Species Description

Siberian Larch is the premier softwood when it comes to cladding. Its natural attributes make it ideal for external applications as its durable, stable and dense which provide excellent weatherproof performance. Siberian Larch is slow grown and a light straw colour with a dynamic grain pattern and is available in two grades, Unsorted and Sawfalling but we describe our stock as A Grade and B Grade for ease. A Grade allows for occasional small knots (up to 5p size) but many of the boards can be clear of defect. B Grade allows for frequent knots and some larger knots up to the size of a 50p.
