External Walls
External Wall
The existing exterior wall made of wood cord was provided with a combination of interior and exterior insulation during the refurbishment. Behind a wall paneling made of silver fir is the 5 cm thick interior insulation, which is also used as an installation level. The vapor retarder was intentionally designed behind it, allowing for a penetration-free vapor retarder layer. A 6 cm thick exterior insulation as well as the wind paper was applied on top of the existing 150-180 mm thick wood cord. The vapor retarder on the inside and the wind paper on the outside protect the wooden structure from moisture damage. The existing facade was completely removed and replaced with new two-layer shingles made of spruce wood.
The outer appearance of the historic building was preserved by placing the outer insulation level behind the shingle façade .

The box-type windows are fitted with architrave style lentel. The windows on the ground floor are six-part with transoms from the early 20th century.
The wooden windows were renovated and partly renewed or supplemented in the original way.

The box-type windows are fitted with architrave roofs. The eight-part transoms and built-in ventilation slides are typical for the Bregenzerwald of the 19th century.
During the renovation, the wooden windows were renovated and partly renewed or supplemented in the same way.

OTHER
The original crippled hipped roof was reconstructed in the second half of the 20th century into a ridge purlin roof and covered with Eternit. In the course of the renovation in 2011, the roof was provided with 32 cm of insulation and a new tile covering.
Except of three new roof windows on each side, a new roof covering and the installation of a solar plant, the roof remained mainly unchanged from the outside.

Many parts of the wooden beam ceiling between the basement and the ground floor had to be renewed. The existing beams were statically reinforced and provided with 16 cm of insulation.
The old floor coverings were removed, cleaned and reinstalled. In the course of this, an underfloor heating was installed.

In order to get rid of the moisture problem, resulting from a lack of waterproofing of the basement walls and the foundation in the basement, a surrounding drainage system had to be built.

HEATING
DOMESTIC HOT WATER
In the course of the renovation, a pellet central heating system with underfloor heating and a solar system were installed. The two tiled stoves in the former restaurant rooms were also repaired. The elaborate yellow stove with blue-green decoration is by the way a production of the well-known bregenzerwald Hafner family Geser.
Originally, the building was heated exclusively by the two tiled stoves in the inn's dining rooms. For a modern and comfortable use of the building, the installion of a heating system was therefore required.

In the course of the renovation, a solar thermal system was installed on the south-facing roof to provide hot water.
The solar paneels are located above the economic wing, which faces away from the street, and is therefore hardly visible from the street.

In the course of the renovation, a pellet central heating system with underfloor heating was installed. The two tiled stoves in the former guest rooms were also repaired. Incidentally, the ornate yellow stove with blue-green decoration is a production of the well-known Geser family of stove makers from the Bregenzerwald.
