The Thorogood Difference…

Our slow grown Siberian Larch comes from only the top grade selected butt logs found just beneath the tundra line of the artic circle. The tough, hardy trees from which our timber is harvested have survived some of the toughest conditions on earth and the wood that comes from them is equally durable. Unbelievably dense and sporting tightly packed annular rings, these long wide lengths of waney edged timber boast a narrow sap band mild, straight timber.


One of the most decay-resistant species of timber available and demonstrating unusually high durability for softwood, Siberian Larch is popular for any external use that needs to be hard-wearing and long-lasting. Versatile and attractive, with heartwood that varies in colour from red-brown to dark brown or pale yellow and a grain that can be straight or spiralled. Larch’s growth rings present interesting patterns and character that can be revealed and enhanced with plain sawing. The timber finishes well and its fine texture is known for its slightly oily feel and distinct resinous scent when working.

Working Properties

Larch works well both with machine and hand tools and can be easily worked to an extremely smooth finish – though it is worth noting that it tends to be knottier than other durable softwoods such as Douglas Fir and red cedar. Care must be taken when machining due to larch’s high density, which has a tendency to dull cutting edges, as well as the wood’s natural resins which can cause saw blades to become congested. After machining, larch’s naturally prominent grain tends to pucker up bringing texture and interest, particularly in slow grown examples.

Physical Properties

Siberian Larch’s high density renders the wood extremely strong, stable, and hard-wearing after drying - however the timber can be prone to splitting when fixed with nails and so screwing is recommended over nailing to avoid this.


Siberian Larch is naturally resistant to disease and rot, demonstrating excellent waterproof capabilities that make it very popular for outdoor use. Its high density and strength also makes the wood extremely hard-wearing and particularly useful for areas of stress, wear, or exposure.

Larch’s natural water-resistance makes it perfect for boat building while its hardwearing timber and fine finish also means it can often be found as the track surface in velodromes.
