Rockwool Rockshell

RockShell is a new system in Rockwool’s portfolio which integrates the unique combination of the four-in-one benefits of Rockwool stonewool – fire resistance, superior acoustics, durability and sustainability – into a modular and energy efficient external load bearing wall. Passivhaus certified, the system achieves a typical U-Value of 0.143W/m2K, making it an ideal specification for projects targeting superior thermal performance or higher levels of the Code for Sustainable Homes. A patented modular system with few components, RockShell is delivered to site in ‘kit form’ according to the specified building design. Constructed of I-shaped steel profiles encompassed in Rockwool insulation and an OSB lining on the inside, RockShell is quick and easy to install and requires no specialist equipment. By simplifying installation and manufacturing the system to an exact specification, RockShell offers increased air tightness and minimised thermal bridges, as compared with traditional building methods. This is achieved by the interface detail of the components and reducing the risk of installation error on-site.
