NORclad Siberian Larch Timber Cladding
Siberian Larch timber cladding is a durable specie with the sapwood omitted. It is a slow grown high density, softwood with a colour that ranges from a light straw yellow to a gold/brown in the heartwood area.
Siberian larch is one of the most durable species of coniferous softwood and comes from Siberia in Russia. It is one of the hardest and strongest commercial softwoods, excellent machining properties, though knots may be troublesome, and is suitable for many end uses from external joinery and cladding applications, areas of potential high impact damage such as schools, shops to boat planking.

Grades
All grading information is given as general guidance, to meet the criteria set through CE marking, quality and grading requirements.
Siberian Larch timber cladding will colour down if it is not protected as soon as installation is complete with a good quality semi or fully translucent UV-radiation protective coating. It also comes in two different quality grades:
Siberian Larch A
- FSC Certified, sustainably sourced Timber
- Imported from Russia
- All timber is sourced and machined to CE Quality Grading Requirements
- Kiln Dried to 14-20% Moisture content
- Typically 4.0m lengths
- Average knot diameter: 40mm. Commonly referred to as Unsorted (Grade I-III)
Siberian Larch B
- FSC Certified, sustainably sourced Timber
- Imported from Russia
- All timber is sourced and machined to CE Quality Grading Requirements
- Kiln Dried to 14-20% Moisture content
- Typically 4.0m lengths
- Average knot diameter: 60mm. Commonly referred to as Sawfalling (Grade I-IV)

Specify
If you have decided that Timber Cladding is going to be one of the materials on your project the next step is to create a specification that will meet the criteria and expectations you, and your client have.
NORclad will be happy to talk through what is available and enable you to select, amongst others: species, profile, size, treatment, requirement for Euro Class B, service life.
We offer installation guidance, detailing guidance based on TRADA documentation, with a wealth of knowledge and information on how different timbers will perform over the life span of your project.
Considerations that should be made when it comes to weather, along with how elevation and design variations can impact timber cladding.
