The energy challenge The race for energy-efficient solutions has begun The UK has a big challenge The UK has a big challenge. The Climate Change Act of 2008 set the target to reduce greenhouse gas emissions by 80% from 1990 levels by 2050. One of the key methods of achieving this goal is to improve the energy efficiency of our buildings. In Europe and the US, our buildings account for up to 40% of our total energy consumption. By improving the efficiency of our buildings through better materials and design, there is huge potential to reduce CO2 output. A poorly insulated house can use up to...

Insulation is a key climate technology Heating and cooling are the main sources of energy consumption in buildings. Together they account for more than two thirds of a building’s energy usage. At present most of this energy is wasted due to inadequate insulation. During its lifetime, a typical Rockwool insulation product will save 100 times the amount of energy and CO2 emissions that it takes to produce, distribute and recycle it. This makes Rockwool insulation one of the most effective solutions that can be utilised to help reduce climate change. Low energy houses do not need to...

Tomorrow’s energy efficiency delivered today Minimal energy loss with optimal construction methods What is the RockShell wall system? RockShell is an innovative system for constructing the load bearing walls of low-rise buildings. The RockShell wall system is a patented modular system, which meets future energy efficiency requirements, today. The RockShell wall system combines the requirements for sustainable lightweight constructions with optimal energy performance, efficient installation processes, technical support and end user benefits. In other words: The RockShell wall system is the...

Functional architecture Open spaces. Life in the open. A house design where nature meets functional architecture. Signalises an active lifestyle. The combination of plaster, large windows areas and wooden elements on the facade is synonymous with exclusivity. Timeless living An elegant one storey building framing the privacy of the life of the modern family. A timeless house design for the style conscious individual. The simple expression of this courtyard garden house can be used for multiunit houses as well. U-values: Total wall thickness 364.5 mm Total insulation thickness 295 mm *) The...

A simple and straight forward construction method 8 Principles of the RockShell system RockShell is a modular wall system designed for ease of installation, whilst maximising safety throughout the build process. This is achieved without compromising on the end user benets of energy performance, sustainability, indoor climate or building quality.

The first house built using RockShell was in Flensburg, Germany. It was based on a standard design. This house type was utilised to show how easy it was to integrate the RockShell wall system into an existing design and also to prove that it is possible to build a standard house with excellent energy performance and low installation costs. The low-energy house was a KfW 70 energy-efficient house. Offering a 30% improvement in energy efficiency over traditional methods, in line with market requirements. 5 The exterior face of the wall 6 The interior face of the wall 8 Connecting to roof and...

Bottom profiles are used to fix the wall to the foundation and brackets are used to fix the RockShell modules. 4 The unique slits on all four sides of the wool elements make them fit perfectly into the flanges of the steel profiles. A further profile is mounted on top of the RockShell modules and fastened to the -profiles. Finally a laminated veneer...

The exterior face of the wall Intermediate floor Laminated ”nailers” are mounted onto the external face of the RockShell wall. The ”nailers” serve three basic functions. They cover and tighten joints between the RockShell wool elements, establish a ventilated cavity and create a secure mounting for the chosen external finish. The interior face of the wall The intermediate floor is mounted to the RockShell wall system on the interior face of the OSB by securing into the laminated timber bearer and steel -profiles located behind the OSB boards. 8 OSB boards are mounted directly onto the...
