Australian Chestnut
Technical Information:
Australian Chestnut Flooring is characterised by subtle colour variations from mellow straw brown to light chocolates. Durable eucalyptus are blended to provide a sophisticated, natural beauty to any interior.
Australian Chestnut Flooring is hard wearing and durable and is also one of the most beautiful and timber floors produced in Australia.
A suitable coating can be applied to enhance the grain and protect the floor, making it easier to maintain. Australian Chestnut Floor requires minimal maintenance and is the perfect choice for busy lifestyles.
Australian Chestnut Flooring will not collect dust or conceal dirt, making it a natural choice for asthma and hay fever sufferers.
| Botanical name: | Quercus alba |
| Origin: | South Eastern States of Australia |
| Trading names: | Australian Chestnut Northern White Oak, Southern White Oak, True White Oak, White Oak,Southern Blackbutt |
| Heartwood: | Pale yellow-brown to mid-brown, sometimes with a pink tinge |
| Sapwood: | Light coloured |
| Texture: | It is mostly straight grained with a medium to coarse texture |
| Grain: | Usually straight but sometimes wavy, producing a fiddleback figure |
| Growth Rings | Large distinctive growth rings and some medullary rays may be present. |
| General comments: | Manufacturing: Needs much care in drying because of proneness to collapse and internal checking, as well as surface checking on the tangential surface. Reconditioning is standard practice. For good-quality boards it is usual practice to quarter cut the logs. |
| Common Uses: | Australian Chestnut is used for a wide variety of purposes from construction to interiors. Due to its interesting and prominent grain pattern Australian Chestnut is a popular species for flooring, and in Australia is used mostly for this purpose and for joinery and furniture. |
| Average Hardness Rating - Dry Hardwood: | Between 7 and 8 |
Notes:
Density: 'Green Density' (GD) is the density of the wood at the time the living tree is felled. It varies considerably with the season, weather conditions, the age of the tree and so on; the quoted figure must therefore be accepted as a guideline only and when accurate green density figures are required for, say, assessment of transport costs, it is advisable to carry out accurate determinations on the materials involved.
'Dry Density' or 'Air Dry Density' (ADD) is the average density of the wood at 12 per cent moisture content. It too varies with conditions of growth, climate and maturity of wood.
There are published figures for both Green Density and Air Dry Density of most commercial species.
The figures given above have been rounded to the nearest 50.
Hardness rating: The hardness rating of a timber species is measured by the Janka Test. This is a standard test which measures the penetration into the timber of a common load and projectile. The results relate to a hardness capacity of the material and are expressed in kN. This information is useful where the timber may be subject to potential damage from impacts e.g. a dance floor. There are 2 sets of published figures; one for 'Green' or freshly felled timber and one for seasoned timber - i.e. timber with a moisture content of 12%.
The ratings given here are:
Soft - less than 5.5
Moderate - 5.5 to 7.0
Hard - 7.1 to 10.0
Very Hard - greater than 10.0.
Lyctid susceptible sapwood: Only the sapwood of some hardwoods is susceptible to lyctid borer attack. No softwoods are susceptible to attack.
Natural durability ratings: The natural durability rating of a timber species is a rating of the timber's resistance to attack by wood destroying fungi and wood destroying insects. The sapwood of all timber species has poor resistance and so the natural durability rating applies only to the heartwood of a timber species. The rating is based on the testing of stakes and poles embedded in the ground and on expert opinion of historical performance. There are 2 sets of ratings: one for above ground use and one for in-ground contact use. The lower the number the higher the performance in terms of durability. This information is useful for specifying material for external or exposed applications.
