Insulate the wooden house with suitable materials

One of the advantages of wood as a material is the good insulating properties that it already has. Nevertheless, of course, additional heat and sound insulation must be installed. Ideally, the insulation materials complement the properties of the wooden house. This means that very good energy values are combined with a high level of living comfort.

Multi-shell is a prerequisite

If you want to fulfill your dream of a single-shell log cabin made of whole tree trunks, you can't do much more for insulation than plugging the cracks as insulation. The large cross-sections of the wall trunks provide the basic insulation, which can also be sufficient in the Nordic climate. Many Scandinavian wooden houses prove this up to the vicinity of the Arctic Circle.

In Germany, a wooden house usually consists of multi-shell wooden structures. There is a choice of cladding the wooden beams from the outside or inside. Accordingly, the thermal insulation is installed between the supporting timber structure and the cladding. In the case of wooden panel constructions, interior cladding made of particularly inflammation-resistant materials is sometimes required for fire protection reasons.

Properties of common natural insulation materials

Before a wooden house is built, the formwork structure and insulation should be determined in the planning. With plank and log houses, the wood look is often appreciated inside and outside and should not be clad. For this requirement there is the option of using halved logs with a space in between.

Ventilation must be ensured with every insulation. Plastics such as styrofoam, construction foam and other diffusion-sealed insulation materials are not suitable. Natural insulation materials also maintain the pleasant and special room climate in the wooden house. The most common natural insulation materials are:

cork

Cork can be used both in sheet form and as bulk material. A pleasant side effect is the low price of shredded wine corks, which are available in eco-friendly shops.

Wood wool and wood fibers

The relatives of the construction material also have disadvantages. Wood wool and fibers can get moldy and do not meet the fire protection requirements in every form.

Perlite

Lava stone pebbles, which are particularly noticeable due to their light weight and do not store water.

Hemp and flax

Is available in pressed sheet form or as fiber and bundle goods.

cellulose

Only permitted to a limited extent, as the shredded paper can go moldy.

Sheep wool

The luxury insulation material is very expensive and especially recommended for the corners of houses that require intensive insulation.
