Rawlplug on historic walls of the Żup Krakowski Museum in Wieliczka!
Historic architecture, challenging installation conditions and demanding thermal upgrading – the castle complex in Wieliczka is a place where standard solutions simply aren't enough!
The Żup Krakowski Museum in Wieliczka is a national cultural institution whose exhibitions are housed in the historic buildings of a former salt mine. Since 1978, the complex has been listed as a UNESCO World Heritage Site.
Project challenges and investor expectations
The refurbishment involved three buildings forming the museum complex: the Central Castle (housing permanent and temporary exhibitions), the North Castle (with offices, an archive, a library and a café), and the South Castle (with a restaurant, studios and guest rooms).
One of the most critical stages of the work was the thermal modernisation aspect, carried out with full respect for the site's historical character. The project required the installation of 320 mm thick thermal insulation, which called for a carefully selected mechanical fixing system. The investor was looking for a solution that would ensure secure anchoring, aesthetic appearance and long-term performance on a demanding substrate.
Rawlplug solutions on site
Following a detailed on-site assessment, Rawlplug experts recommended the use of R-TFIX-8S – universal screw-in facade fixings offering top performance across all ETICS applications, tested and approved for use in all substrate categories: A, B, C, D and E.
Thanks to its unique anchoring zone design, the R-TFIX-8S can safely transfer high loads, which in turn allows for a reduction in the number of fixings required per square metre. Its fast and easy installation, high plate stiffness and low point thermal transmittance make it an excellent choice for renovating historical buildings, where precise adaptation to the existing structure and minimal interference with original architectural elements are essential.
The fixings were supplied via the 3W distribution network, which also provided other materials needed on site – helping maintain workflow continuity and meet tight project deadlines.
