Flooring Underlayments

Flooring underlayments do more than “add a pad.” The correct underlayment supports your floor system, helps manage sound transfer, and can provide vapour planning over concrete (system dependent). At Squarefoot Flooring, we help homeowners and contractors compare options for laminate, engineered hardwood, vinyl plank, tile, and more across Ontario.

Start with the job: sound, moisture, or stability

Pick the performance you actually need

• Acoustic underlayment: helps reduce footfall noise and echo in condos and multi-level homes (product dependent)
• Vapour and moisture control: often required over concrete slabs and basements (system dependent)
• Compression resistance: protects locking joints by preventing “spongy” movement (product dependent)
• Thermal comfort: some systems help reduce the “cold floor” feel on concrete (system dependent)

Choose by flooring type

Compatibility is the ranking factor and the warranty factor

• Laminate underlayment: choose an approved pad with the right density, and plan vapour control for slab installs when required (system dependent)
• Engineered hardwood underlayment: common choices include acoustic foam or felt styles for floating installs when approved (product dependent)
• Vinyl underlayment (LVP/LVT): many floors limit thickness and softness, especially with attached pads, so use only manufacturer-approved underlayments (product dependent)
• Tile underlayment: tile needs a stable, tile-rated layer such as cement board or an uncoupling membrane like Schluter systems (product dependent)

Popular underlayment brands customers ask for

Ontario-friendly systems for real jobsite conditions

• QuietWalk underlayment: fibre-based options often chosen for sound control and moisture management (product dependent)
• DMX underlayment: dimple membrane styles commonly used for basements over concrete (system dependent)
• Roberts underlayment: practical pads for common floating floors (product dependent)
• Husssh underlayment: acoustic-focused options for condos and upper floors (product dependent)
• Schluter underlayment: uncoupling and waterproofing systems for tile installations (product dependent)

Common mistakes to avoid

What to confirm before you buy

• Do not stack extra underlayment under floors that already have attached pads unless the brand allows it (product dependent)
• Underlayment does not level a subfloor; fix dips and seams first with the right prep materials
• Over concrete, follow moisture testing and vapour control requirements (system dependent)
• For radiant heat, confirm the full floor + underlayment system approval (product dependent)
