The Wood Properties

Ash Wood Advantages and Disadvantages

Ash Wood Advantages

  1. Appearance: Ash Wood has a typically straight grain and light-brown hue, It is wood that is very attractive and gives a uniform look. 
  2. Workability: Ash is relatively dense with good working and finishing properties. Its Janka hardness is medium. Therefore it holds the nail, screw, paint, and polish well. It can bend easily through the steam process.
  3. Versatile: Ash Wood is versatile and can be best durable for many applications. It is used to make furniture, smoke, toys, and sports parts. But white ash and black ash are the most common species used in furniture manufacturing.
  4. Shock Resistant: Janka’s hardness of Ash (White) Wood is 1320. Which is between the hardness of red and white oak. Due to enough hardness, this is the better option for flooring and roof construction. Ash hardwood floors are durable and shock-resistant.
  5. Durability: It is one of the most durable varieties and has been used in the United States for hundreds of years. If using Ash Wood for interior application and with little care, it lasts for several decades.
  6. Affordable/availability: Ash Wood is widely present around the world. Being easily present, transportation does not cost extra. Ash Wood is less expensive than other hardwoods with the same properties. The demand of the Ash Wood can be easily met in its bulk.
  7. Easy to maintain: If we talk about maintenance then it is easier to maintain than any other hardwood. If you have installed ash wood for a dry area, then it will need at least maintenance.
  8. Hardness: It has great hardness. Janka hardness of white Ash is 1,320 lbf (5,870 N), European Ash has 1,480 lbf (6,580 N), and  Mountain Ash 1,210 lbf (5,400 N).


  1. Open Grain: Open holes are found on the surface of ash wood. To get a sine and a smooth surface, it is very important to fill these open grains. You need to use grain to achieve smooth and shiny ash surfaces.
  2. Not good for exterior Applications: Ash is not receiving a good rating in terms of durability. It is well used for interior and dry space, but when used for soil contact applications such as fence, and decking. Therefore It is susceptible to attack by insects and fungus after exposure to soil, especially the sapwood.
  3. Poor stability: Ash is its ability to be bent. Due to the low density. It starts to bend after exposure to moisture. It should be used for dry and interior places to maintain its constant stability.
  4. Easily Split: Ash splits very easily when the deal and screw are applied. Hence pre-drilling is required for the screw.
  5. Fast burner: Fire is always a danger to wooden structures. It is more flammable. For this problem, you can do the chemical treatment.

Ash Wood Uses?

  1. Interior applications: Ash is heavy and hard. Therefore It is mainly used for furniture, cabinets, doors, and windows.  Due to its medium hardness, there is a good choice for flooring. It does not scratch and damage easily.

  3. Ash Wood has no taste and smell. Therefore it is used in making food containers.
  4. Due to its strong hardness and strength of European Ash (Janka hardness 1,480 lbf (6,580 N)), it is used to make sports parts such as baseball bats, hockey sticks, and tool handles.
  5. Since white ash is very easy to cut and curving, it is used to make boxes/crates and decorative items.
  6. Ash is also known as firewood. It has a low moisture content. Therefore it burns fast and easily. Ash is good with fish and red meats.

When ash wood comes in contact with moisture, wood expands and warps are causing structural problems. Somewhat pressurized treated lumber can withstand moisture.
