One of the most appealing aspects of timber is its natural aesthetic, however, it is important to remember that as an organic material, variations are inevitable. The descriptions on this page are designed to help you understand how your order will look, and avoid any unexpected surprises.
The biggest factors which influence the aesthetic of the timber are the grade and the colour variation. Timber is graded depending on the visible features present, placing the timber into one of three grades. Timber colour variation provides variety and a natural look to a feature wall or ceiling, but it is important to understand the range of colours each species can provide.
At Sculptform we grade our timber as per the Australian standard, AS 2796.2-2006. The grades specified in this relate to aesthetic features within the timber, such as knots and gum veins. To achieve the best combination of timber’s natural charm and consistency throughout a project, we guarantee each order maintains a strict ratio of a minimum of 2/3 select grade and 1/3 Standard grade.
Each batten or board that goes through our factory is hand-graded in accordance with the standard, and designated into one of three grades –
Select grade timber contains the least amount of visual features, providing the cleanest look at the expense of the timber’s natural variation.
Your Sculptform order will consist of a minimum of two-thirds Select Grade timber.
|Gum Veins of less than 250mm in length and 2mm in width are acceptable.||Tight Knots of less than 15mm in width are acceptable.|
|Borer Holes are acceptable provided there are less than 10 holes per 900mm depending on width.||Checking is acceptable provided individual length does not exceed 250mm and width does not exceed 1mm.|
Standard Grade timber offers a more natural aesthetic by providing timber containing larger and more frequent features. These features provide the timber with ‘character’ and emphasise the natural look and feel. Your Sculptform order will contain a maximum of one-third Standard Grade Timber.
|Gum Veins of less than 1m in length and 5mm in width are acceptable.||Tight Knots of less than 40mm in width are acceptable.|
|Borer Holes are acceptable provided there are less than 24 holes per 900mm depending on width.||Checking is acceptable provided individual length does not exceed 250mm and width does not exceed 2mm.|
High Feature Grade
Sculptform does not use High Feature Grade timber in our orders.
Timber battens or cladding of the same species can vary greatly in colour and grain. The beauty and character of timber come from this variation, as no two trees grow exactly the same. Certain aesthetic features are more common in certain species, just as some species are more consistent in colouring than others. Our selection of coatings can help provide more consistency over a project, or help bring out the natural variation.
The below examples are the be used as a guide, and other variations will certainly occur. Please view our project gallery to see examples of timber variation in completed projects.
Spotted Gum has a wide range of colours depending on the location of the source forest. Ranging from light brown through definite browns to deep red-brown hues. It can also have patches of white to light brown colours running through it up to 50mm wide. Spotted Gum is a moderately coarse and uneven textured wood with some timbers having the additional feature of a wavy grain, giving rise to an attractive fiddleback figure.
Wallan Veterinary Hospital uses Spotted Gum coated in Clear Oil to create this amazing facade.
American White Oak is pale yellow-brown to mid-brown, sometimes with a pink tinge. It is mostly straight grained with a medium to coarse texture, and with longer rays and more figure than Red Oak. It has large distinctive growth rings and some medullary rays may be present.
The Sir Zelman Cowen Centre For Science uses White Oak coated in Clear Poly for this stunning timber feature.
Blackbutt has an even texture. The grain can be interlocked but it is generally straight, making it appealing for interior use. It ranges from golden yellow to pale brown, although occasionally a slight pinkish colour may be present. Small borer holes are common along with gum veins.
Pale to pink straw, Victorian Ash features a moderately coarse texture and has a predominately straight grain, although it may be wavy in parts resulting in a fiddle back appearance. It will provide a light, creamy-coloured timber for appearance applications. Excellent for taking stains.
