Collaborating for success
A floating cement floor was placed on the wooden floor to acoustically insulate the homes. Using the Rockzero building system, based on ROCKWOOL’s stone wool, the apartments achieved exceptionally high insulation values – almost at passive level with an RC value of 6 for the façade and an RC value of 7 for the roof. The building system ensured an optimally insulated and fireproof construction, with no cold bridges. The building plan included the installation of approximately 240 solar panels on the flat roof, to supply tap water, warmed by nature, in each of the homes.
It wasn’t the first time that RTR Vastgoed collaborated with Adema Architects. Bernd Bove, project manager at Adema Architects, particularly enjoyed working on this transformation challenge, and explained that the
entire area – formerly very industrial – has undergone thorough change to become a residential zone.
“The building initially had an industrial look that has been completely transformed to become charming homes,” sat Bove. “This pilot from RTR Vastgoed was the last to be rebuilt in this area. In this eight-meterhigh building, split-level homes have been built to create a spacious living quarter that is accessed through a cosy communal courtyard. The floor and part of the façades of the old shed have remained intact, in which the steel construction has been adapted to accommodate a wooden floor and the Rockzero building system.”
Stephen Muller, key account manager at ROCKWOOL, regularly visited the project throughout the construction period.
“For us, this transformation was extremely interesting, because it was the first time we’d used the Rockzerobuilding system within an existing building. RTR Vastgoed chose our building system to be able to apply a lightweight, fireproof façade with façade cladding, which could be built quickly and flexibly on and against an existing building,” explained Muller.
The Rockzero building system contains columns of stone wool, which have a strong structural loadbearing capacity. The building system is light, flexible, non-flammable and insulates well, due to the fact that it is based on ROCKWOOL’s stone wool.
“As a result, the system is suitable for any type of façade and façade finish,” continues Muller. “In this project, the building contains different types of façade finishes that demonstrate that flexibility, such as existing and new masonry and façade cladding. The system is modular, arrives to the site and can be assembled directly.”
The success of the project at Sneek was the direct result of positive team work from RTR Vastgoed, Adema Architects and ROCKWOOL’s technical solutions centre. By using the Rockzero building system, they could rapidly development safe and comfortable homes for
local people with special needs.
