Mountain Resort Feuerberg
4,500 square metres of relaxation
Mountain Resort Feuerberg is not only energy efficient but also offers a high degree of comfort – all thanks to SWISSPACER ULTIMATE
Sparkling lakes, enchanted forests and impressive mountain landscapes adorn Austria’s southern province of Carinthia. Just below the summit of Gerlitze Alpe at 1,769 metres above sea level lies the exclusive Mountain Resort Feuerberg. To enable the resort’s guests to relax and feel good all around, it was down to the architect Ronacher to consider everything down to the tiniest detail – including in the building constructed in 2019, a light-drenched bathing house. Choosing the right window structure played a decisive role when it came to comfort in the new wellness temple: It had already been decided during the planning stage to go for the triple-glazed unit CLIMATOP XN – fitted with the warm edge spacer bar SWISSPACER ULTIMATE, which has a very positive impact on energy efficiency and indoor comfort.

Since its opening in 2007, Mountain Resort Feuerberg has received numerous awards and excellence certificates. It was recently voted one of the Top 10 wellness hotels in Austria by the Relax Guide 2020, and rightly so: The premium location within striking distance of hiking trails and ski slopes, the culinary offering and the extensive wellness programme make Mountain Resort Feuerberg one of the top destinations for wellness and indulgence in Austria. The resort’s impressive alpine spa covers an area of 4,500 square metres. There are twelve pools and a solar-heated alpine meadow lake, sixteen relaxation rooms, eleven saunas and a water slide.
The central design element of the new bathing house is an elliptically shaped swimming pool with a circular dome structure made from wood. Together with the therapy facility, it connects to the resort's existing buildings. The entire architecture thus becomes a semicircle that nestles back into the slope. At the front it traps the sun and opens up the panoramic view of the mountains. At the same time, this shape ensures sufficient protection against wind and weather in the courtyard.
“In each of the 15 construction phases that we have been able to realise for the Hotel Feuerberg in recent years, wood plays a supporting role in the truest sense of the word,” says the architect Dr Herwig Ronacher. He and his architecture firm stand for ecological construction, energy efficiency and specifically for building with wood. When it comes to energy-efficient construction, the company has implemented numerous structures and completed two research projects, one of which focused on energy-efficient swimming pools made from wood.
Building in an energy-efficient manner is very important for indoor pools. The basic shape of the ellipse and the wooden dome meet this need, as they give the building a very favourable ratio of volume to surface area.

The so-called “Concert Sauna” offers a fantastic view, thanks to the eight metre-long panoramic window. Singing bowl performances, concerts and other events are held here.

SWISSPACER spacers prevent cold bridges and heat loss in the area around the edge of the panes of insulating glass.
A 25 metre-long infinity pool is one of a total of 13 different bathing options within the resort.

Warm edge spacer bars from SWISSPACER prevent cold bridges and heat losses in the area around the edge of the panes of insulating glass – which prevents heat entering the building’s interior in summer and keeps the cold out in winter.
