Assemble the wooden facade - lath constructions with insulation

When installing the wooden cladding on the outer wall, the substructure made of battens forms the fastening of the entire structure. The battens must provide sufficient stability and match the dimensions of the insulation layer.

Slat dimensions

The basic volume for the installation of the wood façade is wooden slats in size of 30 times 50 millimeters. They are spoiled at a distance of 600 millimeters to the outer wall. Place the latest exactly with the help of a spirit level.

Optimal slatted dimensions

  • 30 millimeters x 50 millimeters
  • 40 millimeters x 60 millimeters
  • 60 millimeters x 60 millimeters
  • 60 millimeters x 100 millimeters

Install insulation under the panel

Under the new wooden façade, you can install a thermal insulation. The insulation layer is incorporated between the slats of the basic tranquility. Depending on the nature of your outer wall, the insulation layer can be up to 140 millimeters. The dimensions of the slats must be adapted to the dimensions of the insulation.

Fixing the wooden cladding

After attaching the base battens to the masonry and incorporating the insulation, you have applied the permeable film to the insulation. The now final external formwork or wooden cladding is mounted on a supporting battens. Depending on the thickness of the wooden boards, the slats must have an average dimension of at least 24 millimeters by 48 millimeters. The boards of the wood cladding are ideally at least 18 millimeters thick. They should be a maximum of 200 millimeters wide. With these dimensions, they are equally suitable for horizontal and vertical mounting.

Tips & Tricks The wood cladding can be installed horizontally or vertically. Vertical slats make the house appear higher. Install the tongue and groove formwork so that the grooves do not point to the weather side. Precipitation flows off particularly well on the vertical battens.
