service life. The recycled wood fiber and high-density polymer core resist rot, moisture, and UV degradation in ways that timber simply cannot.
Maintenance: The cost nobody talks about
A 25sqm area of wood decking can cost up to £150 per year to maintain. Over a decade, that's more than the initial material cost. WPC requires zero maintenance — no sanding, no oiling, no sealing.
Moisture and rot: Where timber fails
Timber absorbs water, swells, warps, and rots. Pressure-treated pine resists decay longer than untreated wood, but it's still vulnerable — especially in high-humidity environments.
Necowood WPC absorbs less than 0.2% water. It doesn't swell, doesn't warp, and doesn't provide a food source for mold or fungi. It's 100% termite-proof and rot-resistant.
UV stability: Color that stays
Timber fades. Pine turns grey within 2–3 years. Thermally modified wood and bamboo follow a similar trajectory, requiring regular oiling to maintain appearance.
Necowood's 360° Shield™ ASA co-extrusion delivers Grade 4-5 color fastness under ISO-105-A02 — meaning no visible fading for 10+ years. It retains 90%+ of its color after 5,000 hours of QUV testing.
Price: Upfront vs. lifetime cost
WPC costs more upfront — $200–$800 per square meter versus $300–$350 for pine. But the total cost of ownership tells a different story.
Why designers and homeowners are switching
The verdict
If you're looking for the cheapest option today, pine will get the job done — for 5–8 years, with annual maintenance.
If you're designing a space that needs to look good, perform consistently, and require zero ongoing work, the choice is clear. Necowood WPC delivers a 25-year lifespan, zero maintenance, 100% pest resistance, and 10+ years of color stability — all with up to 90% recycled content.
