Wood flooring underlay is a really important part of your wood flooring project.  The ideal way to create the perfect laying surface for your new floor, a good quality underlay will not only make your floor easier to lay, it’ll keep it looking great longer too.  Add to this, the thermal and noise insulation properties provided by a good quality flooring underlay and you really start to see how important it is to make the right choices.

There are various types of underlay intended for use with wood floors and the choice you make will depend on many things, but in any case, your wood flooring supplier will be able to guide you.  Here are some of the different types available:

Foam underlay. Foam underlays are particularly lightweight and come in a variety of thicknesses as well as (most) offering some sort of moisture barrier.  Suitable for most types of wood flooring, foam underlay is one of the most commonly used underlay options.

Damp-proof underlay. Although most underlays contain a small degree of damp proofing qualities, an actual damp-proof underlay will provide the ultimate protection against moisture passing from your sub floor to your wood floor.  Particularly useful in basement projects, damp-proof underlays come in a range of gauges and your wood flooring supplier will help you choose the most suitable for your project.

Noise reducing underlay. If you live in a flat or apartment or are concerned about noise pollution within your own home, the best way to put your mind to rest is to invest in a soundproof underlay.  Ranging from a relatively fine 2mm thickness, this option exists up to a thickness of over 5mm and can be used for all types of wood flooring.

Insulating underlay. Insulating underlay is a bit like duvets and comes with a Tog rating.  Lightweight and particularly helpful when it comes to combatting cold and keeping your heating bills down, the side-effect of insulating underlay is that it will also help reduce noise and make your under foot experience more enjoyable.

Adhesive underlay. Adhesive underlays are specifically created for use with solid wood flooring.  With a removable film, they are specifically intended to reduce the time taken to install your new floor.

Under floor heating underlay. As you’d expect, when you have under floor heating, it’s important not to reduce its effectiveness by choosing the wrong underlay.  It is for this reason that there is a whole range of wood flooring underlays that are made to ensure maximum heat transfer at the same time as offering all the other benefits of a quality underlay.

Which underlay you choose will depend upon your own unique circumstances, and because you’re at the point of installing a new wood floor, it’s the ideal time to take advantage of the advice on offer from your wood flooring supplier.

If you’re ordering online, you’ll need to work out how much underlay to order.  It may sound really obvious, but you’ll need to order the same amount of underlay as you have flooring.  If you’re struggling to work out how much flooring and underlay you’ll need, this article will help at how to measure your room.
