From solid-built house to dream villa with wood effect

In the Austrian town of Bad Dürrnberg, Hallein, architect Walter Scheicher has modernised his parents’ 48-year-old home, providing the solid-built house with a wooden facade and insulating the existing building fabric in energy-efficient fashion. In doing so, he placed his trust in the ideal properties of PAVATEX wood fibre insulating materials.

The solid-built house belonging to Gerlinde und Walter Scheicher and dating from 1962 was not sufficiently insulated, resulting, among other things, in high heating costs. So son Walter Scheicher – an architect by profession – developed an extensive restoration concept for the property. His plan was to install insulation boards on top of the existing Isospan blocks and to combine rhomboid cladding with white rendering on the exterior. When it came to insulation, he opted for PAVATEX products. “My roots are in the timber industry, as I trained as a carpenter before completing my university degree. So I have a particular affinity with this construction material,” explains Walter Scheicher. The architect also specialised in the field of energy-efficient construction at an early stage, helping to build the first multi-storey passive house in Salzburg. “I have been using PAVATEX wood fibre insulating materials in projects with great success for a number of years and have they have always come up trumps,” says the architect. The products boast optimum physical construction properties. The naturally good insulating value of timber is enhanced more than threefold thanks to the special PAVATEX manufacturing process. Timber‘s outstanding sorption capacity means that it is almost unrivalled in its ability to provide welcoming warmth, while its high level of insulation makes it energy efficient too. “Thanks to their high net weight, the wood fibre insulating materials also boast wonderful summer properties, thus ensuring a pleasant indoor climate during the summer heat. And when it‘s stormy outside, the insulating materials provide excellent acoustic insulation too,” says Walter Scheicher. The ecological credentials of the PAVATEX products are also impressive. The raw material is residual soft wood obtained from sawmills as wood chips and slabs. Unlimited resources of this renewable material are available, with PAVATEX manufacturing its insulating materials without additives in an environmentally friendly process to ensure that they are entirely free of pollutants.

More peace in a picturesque setting

Gerlinde and Walter Scheicher were looking for a peaceful as well as picturesque setting in which to spend their retirement, and moved into the house in quiet Bad Dürrnberg in 1995. The small health resort south of Salzburg belongs to the town of Hallein. The 5,500-square-metre family plot is situated at an altitude of 860 metres and offers fantastic views of Mozart‘s home town to the north and the delightful surrounding countryside.

Wood fibre for roof and wall alike

Restoration began in July 2009. Various PAVATEX insulating materials were used in the house, which offers around 170 square metres of floorspace. In the basement and ground floor extension, 100-mm and 80-mm PAVATEX wood fibre insulation boards were affixed on top of the existing concrete blocks. 60-mm PAVATEX-DIFFUTHERM boards provided the final layer. This optimised insulating element can be plastered, thus providing an excellent basis for the white exterior rendering. Under the wooden facade on the ground floor, 24-cm thick PAVATHERM wood fibre insulation boards protect the inhabitants from cold, heat and noise. The exterior wall now boasts a U-value of 0.14 W/m2 K, thus satisfying the stringent energy efficiency requirements. Around 150 square metres of the roof were insulated using PAVATEX products. 200-mm thick PAVAFLEX was used between the rafters. This skin-friendly insulating material is easily cut to size using simple cutting tools. 20-cm thick PAVATHERM was affixed under the copper roof beneath the water-repellent and windproof ISOLAIR sarking boards which still permit vapour diffusion. This energy-efficient restoration has given the roof a U-value of 0.13 W/m2 K. The wood fibre insulation boards were worked by Auer Holzbau GmbH & Co KG, the company also responsible for installing the rhomboid cladding. Based in Abtenau and founded in 1971, this family firm specialises in projects involving renewable raw materials. Managing director Georg Auer uses only PAVATEX wood fibre insulating materials, insisting that: “We have been using PAVATEX products for over ten years now and are highly impressed by their quality.”

A pleasant living climate all year round

Passive house-compatible components such as energy-optimised windows were favoured in the construction project. The PAVATEX wood fibre insulating materials are perfectly in keeping with the construction of the house. Whether used under the roof, with the rhomboid cladding or as a baseboard in rendered walls, they lower heating energy consumption and provide a pleasant living climate all year round. So Walter Scheicher is quite correct in stating proudly that he has created a “dream villa” for his parents.
