Brandschutz im Hochgebirge

Planai is part of the Schladming Vier-Berge-Schaukel, Austria’s biggest ski area, with 115 kilometres of piste and 52 cable cars. Situated right next to the mountain gondola station, the Schafalm first opened its doors for the 2003 winter season.

The ski lodge is built in the simple style of a mountain farm – right from the planning phase, the builders and Salzburg architects Fritz Hauswirth & Partner felt it was important for the new building to blend harmoniously into the Styrian landscape. The stylish lodge, owned by brothers Heinz and Reinhard Schütter, invites winter athletes to enjoy the restful and restorative atmosphere. A special feature, visible through the restaurant’s glass wall, is a sheep pen (Schafalm), from which the lodge takes its name. Decorated with local materials, the interior architecture has been transformed into an authentic ambience.

Challenging roof

While building the Schafalm, the roof presented a special challenge. Firstly, it had to be able to withstand the extreme winter weather at over 1,800 metres altitude. Secondly, the building is right next to the Planai six-man gondola cable car and there was a risk the cable could be damaged if the roof caught fire. To protect the cable in case of fire, the ski lodge needed an especially fire-resistant roof made with PAVATEX over rafter insulation: roofing membrane PAVAFLEX DSB 2, 15 millimetres of GKF plasterboard fire protection, double planked, two 80 mm thick PAVATHERM timber boarding as well as an ISOLAIR base board, 22 mm. The final top covering was constructed with a roof sub-frame base construction for the copper tiling of the Alpine roof.

Cold, heat, fire protection

Since the insulation is continuously laid, uninterrupted by the rafters, the PAVATEX over rafter insulation guarantees optimal cold protection and achieves a U-value of 0.26 W/m2K. With its high mass and the special structure, PAVATEX timber insulation can also store radiating heat. Severely diminished and seasonally lagged, this also provides excellent protection against summer heat. Because of the integrated plasterboard fire protection, the specially adapted PAVATEX over rafter insulation was able to raise Schafalm’s fire protection value from F30 to F60 – "high ignition insulated". This was documented in a test certificate from the IBS (Institute for Fire Protection Technology and Security Research) in accordance with ÖNORM B 3800, section 2 and section 4.

Natural Insulation

Ecological factors played a major part in the choice of materials. PAVATEX timber insulation meets the highest requirements for building biology and allows for a healthier interior climate. In addition the open diffusion, but airtight construction provides optimal moisture exchange of the individual roof building materials, eliminating the need for chemical wood protection. The builders chose PAVATEX products because their building partners, Gera-Bau and Knauss Building Management, already had good experiences with them. Thanks to the PAVATEX over rafter insulation, the roof beams and the old wooden face work combine to create a cosy ambience on the upper floor. Altogether the Schafalm can house approximately 250 guests. The large, heated terrace with side glazing as well as three large portable screens offer an addition 250 comfortable seats in any weather.
