Terrace Siberian larch 1st B quality
Siberian larch in 1.B or AB quality is available mainly because, compared to genuine Siberian larch in 1st quality, it is cheaper. This is the material that most contractors offer as "standard". This material is recommended mainly for decks where a larger amount of knots and resin are not bothersome. With this quality, heartwood is also permitted in the wood, and the wood is usually only air dried (without kiln drying). Such wood is usually used for "larger" terraces, where material consumption is high, mainly because of affordability and easy availability. However, for projects where aesthetics and long service life are important, we prefer to use 1st quality. We do not sand Siberian larch in AB quality (except upon explicit request). Compared to 1st quality, due to the amount of knots, the amount of resin, the permitted heartwood, and higher moisture content, it is more prone to cracking, which leads to a shorter service life (compared to 1st quality) and increases the possibility of splintering. Such material is also grown on plantations, as market demand is very high. Consequently, the wood has a looser growth pattern, which likewise negatively affects durability. We do not claim that the material is unusable, but in our opinion, for the production of high-quality products it is less suitable.
