Do you need underlay for vinyl flooring?

Floors under 4mm thickness should not be installed with an underlay

Even thin vinyl is very durable, and all comes with a base layer for minor cushioning and moisture management. Particle board has been a common underlay in the past, however we don’t recommend it as it is not necessary and it has very little structural strength.

When would you need an underlay?

There are two main reasons you would need to add underlay to your flooring. If you’re installing it over a concrete subfloor with moisture concerns, you can use a vapor barrier that will not add any cushioning. If the subfloor is very uneven, you may consider a plywood underlay.
