Rockzero by ROCKWOOL offers housing associations and real estate developers a circular prefabricated building system for a sustainable future. The basis of our building system is ROCKWOOL stone wool. The strength of our prefabricated building system lies in its simplicity. By prefabricating the facades and roofs the construction process can be speeded up considerably, mistakes can be avoided and risks remain low. What is unique about Rockzero's building system? The system exceeds the building regulations requirements far in terms of energy saving, acoustics and fire safety. For example, with a maximum insulation value of Rc9, Rockzero is a 'hero' when it comes to reducing energy demand in the Netherlands. As a result, a Rockzero house performs much better than a traditionally built house. Thanks to the high insulation value, much less energy needs to be consumed during its lifetime and the house becomes much more controllable for the residents, which of course results in more comfort such as lower energy costs.
