Siberian larch is particularly durable and resistant to adverse weather thanks to its closely-packed growth rings, and is therefore an ideal wood for outdoor use. It copes with ease with frost, snow, storms and hot summer temperatures. The wood smells aromatic, is very firm, dries quickly and is resistant to fungal attack, which means it is very skid-proof. Owing to its excellent durability, larch wood can even be used untreated for outdoor projects. Siberian larch is the hardest coniferous wood and is classified in durability class 2-3 according to DIN EN 350-2. Decking boards made of Siberian larch also appear very light and friendly due to their expressive textures and vibrant colours, and are a visual highlight in any garden structure. We furthermore offer joists and supporting timbers to make your construction project easier, which are likewise made of Siberian larch. Do you need some advice on how to process and place your new larch boards? If so, you’ve come to the right place! For 1m2 you will need approximately 7 lineal metres of decking boards and roughly 2.3 lineal metres of joists.
