X-Fix stimulates the growth of prefabricated house manufacturer Multicomfort!
The Multicomfort company has been a manufacturer of prefabricated timber frame houses for over a dozen years and for some time now the Polish company has also been building prefabricated houses made of cross-laminated timber. Since the beginning of 2023, Multicomfort has been using X-fix as the main fastener and key component for the prefabricated cross-laminated timber house kits that are exported from near Katowice to all of Europe. The factory in Bytom, which only opened in 2023, produces 80% of walls and ceiling elements for export using a Hundegger Robotdrive and cross-laminated timber in the standard 1.2 m format as well as X-fix C connectors with almost no waste. The company works in a B2B model and its offices can be found in Berlin, Zurich, Amsterdam, Paris, Vienna and Stockholm, among others. For construction sites in the surrounding area, the wall elements are assembled from 1.2 m wide CLT elements and X-fix in the factory and transported to the construction sites. If transporting the entire walls is too far or too expensive, Multicomfort supplies an ideally designed CLT wall and ceiling kit that is assembled by assembly professionals on the construction site using X-fix. “We are currently working on a project with 111 social housing units for the city of Eindhoven/NL, which meets higher ecological parameters than ever before! X-fix is an important part of this.” – says Bartosz Pawliczek, the owner of Multicomfort.

“Das Bärahus” Feldkirch / Austria February 2022: Rhomberg erects a seven-story wooden office building with X-fix
As a timber construction specialist and pioneer, Rhomberg Bau from Bregenz/Austria has now made a name for itself far beyond the borders of Vorarlberg. And this name is now enriched by another facet: At the Bärenkreuzung in Feldkirch, construction of the first all-wood office building from a new wood product range from Rhomberg began: the “office ZERO”. “We can simply show what wood can really do with seven floors with a quality that is otherwise difficult to achieve when building in the traditional way. That’s why I’m pleased that we now have the opportunity to present a new project and a new building type here,” said Hubert Rhomberg, Managing Director of Rhomberg Bau. According to Rhomberg, this building type should be scaled up in the future and used in other projects. 1000 # X-fix C 90 and X-fix C 45 connect the 750 m3 of wood of the “Bärahus”. Construction time 14 months. (Pictures: Rhomberg Bau GmbH)
Oslo/Norway spring 2022: X-fix is a a key component in an 3000 sqm Office building in natural materials designed by Oslotre.
Straye Trebygg AS is building this visionary dismantled and reusable building set with 600 # X-fix C 90. The CLT and the X-fix milling comes from Splitkon / Amot Norway. “HasleTre is a 3000 sqm Office building in natural materials. It is planned as a wooden construction from the first sketch. The façade will consist of chipboard cladding and the idea is that the façade will change expression according to the seasons. Parts of the façade are covered with green plants that work in the Nordic climate, and we have planned a spectacular roof garden which is both a biotope for cultivation and a nice place to stay. The construction consists of wood from the inside to the outside and is planned as a dismantled and reusable building set.” (https://www.oslotre.no/project/hasle-tre/) OsloTre is Consultant agency for architecture, specializing in timber constructions based in Oslo/Norway.
Pirmin Jung builds “House of Wood” with X-fix.
A service and residential building made of wood is being built in Sursee/Switzerland as a showpiece for digital construction with wood. The “House of Wood” will be realized in a future-oriented, energy-efficient timber system construction method and will be realized using the BIM method (Building Information Modeling). For Pirmin Jung, X-fix plays a decisive role in wood connection technology and is used connecting
- ceiling to ceiling
- wall to wall
- beams and pillars to CLT walls
- and (new!) the connection between ceiling and wall. Again a new variant how the engineers from Pirmin Jung use X-fix.

“Crocodile” Winterthur client Implenia / CH is highly satisfied with Hasslacher ceiling systems combined with X-fix, a report from the construction site: Site manager Adrian Ulrich of the company Implenia / CH is thrilled with X-fix and the Hasslacher Norica Timber ceiling elements. “We save more than 30% of the laying time for the floors,” says Adrian Ulrich. “In addition, the X-fix ceiling connection system is qualitatively better, because X-fix automatically closes the gap between the visible ceiling elements.” Ulrich is also satisfied with the static properties of X-fix C. “An X-fix C connector can take 28 kN of shear and tensile load and is therefore more cost-effective compared to steel screws and steel sheet plates that would be necessary to absorb the enormous shear forces of the building in the storey ceilings. “
