Species & Coatings
Need help selecting the right timber coating for your project? Our comprehensive guide explains everything you need to know about finishes and how timber naturally varies in colour.
While we aim to reproduce colours as accurately as possible, we strongly recommend requesting product samples before making your final selection. Timber is a natural material, and each species has its own unique features and colour variations. Although we manufacture our products with consistency in mind, samples may not fully represent the variation that can appear across an entire project.
Please Note: Natural Accent – Clear Exterior only available on request for Spotted Gum.

Length Options
Timber battens are available in a range of length options to suit on-site needs.

Random Lengths
The most common form of timber supply with a length spread of 1.2m - 3.6m, with an average of 2.4m. Random length is supplied by default unless specified otherwise.
It is generally the most cost-effective way of procuring timber. All battens are supplied end-matched and must span across two clips. Battens are joined with our Sculptform Batten Joiner.

Set Lengths
Set length is used where a quantity of the same lengths are required for your project. Offered in lengths between 1.2m and 3.6m, set lengths are always supplied slightly over length to allow for onsite trimming.
Exact Length
Cut to exact length is similar to the 'Set Length' option, but with trimming to an accuracy of ±1mm. Accurate onsite measure required to prevent issues with uneven walls and ceilings.Cladding Screw Types
Sculptform supply a quality stainless steel screw to be used for timber substrates with all timber cladding orders. A tough 304 stainless steel, the screw is designed to predrill and countersink in one easy motion. Sculptform can supply tek screws for steel substrates.
Wood Screw
304 grade stainless steel. #10g x 40mm ‘The Piranha’ – Self drilling with brown e-coat painted head.
Tek Screw
Galvanised tek screw #8g x 30mm.
Trims and Details
Aluminium Trims
L Profile
The L-Profile is used at wall ends, divider between the cladding and another material, against window frames, bottom of walls and many other applications.
T Profile
Available in Natural Anodised (this can be powder coated to virtually any colour), the T-Profile was designed so large walls could be broken up into sections, creating breaks along the facade.
Base Details
Vertical Cladding
Sealing the end grain well is a critical detail to ensure the long-term constitutional and aesthetic integrity of the cladding. If the end grain is not correctly sealed, water will soak up the end grain causing the timber to expand, mould to grow, and blackness to appear.
Horizontal Cladding
The aluminium starter piece is used at the bottom of the wall so that the first board can be concealed fixed. The trim is used when running your cladding boards horizontally, and is designed to fit into the groove of the Tongue & Groove Cladding profile.
End Matching
Standard end matching can be used with all profiles and performs the role of creating a neat, seamless linear effect. End Matching was designed so boards could be joined off-stud, a time and labour-saving innovation that removes the need for measuring and cutting on the stud. End matching slashes wastage from 10% to less than 5%*, and the design facilitates water run-off when used vertically.
The installation method for end-matching is the same whether the cladding is vertical or horizontal. Quality sealant needs to be applied to gap, then boards are pushed together. Excess sealant to be scraped off once dry.
Horizontal Cladding on Blockwork
For interior applications, batten centres to be at 600mm centres.
Horizontal Cladding on Studs
Interior studs spaced at 600mm centres. Exterior studs spaced at 450mm centres.
Vertical Cladding on Blockwork
For interior applications, batten centres to be at 600mm centres.
Vertical Cladding on Studs
Interior battens spaced at 600mm centres. Exterior battens spaced at 450mm centres.
Curved Walls
First ensure the framing is set-up suitably, to allow for curved fixing battens. The centres of the stud work may have to be reduced excessively, depending on the radius. With curved walls it’s better to limit the board size to one of smaller width, particularly if the radius is tight.
Careful attention must be paid to the distance between the opening of the tongue and groove in external application. When the opening creates waterproofing concerns, run a sealant down the groove during installation and neatly cut off excess once dry.

Maitland Riverlink
The architecture is intended to act as a civic set piece in a street full of great buildings with enduring materials. It also must have a strong architectural form to register as a landmark when viewed from the levee bank, from neighbouring Lorn and the Belmore Bridge. We imagined a ‘sculptural gateway’ in which the material scale, grain and texture was consistent on all sides of the frame, even though the ceiling and walls couldn’t have been constructed from the same material.
