Physical properties of Kiln Dried Siberian Larch
Heartwood is variable in colour ranging from light straw, pinkish brown to brown.
Kiln dried : 800kg/m3
Larch cladding may split during nailing so pre drilling recommended.

This it a good quality grade but has a greater number of knots than our Cedar.
Larch may also have the occasional sap pocket
Siberian Larch must be used with care to allow for movement & therefore minimise the risk of splitting.
Larch heartwood is naturally durable when left untreated
High natural resistance to rot & fungus
50 year expected durability if untreated
Suitable for architectural timber cladding and decking.
Siberian Larch cladding will slowly weather to a grey colour. If this is not desired then treat with a Alkyd resin based stain.
