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 durability as cedar, Siberian Larch does have a price advantage of about £22.00 per square meter, comparing to cedar which is about £36.00 per square meter
Siberian 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 goods are FSC Certified and of a consistent grade.

Extra care is needed when using Siberian Larch, 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 once the board has moved.We take care to buy from sawmills

 

who store in such a way to minimise 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 is can be quite knotty.

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