For a standard thickness of a terrace board of 27-28 mm, we recommend laying beams in increments of not more than 500 mm, to avoid deflection and “walking” of the board, as well as to create the required number of attachment points. If for some reason the distance between the lags exceeds 500 mm, we can offer a terrace board of greater thickness.
Yes, preferably at least 5 mm, this is necessary to compensate for dimensional changes caused by changes in temperature and humidity. In addition, this contributes to good ventilation to the back of the board.
In our nomenclature we do not contain these products. At the same time, we strongly recommend using Plank or Rhombus (Bevelled plank) for cladding facades. In addition to being modern and allowing the architect-designer’s fantasies to “wander off,” thanks to its use, excellent ventilation of the facade is ensured, and dimensional changes due to changes in temperature and humidity of the environment are compensated. Visually it looks no worse, but in our subjective opinion it’s even much better)) than imitation of timber, block house, lining …
It is highly advisable to use larch for a number of reasons:
Planken can be compared to lining. But the lining, with all its aesthetic advantages, has a significant drawback: the lining boards are connected to each other in a spike groove. Such a compound very poorly tolerates the swelling and drying of wood with moisture differences at the interface. Sheathing boards begin to warp, twist, swell, and if necessary, replacing any of them can be difficult to separate from the rest, since the stud connection is sewn to the wall tightly. Planken boards are not laid in a spike, but end to end or at some distance from each other. Such ventilated facades from planken (ventilation facades) are more reliable under the influence of variable external conditions without loss of stability of the entire structure.
