Selflok Weatherboards have a super simple self locking system that aligns every board perfectly. Precise routing gives the product a beautiful and unique ship lapped profile which has become the all time Weathertex favourite.
Selflok Colonial Smooth board is a CodeMark accredited weatherboard that has a smooth flat surface finish. The 300mm board contains two 40mm grooves. The groove begins rather deep at 5mm. Gradually, as the groove progresses, the depth decreases, eventually meeting with the smooth surface.
- Made from real Australian hardwoods.
- Off stud joining option enables minimal waste and less timber stud layout
- Can be cut with standard carpentry tools
- Can be used internally (group 3) and as an external wall cladding in bushfire attack levels up to and including BAL 19 construction.
- Curved walls can be achieved down to a minimum 2.5m radius for Selflok.
