20mm or 14mm Oak Flooring?

20th Mar 2013 @ 17:34

In the minefield which is oak flooring, there is many, many options available to you. One of the options which we provide is 20mm oak flooring and 14mm oak flooring. But what are the key differences and which should I choose?

Firstly its important to note exactly what 20mm and 14mm oak flooring is. Each individual board is made up of either 20mm or 14mm of solid oak wood respectively. Each board has been milled from a single piece of timber to create a full solid oak board, which is available in a range of different widths. Our 20mm and 14mm oak flooring both incorporate a tongue and groove structure as well as a grooved underside for maximum stability. Equally both of these are available in a number of different grades, ensuring there is a board for everyone.

So what exactly are the differences that would make you choose one over the other?

Our range of 14mm oak boards were created from a need to fit our flooring into the more challenging locations. One of the more common requirements nowadays is to replace carpet which has been laid over a plywood sub-floor with oak flooring and yet lose as little room height as possible. This is where our 14mm oak flooring is the perfect solution to just that problem. At 14mm thick the European oak is just thick enough to provide stable flooring, and yet thin enough to replace a carpet/underlay combination. This thinner cut of board also means that we can get more boards out of the same oak, which means a lower price to you!

For those who are looking for a completely traditional solid oak floor where room height is simply not a problem, our 20mm boards are the boards for you. Available in a large range of grades, including the ever popular classic grade, the 20mm boards are the perfect boards for the traditionalist looking for a thicker cut of oak flooring. For areas where room height or humidity is not an issue, our 20mm boards are perfect for creating that timeless appeal.

I’ve taken up a bedroom floor in the house I’ve just bought because it was chipboard. I now have exposed beams and would like to lay an oak floor but can only afford the 14mm boards. Would it be ok to lay 14mm boards as if they were floor boards or do I need to put plywood down first?

Hi Steve,

At 14mm thick, these boards do need to be laid over a wooden subfloor. These boards are designed for screwing or nailing either into an existing timber subfloor or a plyboard base.

Hope this helps.
