Siberian Larch, larix sibirica also known as meleze de siberie, sibirische larche LAGM, AS.It has a straight grain, a fine, uniform texture and is rather heavy with an average density of 590Kg/m3 at 12% Moisture Content drilling is recommended. Used extensively for cladding & decking applications as it is falls under durability characteristics Class 3 according to BSEN350:2016. Care has to be taken when selecting & applying coatings as larch is resinous. Use annular ring shanks stainless steel on all claddings, face fixing where applicable on external cladding to minimize the risk of boards popping out of fixings and use stainless steel decking screws for deck boards. It is important to note that larch has a tendency to split on the surface when exposed to the elements.Timber quality we supply is AB Grade Kiln dry Average 18% Moisture content which is equivalent or better than the standard Grade of Class 2/3 given in BS1186-3:1990 section 4 Class 2/3 of which class 3 is traditionally considered adequate for cladding and decking applications. This is considerably a better quality to the Saw falling S/F I-IV Grades found in most timber merchants. Knots are a present feature in the product and grade and should not be considered a defect.Stains tend to show easily including surface mould if not cleaned or maintained well. Regular cleaning is recommended depending on use and exposure as a minimum once a year to minimize slip risk from build-up of debris more frequency is recommended for horizontal areas e.g decking surfaces. It is always advisable to order 10% more to allow for waste due to trim or crosscutting loss.
