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 to help 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.

Sculptform Timber Variation

Timber Grading

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

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. 

Sculptform Timber Grading - Gum vein Sculptform Timber Grading - Knots
Gum Veins of less than 250mm in length and 2mm in width are acceptable. Tight Knots of less than 15mm in width are acceptable.

 

Sculptform Timber Grading - Borer Holes Select Sculptform Timber Grading - Checking Select
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

Standard Grade timber offers a more natural aesthetic by providing timber containing larger and more frequent features. These features provide the timber with unique qualities and emphasise the natural look and feel. Your Sculptform order will contain a maximum of one-third Standard Grade Timber.  

Sculptform Timber Grading - Gum Veins Standard Sculptform Timber Grading - Knots Standard
Gum Veins of less than 1m in length and 60mm in width are acceptable and less than 2mm in depth. Tight Knots of less than 40mm in width are acceptable.

 

Sculptform Timber Grading - Borer Holes Standard Sculptform Timber Grading - Checking Standard
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. 

Colour Variation

Timber battens and 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 throughout 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

Spotted Gum timber can range from light to medium browns, with red hues. Some white to very light brown colours can also run through it at up to 50mm wide. Colour varies greatly depending on the location of the source forest. Spotted Gum is a moderately coarse and uneven textured wood and can feature a wavy grain, giving rise to an attractive fiddleback figure.

American Oak

American Oak has a light to medium brown heartwood with slight pink undertones and sapwood in white to light brown tones. The grain is straight but with a coarse, uneven texture and large pores. It is rated as non-durable and can stain when in contact with water, particularly the porous growth ring areas.

Australian Ash

Australian Ash timber can range from a pale pink to pale yellow or brownish colour, providing a light, creamy-coloured timber for appearance applications. It features a moderately coarse texture and has a predominately straight grain, although it may be wavy in parts resulting in a fiddleback appearance. It is excellent for taking stains.
