Fire and ice: New tramway Streubödenbahn - equipped for all challenges with ADLER Pyrolan

The construction proposed by local architect Thomas Fliri makes perfect use of the properties of wood and wood-based materials: The workshop prefabrication that this made possible guaranteed the required short construction time on site over the summer season. At the same time, the opportunity was taken to create a new appearance and renew the structural image of the mountain railroad - the exterior and interior surfaces are unmistakably characterized by the use of wood. Larch wood shingles were used for the weathered façade parts of all three station buildings, and the wall parts in the covered platform areas were structured accordingly. This made it possible to avoid unfavorable sound reflections in the halls and at the same time take fire protection into account: Architect Thomas Fliri tendered the wooden surfaces coated with the ADLER Pyrolan Expand system - and in a particularly elegant design. Black-coated wood fiber boards were placed in front of vertical slats at a distance. Both the black base surfaces and the almost natural-looking slats made the Pyrolan treatment suitable for use in the cable car stations.

Foam protects

Pyrolan Expand from Austria's leading paint manufacturer ADLER is a foaming (intumescent) water-based fire protection coating. When exposed to high heat, a carbon-containing foam forms on the surface, which acts as an insulating layer against the ignition source. This drastically reduces the speed at which the fire spreads, significantly increasing the time available for escape and extinguishing. By coating with the ADLER innovation, timber components achieve the highest possible fire protection class B-s1, d0 for combustible materials such as wood. This means that they only make a limited contribution to a fire and meet the strictest criteria in terms of the amount of smoke released and possible burning droplets/fall-off. In addition, the coating structure is completely water-based and free of formaldehyde, biocides, heavy metals and halogens - so no toxic substances such as formaldehyde are released in the event of a fire.

Safely beautiful

The wooden elements were manufactured and installed by Fieberbrunn local hero Holzbau Foidl: "The vertical slats against the dark background look really great," says Thomas Foidl enthusiastically. The opaque version of Pyrolan Expand in a rich black was used for the spruce wood panels behind them. The spruce strips were coated in a colorless finish to preserve the natural look of the wood. The spray coating process not only guarantees a visually perfect surface, but also an even application quantity for reliable fire protection. The people of Fieberbrunn leave nothing to chance - and so, after a construction period of just eight months, the winter season kicked off on December 7, 2024 with the opening of the Streubödenbahn!

ADLER – paint runs through our veins

With 730 employees, ADLER is Austria's leading manufacturer of varnishes, paints and wood preservatives. Founded in 1934 by Johann Berghofer, this family business is now managed by a member of the third generation, Andrea Berghofer. Every year, 21,000 tonnes of paint leave the Schwaz plant and are delivered to customers in more than 30 countries worldwide. ADLER has sales subsidiaries in Germany, Italy, Poland, the Netherlands, Switzerland, the Czech Republic and Slovakia; their sole production site is the ADLER-Werk Lackfabrik in Schwaz, Tyrol (Austria). ADLER was one of the first companies in its sector to be 100% climate-neutral (since 2018). The company has been able to reduce its carbon footprint to a minimum through a wide range of measures. ADLER offsets any unavoidable residual emissions through the purchase of recognised climate protection certificates, thereby helping to finance new climate protection projects
