Teal Windows and Doors Timber Species
Teal commonly uses Papua New Guinea Rosewood, Kwila and Western Red Cedar which are the market leader in performance and durability. Other timbers such as Accoya®, Surian and the Australian species (Blackbutt, Spotted Gum, Rosegum), can be used for specific applications and settings.
Timber is a natural resource and therefore no two pieces are the same. The Western Red Cedar, Spotted Gum and Blackbutt examples below show two samples of each of these species depicting the differences that can occur in the grain.
Papua New Guinea Rosewood
Teal Windows will manufacture almost any product from PNG Rosewood. This timber is remarkably stable with little natural movement and a low shrinkage rate. Timber is very oily which helps give it a very good durability rating and widely used for external joinery and luxury furniture items. PNG Rosewood is a hardwood species mainly grown in Papua New Guinea. Reforestation is a common practice where the removal of trees is occurring. PNG Rosewood is highly prized in Asia and thus only small quantities are available for the Australian market. Timber takes well to staining, oiling and most other finishes.
Kwila / Merbau
Teal Windows has been manufacturing windows and doors for many years from Kwila. Production quantities are increasing with its popularity in the joinery market and the addition of Bushfire-prone areas into the Building Code of Australia. (AS 3959-1999) Kwila is the best all-round timber to be used in fire-rated areas due to its availability, durability, stability and many other qualities. Kwila has a very high durability rating and is excellent for manufacturing windows and doors and many other joinery items such as furniture, outdoor settings, shop fittings, flooring, decking and cabinet making. Kwila is a hardwood species and grows in the Pacific Islands, South East Asia, Papua New Guinea and Northern Queensland.
Western Red Cedar
Western Red Cedar combines form and function like no other timber or man-made material. Its unique, natural performance characteristics and exceptional beauty bring warmth, character and longevity to homes and commercial building around the world. It is this set of properties that makes “Cedar” the timber of choice for discerning architects, builders and homeowners around the world. It is lightweight and easy to handle and install for both the professional and DIY persons. Western Red Cedar offers enormous versatility. It is a supreme green building material, producing fewer greenhouse gases, less water and air pollution and requires less energy to produce than alternatives and comes from a renewable and sustainable resource. Three Western Red Cedar trees planted to every one tree harvested. This means there are more Western Red Cedar forests in Canada today than there were 100 years ago. Timber has 400 times better insulation value than steel, 2000 times that of aluminium, 8 times that of concrete.
Spotted gum is one of Australia’s premium native hardwoods with a striking appearance and a high degree of natural durability and strength. Architects and designers throughout the world value spotted gum timbers for their back-sawn grain structure, attractive markings and vibrant colour palette. Spotted gum is generally grown along the east coast of Australia, from northeast Victoria to the northern tablelands of Queensland. The species may vary in appearance but not in durability class or other properties. Heartwood ranges from light brown to dark red-brown hues. Sapwood is usually white to light brown in colour. Some timbers have the presence of a wavy grain and can sometimes show an attractive fiddle-back figure. Also known as Lemon Scented Gum.
A strong, durable and beautiful Australian hardwood, Blackbutt has an even texture and a relatively straight grain. The heartwood ranges from golden yellow to pale brown, although occasionally a slight pinkish colour may be present. Gum veins may also be visible. The sapwood, which is not always easy to distinguish, is much paler in appearance. Blackbutt is readily available in New South Wales and Southern Queensland.
Rose Gum, also known as Flooded Gum, is a large fast-growing popular Australian hardwood timber. As the name suggests the heartwood produces a warm coloured timber with pink hues that are deep without being too dark, however, the sapwood is paler and not always clearly differentiated from the heartwood. It is grown predominantly on the East Coast of Australia from Newcastle on the NSW Central Coast to Bundaberg in Southern Queensland. The grain is fairly straight and the texture moderately coarse, this delightful timber with it’s a mix of soft pinks and peach tones may sometimes manifest insect trails and pinholes only adding further to its uniqueness and beauty.
Surian, also known as Calantas grows in Malaysia, Indonesia, the Philippines and Papua New Guinea. Its texture is moderately coarse with a grain that can be straight or interlocked. The heartwood is reddish-brown and the narrow sapwood is mostly pale red and distinctive. It is similar in odour and appearance to Australian Red Cedar. Teal Windows is very selective to what is manufactured with this timber.
