Do you need underlay for your floor?
Underlay is the layer between your subfloor and a floating floor. Get it right and the floor is quieter, warmer underfoot, and protected from moisture. Get it wrong and you can void a warranty or fail a condo sound inspection. Here is the short version.
Laminate
Almost always needs underlay — unless it is thick 14mm or has an attached pad. In a condo or over concrete, step up to the 3mm black (moisture barrier + condo-grade quiet) or 5mm airflow.
Vinyl (SPC/LVP)
Usually already has a pad attached — do not add a second one. Only bare vinyl with no attached pad needs a thin underlay. Not sure? Ask us your SKU.
Basement / concrete
Moisture is the risk. The 5mm airflow bubble pad lets the slab breathe and lifts the floor off surface moisture, while soundproofing at IIC 72.
Still unsure? Tell us your floor and where it is going — we will tell you the exact underlay your SKU needs, no guessing.
Underlay & Moisture Barrier
Sold per full roll. Underlay is mandatory under floating laminate — it soundproofs, cushions, and (on the 3mm black + 5mm airflow) blocks moisture from concrete or below-grade subfloors.
Our pick — quieter underfoot with a built-in moisture barrier. Best for condos, upper floors & basements. 200 sqft roll · IIC 72 / STC 73.
Budget standard laminate underlay. 200 sqft roll · IIC 52 / STC 66.
Max moisture protection — dimpled air-gap for concrete/basement subfloors. 100 sqft roll · IIC 72 / STC 73.

Flooring accessory FAQ
Do I need underlay for laminate flooring?
Yes. Floating laminate almost always needs a separate underlay unless the plank has a pad already attached to the back. Underlay cushions the floor, quiets footsteps, and — on our 3mm black and 5mm airflow pads — adds a moisture barrier. The only common exception is thick 14mm laminate or any board that lists an attached IXPE/pre-attached pad in its specs. If you are in a Markham condo or a basement over concrete, use the 3mm black or 5mm airflow underlay so you meet condo sound requirements and block subfloor moisture.
What underlay is best for a condo?
For condos we recommend the 3mm black acoustic underlay. It is rated IIC 72 / STC 73, which comfortably clears most Toronto condo board sound-transmission requirements, and it includes a built-in moisture barrier. It is a small upgrade over standard 2.5mm white foam but it is the one that keeps you onside with the building.
What underlay do I need over concrete or in a basement?
Over concrete or below grade, moisture is the enemy. Use the 5mm airflow bubble underlay — its dimpled air-gap design lets the slab breathe and lifts the floor off any surface moisture, while still soundproofing at IIC 72 / STC 73. The 3mm black is the step-down option if height is tight.
Do I need underlay for vinyl plank flooring?
Usually not. Most vinyl (SPC/LVP) sold today comes with a pad already attached to the back, and adding a second pad under it (pad-on-pad) can void the warranty and make the floor feel spongy. Only bare vinyl with no attached pad needs a thin underlay. If you are unsure, check the plank spec or ask us and we will tell you exactly what your SKU needs.
How many pieces of quarter round or baseboard do I need?
Estimate the perimeter of the room (roughly 4.5 × the square root of the floor area gives a safe number for a not-perfectly-square room), then divide by the length of the piece — quarter round and baseboards come in 10ft sticks. Add a little for cuts and corners. Add your floor to the cart first and our buy box will suggest a starting quantity automatically.
Can I buy accessories without buying flooring?
Yes. Everything on this page can be added to your cart and ordered on its own — underlay, quarter round, shoe moulding and baseboards. Pick up free at our Markham showroom or add delivery at checkout.
