Composite vs PVC. Honest comparison.

Capped composite has a wood-content core (recycled wood flour, bamboo, or hardwood fibre mixed with HDPE or PVC plastic) wrapped in a polymer capstock. Cellular PVC has no wood at all — the core is foamed PVC (PVC with dispersed air cells for weight reduction) wrapped in a PVC or PMMA capstock. Functionally both install identically with the same hidden-clip systems and the same joist spacing. The capped composite gives you a more natural wood-grain look; the cellular PVC gives you a cooler-running, mould-proof board with stronger scratch resistance. Examples of capped composite: Trex Transcend, Eva-Last Apex PLUS. Examples of cellular PVC at TUDS: Fiberon Sanctuary, Eva-Last Pioneer.

Yes — by roughly 5–10°C on a same-colour comparison in direct summer sun. The wood content in composite gives the board more thermal mass, which absorbs and retains more solar radiation than the foamed cellular core of PVC. That said, the colour you choose matters more than the material. A light grey composite will run cooler than a dark espresso PVC. For full-sun south-facing decks where bare-feet barbecues are non-negotiable, choose PVC and a lighter colour to stack both effects. For shaded yards, the heat differential is largely irrelevant.

On warranty paper, PVC carries the longer headline numbers — 50-year, lifetime, and 25-year fade warranties are common on premium PVC lines. Premium capped composite typically warranties 25-50 years residential. In practice, both modern capped boards (composite and PVC) outlast most homeowners' patience for the deck design itself — a properly installed deck of either material in 2026 is engineered for 30+ years before any visible degradation. The longer-lasting material in any given yard is the one whose chemistry matches the environment: PVC for pool decks and shade, composite for standard backyard sun. Full breakdown in the comparison table above.

Worth it when one of these is true: your deck has continuous chemical or moisture exposure (pool, hot tub, salt-air), your yard is permanently shaded (north-facing, mature tree canopy), you want the most photorealistic exotic-hardwood look currently available (PMMA-cap PVC like Eva-Last Pioneer beats every capped composite for Ipé realism), or the deck must be cooler underfoot for kids and pets in full sun. Not worth the premium when: you have a standard south-facing backyard with normal traffic and you're choosing a wood-grain colour. In that case the $1,500-$2,500 saved on a 320 sq ft project covers the railing or buys you better fasteners.

Sometimes — but increasingly, no. Older PVC boards were obvious: monochromatic, plasticky-looking, uniform sheen. Modern PMMA-capped PVC (Eva-Last Pioneer, AZEK Vintage) uses multi-tone photorealistic printing that beats most capped composites for hardwood realism. The only reliable test is to lift the board: PVC is noticeably lighter than capped composite of the same dimensions because the core is foamed. Capped composite has the heft of wood; PVC has the heft of dense plastic. Walk the swatch wall at either TUDS showroom and you'll feel the difference in 30 seconds.

Both modern capped boards are rated for normal residential traffic — patio furniture dragged across them, dog claws, bicycle tires, BBQ-tool drops. PMMA-capped PVC (Pioneer-tier) carries the highest cap hardness in the category and is the most resistant to micro-scratches that show in raking light. Standard PVC capstocks and premium composite capstocks (Apex PLUS, Trex Transcend) sit at similar real-world performance. Where both materials struggle: dragged metal furniture legs, dropped grill grates, ash from a fire pit on a hot board. Use felt pads, lift-don't-drag, and keep open flame off any deck surface. Both will outperform pressure-treated and most softwood options on every scratch axis.

PVC has a structural advantage on paper: zero wood content means zero moisture absorption, which means zero risk of freeze-thaw cold-crack failure. That said, every modern capped composite TUDS stocks has been Prairie-tested through -42°C cold cycles, and we've never paid a cold-crack warranty claim on any line we've sold. Eva-Last's bamboo-PVC hybrid sits closest to PVC on the cold-crack chart because bamboo absorbs less moisture than wood flour. Trex and Fiberon both perform reliably on Prairie installs. Bottom line: pick from a quality brand and you're safe in any Saskatchewan winter — PVC is just incrementally safer, not dramatically.

Yes — but only as visible feature elements, not as the main field. Mixing different boards in the deck surface itself runs into expansion-coefficient mismatches: composite and PVC expand at slightly different rates with temperature, which over time can cause uneven gaps or surface tension at the seams. Where mixing works: PVC for pool-edge or stair-tread boards (where the chemistry advantage matters most) with capped composite for the broader field, or PVC fascia and trim around a composite surface. If you're considering a hybrid build, talk to one of our Escape Artists at either showroom — we'll work through the expansion math with you and spec the right gapping.
