Description

Millworks source all ThermoWood® Pine from carefully selected International ThermoWood® Association members. Thermal modification enhances the wood’s natural attributes resulting in a timber that boasts impressive stability and improved durability suitable for a wide range applications, profiles and finishes.

ThermoWood® Pine is dark brown in colour throughout, with recognisable round and butterfly-shaped knots. The thermal modification reduces the woods’ ability to absorb moisture, resulting in a board that is less prone to warping, twisting, or cupping.

Millworks C Grade timber features prominent knots, grain variations, and other natural characteristics that are crucial for maintaining the integrity of the board. These visual characteristics are not a reflection of durability or quality. This grade is ideal for projects that wish to showcase the timber’s natural beauty with visible grain pattern and texture.

Surface texture

Planed.

Guidance for specification option:

For uncoated finish options only.

Brushed.

Guidance for specification option:

Recommended with all MillCoat finish options. This surface texture is recommended for improved coating adhesion. A wire brushing process is used to pull away softer wood fibres, enhancing the natural grain pattern and leaving a textured surface.

Mokuzai 'Charred'.

Guidance for specification option:

Recommended with MillCoat Charcoal Black Mokuzai ‘Charred’ offers a durable finish with the look of heavily charred timber.

MillSawn.

Guidance for specification option:

Recommended with all MillCoat finish options. Mokuzai MillSawn provides a more defined and textured alternative to traditional fine-sawn timber with increased definition.

Manufacturer guidance

Surface texture can be dependent on finish chosen. Please see each surface texture guidance.
