Solid ash timber board: what is it?

Ash is characterized by a clear, coarse grain pattern. The colour comes close to a pearl appearance that changes from white/pinkish to yellow when exposed to daylight. If you treat ash wood well, it will last for years. Ash is not to be confused with Maple, which is soft and has a minimal grain pattern. It is advisable to sand the board well before finishing it with stain, varnish or oil. This way you can be sure that you are finishing the original wood colour. Keep in mind that solid ash wood warps. This makes it less suitable as doors, but all the more suitable for furniture or displays.

European Ash is a wood species that is relatively flexible and resilient. In addition, ash wood is strong and is therefore a popular wood species for making frames and furniture. Think of (wall) panelling and tabletops. Ash can be stained well and is very suitable as a substrate for a varnish.

Quality grading with timber board

Timber board comes in different qualities. This does not mean that the sheet is more or less strong, it indicates the quality of the appearance of the sheet . The quality can be found in the product properties. More information about the visual grading below.

Ash is supplied in different visual qualities. A/B describes the appearance of the sheet and therefore has nothing to do with the structural strength of the material. The term A/B means that the top side of the sheet has visual quality A and the underside has visual quality B. This means that the top is almost completely free of knots. Occasionally, there may be a small knot here and there, but it will be no larger than 4 millimetres. The underside has visual grading B and can therefore have a somewhat coarser appearance. Here, knots of up to 7 millimetres are allowed. The heartwood and sapwood of the beech differ little.


Lumber Quality Indication
A Uniform colour. No knots and no heartwood allowed.
B Small colour nuances permitted. Tassels and heartwood may be present.
C Large colour nuances permissible. Tassels and heartwood are present.

The solid sheet material is made up of slats. Slats are small wooden planks made entirely of pure wood. To be able to make a sheet of a larger size, several slats are combined into one large sheet. This results in a very solid and strong sheet. Keep in mind that no slat has the same appearance. The wood structure and colour of each slat is unique and can therefore also deviate from the image. Our solid sheets are interior bonded, which means that the material can only be used indoors.

The direction of the wood grain

Timber board has a visible wood grain. The wood grain pattern always runs in the longitudinal direction. When sawing the sheet, we maintain that the longitudinal dimension is also the longitudinal direction of the wood grain. So be careful when filling in the measurements, so that the flames of the wood grain all run in the right direction!

Available thicknesses of solid ash timber board

Solid timber boards can be ordered in various thicknesses. You can easily specify your desired thickness during the ordering process. This way you can be sure that the sheet material meets your requirements: both the size and thickness of the material. The following thicknesses are available: 26 mm and 40 mm.

Machining solid ash timber board

European ash can easily be sawn, milled or otherwise machined. This type of wood is easier to machine than, for example, beech wood. The wood is easy to sand and is a suitable substrate for a coloured stain or varnish. Because of its grain, the use of sharp tools is recommended. Ash boards are easy to assemble using nails and screws. However, pre-drilling is recommended because it is a hard wood species, but this is not necessary.

Ash can warp in humid conditions and discolour when exposed to too much daylight. Therefore, before use, make sure you sand this sheet material and apply a good varnish, stain or oil. Is your stain or varnish available in a UV-resistant version? Choose this so that the wood discolours minimally after finishing.

Specific applications of solid ash timber board

Ash is ideally suited for applications such as doors, door frames, stairs, walls and furniture. We do not recommend using the material outdoors, as it can warp. When solid wood is exposed to temperature differences or is used in humid areas, there is a high probability of discolouration or deformation of the board.

Alternatives to ash timber board

Is Ash not the right type of wood for your project or are you looking for a variant that is more robust and darker? Then opt for solid timberboard oak or solid timberboard mahogany. View our other solid wood types below:
