Benefits of Siberian Larch

Siberian Larch Grading

Millworks Grade B/C

Millworks B/C Grade timber features a blend of clearer boards alongside those with knots. This grade arises from the natural cutting process and the way the timber “falls” from the saw, resulting in a diverse array of characteristics within each board and providing unique visual appeal. 

Versatile aesthetic: The combination of clear and knotty sections provides visual variety, making it suitable for a wide range of design applications. 

Natural character: The presence of knots adds charm and character, enhancing the overall look of the timber. 

Diverse applications: Each board’s unique features allow for flexibility in usage, accommodating different project requirements. 

Millworks B/C Grade timber is ideal for cladding projects that require a balance of affordability, aesthetic diversity, and practicality. 

Siberian Larch Applications

In addition to our standard planed finish, surface texture can be added to create accentuated depth to the timber grain. Surface textures are recommended when coatings are applied to improve performance and enable enhanced adhesion and longevity.

  • Compatible with FineSawn, Milltex®, Burned.

Factory Coatings

In the correct conditions, Siberian Larch will weather to a silver-grey, if left untreated. Although naturally durable, Siberian Larch can be finished for protection against the elements. Millworks offers a range of factory coatings that serve both decorative and protective purposes, producing consistent results with a range of aesthetic options to suit your project.

  • Compatible with MillCoat® and OrganoWood®.

FRX fire retardant can be pressure-impregnated into Siberian Larch under ISO-controlled conditions to meet national Building Regulations for Euroclass B or C compliance.

Installation

Specifying the correct fixings is critical to the performance of timber cladding. Specifically manufactured  systems compatible with Millworks timber cladding and decking profiles, designed to ensure optimal performance of the timber and factory coatings. 

  • Compatible with MillFix®.
