Durability
Larch is a class 3 durability rated product, which is moderately durable but can be treated to increase lifespan.
Dimensional Stability Larch will absorb and discharge moisture to reach equilibrium with the surrounding atmosphere and although fairly stable, can be prone to warping and shrinkage if not correctly acclimatised before application. Larch has a movement rating of medium.
Workability Larch can be machined to achieve a high quality finish, but due to the density of the product regular sharpening of the blades is recommended.
Fixing It is suggested that screwing instead of nailing is preferable to avoid splitting.
Coatings and Treatments Due to the density of larch, a high quality surface coating can be applied. We would recommend a factory finish to ensure an even colour as site application onto larch can cause colour variances due to the density variations between different sections. Larch can also be treated with standard treatment products and fire retardant systems.
Weathering Larch will weather to a grey colour if left untreated over a period of time.
Certification Siberian Latch is FSC certified.
