Vinyl Flooring

If you're fitting a cushioned vinyl flooring that provides plenty of padding and a soft surface, you might not need underlay.

Laminate Flooring

Laminate floors are considered "floating floors" and are generally not permanently fitted to your home's floor. This type of flooring will need underlay to provide support for the laminate, as well as to protect it from moisture. If you're installing laminate directly on to a concrete floor, you will need a product with an in-built moisture barrier to prevent damp ruining your new flooring.

If you're installing laminate over wooden floorboards, however, you'll find a wide range of regular underlays are suitable for the job. You will need to bear in mind any special conditions in your home; for example, if you have underfloor heating installed, you'll need a product suitable for this purpose. Likewise, if soundproofing is a priority, select an option specially designed to stop excess noise.


There is a wide range of underlays suitable for use with carpet, and the best option for you will come down to the type of sub-floor, your carpet's thickness and your budget.

Polyethylene is generally the most affordable and is a good budget option if this is a priority. Traditional underlays are made from rubber, and while this is still available, it's a less popular choice than in the past.

Polyurethane is now one of the most popular options and is manufactured from thermally bonded foam for a tough and durable finish.

 Engineered Flooring

Similarly to laminate flooring, engineered floors are usually considered floating floors and aren't generally fixed to the sub-floor. This means many underlays suitable for use with laminates can also be used with engineered flooring. Just bear in mind the point above about requiring a built-in moisture barrier if installing on a concrete floor. Why not browse our site for more information?
