Length Options
Random Length - End matched

Random length end matched cladding boards utilise a method called end matching. This process creates a small tongue and grove on either end of the board to allow for stronger, straighter joins. Random end matched boards come in random lengths over 900mm and are the most cost-effective length option. This option allows for joining off a stud and is ideal for applications where the board length required is over 3-3.6m depending on species selection.

Set Length

Set Length boards are supplied all over a desired specific length. Different lengths are available for different species so please contact us for more information. This length option is perfect for applications where joins are not desired however the exact measurement is unknown allowing installers to trim on site

Cut to Exact Length

Cut to exact length boards are supplied each to desired specified lengths. This allows for much faster install time and avoids trimming on site. This option is only recommended for projects where exact measurements are known. Please note exact length boards have a tolerance of ± 1mm.

Fire Compliance
Group Rating

All untreated timber achieves a Group 3 rating according to AS 3837:1998. If Group 1 timber is required, two options are available –

  • Wide Timber Veneer or Timber-look Veneer Aluminium Click-on battens provide a timber aesthetic while achieving a Group 1 rating
  • Fireshield coatings applied on site can make timber Group 1 compliant. Sculptform does not factory apply Fireshield coatings. See more about Fireshield here.

 

Combustibility

Timber is deemed combustible under AS 1530.1-1994. If your project requires a non-combustible material, Timber-look Veneered Aluminium Click-on battens are a good alternative to solid timber.

For Class 2 and Class 3 buildings, concessions in the NCC allow for timber cladding to be used while remaining fire compliant. Read more about what makes Tongue & Groove Cladding a facade option for low-rise projects such as hotels and multi-residential buildings here.  

BAL Rating

Each timber species achieves different BAL ratings according to AS 3959-2009 as outlined below –

Timber Species Bal Rating
Banjo Pine 19
Blackbutt 29
Burnt Ash Not Compliant
Pacific Teak 19
Spotted Gum 29
Vic Ash Not Compliant
White Oak 19

Durability

Durability is an important factor when using timber externally. Each species of timber falls into one of the following durability classes. These classes relate to above ground durability as per AS 5604: 2005.

Timber Species Durability Class – Life Expectancy Usage
Banjo Pine Class 4 – Less than 7 years Interior Only
Blackbutt Class 1 – Greater than 40 years Interior / Exterior
Burnt Ash Class 1 – Greater than 40 years Interior / Exterior
Pacific Teak Class 1 – Greater than 40 years Interior / Exterior
Spotted Gum Class 1 – Greater than 40 years Interior / Exterior
Vic Ash Class 3 – 7 to 15 years Interior Only
White Oak Class 3 – 7 to 15 years Interior Only
Maintenance
Interior Applications

Interior timber typically does not need maintenance. It is important to regularly check timber which is exposed to UV radiation through windows etc, as this can lead to yellowing of the coating. Re-coating may be required.

 

Exterior Applications

The level of maintenance required on external timber largely depends on the degree of exposure, location, coating selection and desired aesthetic. Sculptform offers the following coating options factory applied as standard –

  • Clear Oil (Cutek CD50 Clear Oil)

When timber is not exposed to direct sunlight (for example exterior soffits), Clear oil maintains the timbers natural colour. When timber is exposed to sunlight, using Clear Oil will allow the timber to silver unless additional pigment is used to tint the clear oil. Sculptform recommends re-coating these applications every 12-18 months.

  • Enviropro Exterior Coatings

When Enviropro exterior coatings are used on timber which is not exposed to direct sunlight, it typically will not require maintenance. Sculptform still recommends annual inspections to check the integrity of the coating.

Enviropro coatings are designed to maintain timber colour and prevent silvering, even in areas which are exposed to direct sunlight and UV radiation. To keep the timber pristine, Sculptform recommends re-coating every 2-4 years. The rate of coating deterioration varies, so 6 monthly visual inspections should be carried out to identify any deterioration of the coating and areas for re-coating.

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.

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.
