Rockwool insulation has been installed throughout London Coliseum's roof terrace and winter garden.
The basic elements of the ruralZED house cost just GBP116,000 and a typical property can be constructed in a month, although the prototype unveiled at Ecobuild was built in just three days.
Dunster continues: "All the materials used in ruralZED house design have been thoroughly tested and carefully selected for their buildability, advanced, multi-functional performance and sustainability credentials.
For example, Rockwool insulation not only provides excellent thermal insulation, it is also extremely sustainable, completely non-combustible and provides very high levels of acoustic protection".
Rockwool Flexi is a stone wool product, which features a natural 'spring' to ensure a flush fit that eliminates air gaps, even with out-of-true walls.
The product flexes with the building structure in order to maintain this tight fit despite shrinkage throughout the life of the building.
In addition, Flexi moulds round any surface irregularities like bolts and fastenings, unlike rigid foam insulations, maximising airtightness levels and the thermal performance of the building structure.
Rockwool Flexi offers a superior 4 in 1 solution: In addition to its excellent thermal properties, Flexi is classed as non-combustible and has excellent acoustic properties and sustainability credentials.
Rockwool stone wool insulation is one of the most environmentally friendly and energy efficient construction products available and meets the highest standards of 'cradle to cradle' sustainability, energy conservation and recyclability.
It is manufactured using igneous volcanic rock, an abundantly-available resource.
Over the lifetime of the building, the energy saved could be 100s of times more than that consumed to manufacture the Rockwool insulation.
Rockwool insulation has a low embodied energy of 16.8MJ/Kg and has zero Ozone Depleting Potential (ODP) and Global Warming Potential (GWP).
Its excellent thermal properties cut energy consumption, reducing the need to burn fossil fuels and therefore helping to minimise harmful emissions of greenhouse gases.
