Important properties of Siberian lorx tongue and groove board

  • This profile has a tongue and groove. The longitudinal sides are provided with a chamfered side. When pushed together, this creates a V-shaped groove. Other common names for this profile type are tongue-and-groove, tongue-and-groove boards, planed and plowed parts or roof boarding. Note: always install horizontally with the tongue upwards so that no water can run into the groove.
  • Working width: 135 mm
  • The planks are sorted on one visible side, the rear contains possibly some local planing errors, tire marks and/or roller marks.
  • The production reserves the right to deviate a maximum of 3-4% from the head size, in order to be able to plan a nice, straight and dimensionally stable product. In addition, humidity can affect the head size (dry and warm weather causes shrinkage).
  • We supply wood at trade length. This means: not sawn square and not shortened to length, often with some excess length.
  • Dry cracks can be seen on the short sides. Always calculate at least 10 cm extra sawing loss in length.
  • Correct installation is very important. Good ventilation, sufficient framing and correct fastening are required. Before you start, read our mounting tips and instructions carefully!

Siberian Larch

Siberian Larch is a type of wood that comes from Russia. It is a popular and widely used wood species in Europe. It is straight and easy to process. Siberian Larch can be used in various outdoor projects and is affordable compared to tropical hardwood.

Compared to the European variant, Siberian Larch has smaller knots and a finer structure. This makes Siberian Larch the highest quality Larch wood species. Because these trees grow in a colder climate, the wood has a higher density and durability than European Larch. Façade cladding and wall cladding are popular applications, but the wood is also used as a decking or garden partition.

Siberian Larch originally has a warm golden-yellow hue, which will gray evenly over time. This is in contrast to European Larch, which is characterized by its salmon-pink colour. Especially the typical drawing of the wood provides the warm and charming appearance of these planks. The wood has small knots between 1 and 2 cm.

  • Easy to work
  • Durability class 3
  • Beautiful small flames
  • Suitable as facade cladding, wall cladding and decking

Siberian Larch is a type of wood that is easy to use to work. The planks and beams must be pre-drilled before bolting. In addition, we always advise to use stainless steel screws and fasteners, this prevents stains on the wood. We do not recommend gluing, because shrinkage stresses occur with this wood.

Note: Deep milling, sawing lengthwise or sawing again can expose stresses. These stresses may have arisen during drying and processing. This is one of the reasons why we recommend adding 10% wood to your order. This way you can be sure that you have enough material to work with.

This profile has a chamfered side and a chamfered side, making it easy to slide into each other. A tongue and groove is also commonly referred to as a bevel siding. It is important that the tongue is always mounted upwards so that no water can enter the groove.
