The joint between floor boards can make a surprisingly large difference in flooring style, but it is often overlooked. There are two main choices available to you:
Square edge boards lay flush against each other with little or no gap between the boards leaving the surface smooth. As well as beingan attractive option for contemporary spaces, square edge floors are also easy to clean as they leave nowhere for dust to collect.
Square edge floors can work particularly well in smaller rooms as the smooth, simple surface will not give the floor too much detail and spoil the aesthetic.
Bevel Edge (or V Groove) floors have a small angle cut from the edge of boards which, when the floor is installed, leaves a small gap between each board. This adds depth and definition to each board, highlighting their unique qualities. Remember that beveled floors can reinforce traditional style if this is a part of your design.
Bevelled edges come in different widths, referred to as maxi, mid and micro-bevel, to give a more or less pronounced joins between boards.
There are also 2V and 4V bevelled floors. A 2V only has bevelled edges down the 2 long sides of each board while the ends (header) square edge sit flush together. 4V boards have a bevel around all 4 sides. These different styles can really change the look of your floor, so think carefully about what kind of bevel will best suit your space.
As a general rule, try using pronounced bevelled edges in larger rooms where the definition of the boards will help them stand out individually and not blur together as you look across the room.
