About English Ash Sawn Timber
Prized for its beautiful appearance, toughness and flexibility, ash is the ideal wood for fitted and free-standing furniture. A native English species, it has been used for centuries in traditional furniture making and in more specialist applications such as sports equipment and car chassis. Its flexibility and straight grain make it one of the best woods for forming curved components such as the backs of Windsor chairs.
Appearance
Waney edge boards of ash will be supplied with wane (bark) on one or two edges.
The sap wood of ash is indistinguishable from the heart wood which ranges in colour from pale cream to light straw, with occasional small black mineral streaks.
The flat cut boards are particularly attractive because of their unusual flowery patterns while the straight grained centre boards, although less visually appealing, are prized for their workability and bending capacity.
Ash trees will often develop a barrel of darker ‘olive’ coloured wood around their heart which, in older trees, can develop to become a large proportion of the heart wood which is highly desirable because of its decorative properties.

Grading
English ash is available in the following grades but please note that not all thicknesses are available in all the grades:
First Joinery
This is our standard joinery grade where only occasional knots up to 40mm diameter are accepted. The grain may be slightly angled and some colour variation is likely. Larger knots and defects will be measured out. Centre splits are accepted but a suitable reduction in measure will be applied. Accepted: Grain deviation, occasional knots up to 40mm, olive colouring. Other isolated defects if measured out. Not accepted: Curly grain, rot, bark pockets, excessive worm attack.
Second framing
This grade is suitable for the frames of covered furniture where strength is more important than visual appeal. Knots and defects are accepted providing there is a good proportion of cutting available. Centre splits are accepted but a suitable reduction in measure will be applied. Accepted: All knots and defects. Not accepted: Rot, excessive worm attack.
Insect attack
Emerald Ash Borer feeds on the cambium layer between the bark and sapwood. This usually does not affect the heartwood.
Fixings
Stainless steel nails, Pre-drill boards to avoid splitting.
Fire
Euroclass F (Untested). D-s2, d0
