Laminate flooring underlayment — acoustic, moisture, and subfloor smoothing

The right underlayment makes laminate sound better, last longer, and handle subfloor imperfections. YaleTown Floor stocks foam, cork, IXPE, and combination-membrane underlayments — from $0.30 to $1.20 per sq ft — with options that meet condo IIC 55+ acoustic minimums and include integrated moisture barriers for concrete subfloors. Shipped Canada-wide with free samples.

Underlayment types — which to choose

  • Foam (2–3mm) — Budget basic. Lightly cushions and reduces hollow sound. Best for plywood subfloors in single-family homes. From $0.30/sq ft.
  • Foam + moisture barrier — Adds a film vapor barrier under the foam. Required over concrete subfloors. From $0.45/sq ft.
  • IXPE — Crosslinked polyethylene. Better acoustic performance than foam; thinner profile (1.5–2mm); often integrated into premium laminate. From $0.60/sq ft.
  • Cork (3–6mm) — Best acoustic performance for condo IIC compliance. Naturally antimicrobial. From $0.80/sq ft.
  • Cork + rubber composite — Top-tier acoustic and moisture performance. Required by stricter condo boards. From $1.20/sq ft.

Underlayment purchasing concerns — solved

  • "Concrete subfloor moisture?" Required: any underlayment with integrated film vapor barrier, or separate 6-mil poly under foam.
  • "Condo IIC 55+ requirement?" 3–6mm cork or cork+rubber composite. Most foam underlayments don't meet IIC 50.
  • "Subfloor flatness?" Underlayment only smooths variations under 1–2mm. Self-level low spots over 3mm before installation.
  • "Already in my laminate?" Many premium laminates ship with attached cork or IXPE. Verify before ordering separate underlayment — doubling up can void warranty.
  • "Free shipping?" Free Canada-wide delivery on orders 1,000+ sq ft.

Frequently asked questions

Do I need underlayment if my laminate has it attached?
No — doubling underlayment voids most manufacturer warranties and creates excess softness underfoot.

Which is best for sound dampening?
3–6mm cork or cork+rubber composite — the only underlayments that reliably meet IIC 55+ for condo bylaws.

How much should I order?
Underlayment ships in rolls or sheets matched to room sq ft. Add 5–10% for trim cuts.

Concrete subfloor — what's required?
Integrated film vapor barrier or separate 6-mil poly. Without it, moisture migrating up from concrete can warp laminate cores.
