New England Oak Hardwood Timber Species Spec.

Timber Species: New England Oak (Manna Gum)

Hardwood Timber Species: New England OakGrowing straight and tall, the New England oak can reach heights of around 40 meters with recorded trunks of over 3 meters in diameter. Native to southeastern Australia, this hardy tree can survive at temperatures of up to -15 degrees Celsius, making it suitable for planting in Europe.

With a rough bark that peels away in in long, thin ribbons from its highest branches, New England oak is an important source of nutrition for koala, sugar gliders, and other local arboreal marsupials. Most often also called manna gum because of the high sugar content of its sap, this tree might not be the most durable when it comes to woodworking – only being used rarely, most often when it comes to unseasoned or seasoned house framing – but it’s an exceedingly handsome timber that has been referred to as “classic” in its subtlety.

New England oak does tend to be rather soft, with just a 6 rating on the Janka hardness scale and an average dry density of 750 kg/m³. However, it’s an ideal timber for both solid timber flooring and parquetry thanks to the prominent growth rings in its variable grain and its even, medium texture. Tones are decidedly blond, with hues ranging from a rosy-pink brown to a soft yellow, and it’s common to have handsome streaks of light grey thanks to the natural variation present in any organic flooring product such as this easily workable oak.

Be aware though – this malleability does come at a bit of a price. New England oak isn’t exactly durable, and it’s also relatively susceptible to damage from insects like termites or lyctus borers. This makes this timber obviously not suitable for outside decking, even if treated, as wear-and-tear will take its toll on New England oak quicker than most other materials. Keep this timber inside and far away from the elements to best preserve its natural beauty.

Physical Properties

Dry Density:  750 kg/m³

Janka Hardness: 6 kN

These properties are only a guide, as timber is a natural product there will be variations within any species. The Janka Dry Hardness rating measures the hardness of the wood. The higher the number the harder the wood.
