Siberian Larch Cladding

Siberian Larch is becoming a very popular cladding timber due to its natural durability and attractive light appearance.
Whilst not offering the same contemporary clear look as cedar, Siberian Larch cladding prices of about £22.00 per square meter can be very appealing when comparing to cedar which is about £36.00.
Larch quality varies greatly but we have achieved a reliable supply from the Lake Baikal region of Siberia where the best Larch logs are to be found.
All of our Larch is FSC Certified and of a consistent grade.

Extra care is needed when using Siberian Larch cladding, Benchmark Timber have the experience to ensure the quality of your project.
Sapwood can be a problem with Larch as it is not durable - We take care when milling to ensure all sapwood is on the rear of the cladding board.

Larch cladding can move and shrink – when we mill we ensure all tongues are at least 15mm to make sure the tongue stays in the groove while the timber moves.

We take care to buy from sawmills who store in such a way to minimise the potential for fungal staining.

Please also consider Western red cedar which is the premium cladding timber offering greater natural durability and dimensional stability.

Thermowood may also be worth considering which offers similar properties to cedar at a lower cost. Thermowood can be quite knotty.

Please see our Profiles page for details of the types of Larch Cladding we can mill

The Tree and Forest

Larch is a dense and hard. The Siberian Larch grows as the name suggests in central Siberia where there are about 600 million acres of Forest half of which is Larch. Stocks of standing timber are increasing which means this is a sustainable resource.

Larch cladding may split during nailing so pre drilling recommended.

We supply a mix of grades 1 to 111 which is equivalent to U/S grade.
This it a good quality grade but has a greater number of knots than our Cedar.

Siberian Larch must be used with care to allow for movement & therefore minimise the risk of splitting.
