What's the difference between rigid core and flexible vinyl plank for Metro Vancouver homes?

Rigid core vinyl plank (SPC and WPC) and flexible vinyl plank are fundamentally different products, and for Metro Vancouver homes, rigid core is the superior choice in nearly every scenario. Understanding the difference will save you from a costly mistake, because the two products look similar on a showroom shelf but perform very differently once installed in our moisture-rich climate.

Flexible vinyl plank — sometimes called traditional LVP or peel-and-stick vinyl — has a thin, bendable PVC core that you can literally roll up or flex in your hands. It is typically 2mm to 4mm thick, installed with adhesive (glue-down) or peel-and-stick backing, and requires a perfectly smooth, flat subfloor because every imperfection telegraphs through the thin, flexible material. Dust, grit, old adhesive residue, or minor bumps in the subfloor will show as visible lumps and ridges in the finished floor. Flexible vinyl also expands and contracts noticeably with temperature changes, which can cause gaps, curling at edges, and seam separation — particularly in rooms near exterior doors or with large windows that experience temperature swings.

Rigid core vinyl plank comes in two formats: SPC (stone polymer composite) and WPC (wood polymer composite). SPC has a dense, stone-based core that is extremely rigid, dimensionally stable, and resistant to denting. WPC has a foamed wood-plastic core that is softer and more cushioned underfoot but slightly less resistant to impact and compression. Both are typically 5mm to 8mm thick, install as floating click-lock floors (no adhesive needed), and are vastly more forgiving of minor subfloor imperfections than flexible vinyl. The rigid core bridges small dips and bumps that would telegraph through flexible vinyl, and the click-lock system creates a tight, stable floor assembly.

For Metro Vancouver homes specifically, rigid core vinyl wins on several critical points. Moisture performance: both rigid core and flexible vinyl are waterproof at the surface, but rigid core's click-lock installation creates tighter seams that resist water penetration better than peel-and-stick or butt-joint flexible vinyl. In a city that receives over 1,200mm of rain annually, with basements prone to dampness and mudrooms that see daily water exposure, this matters. Temperature stability: SPC rigid core barely expands or contracts with temperature fluctuations, making it reliable in rooms with radiant heating, near exterior doors, or in sunlit rooms with large windows — all common in Vancouver homes. Flexible vinyl, by contrast, can curl, gap, or buckle with temperature swings. Installation speed and quality: floating click-lock rigid core installs faster and more reliably than glue-down flexible vinyl, with no adhesive dry times, no risk of adhesive failure, and easy replacement of individual damaged planks.

The one scenario where flexible vinyl still makes sense is commercial glue-down LVT professionally installed with full-spread adhesive — this is a premium product used in healthcare, hospitality, and high-end residential applications where the direct bond to the subfloor provides superior acoustic performance and a completely solid feel underfoot. But this is a professional installation requiring expert subfloor preparation, specialized adhesive, and skilled labour. It costs $8 to $14 per square foot installed in Metro Vancouver compared to $5 to $10 per square foot for quality rigid core SPC.

For the vast majority of Metro Vancouver homeowners, SPC rigid core vinyl plank in the 5.5mm to 8mm range with a 20-mil or higher wear layer is the right product. It handles our marine climate, tolerates subfloor imperfections better, installs cleanly, and delivers excellent long-term value.
