SOYO Leeds, Quarry Hill

OVERVIEW

SOYO Leeds is a £300 million mixed use scheme that creates a new neighbourhood adjacent to the city’s cultural quarter.


Designed by DLG Architects for Caddick Construction and Moda Living, SOYO Leeds will comprise residential and student accommodation, a hotel, restaurants, bars and offices. And at the heart of this new cultural centre is 10,000m2 of Knauf Insulation Rocksilk® RainScreen Slab.


During the construction of the scheme’s 515 hotel-style rental apartments, rainscreen contractor Axis Envelope Solutions needed to source suitable, compliant insulation. So, it consulted Knauf Insulation, the UK’s only manufacturer of Glass and Rock Mineral Wool insulation, about which solutions would meet the required thermal and fire performance specification.


Knauf Insulation’s Specification Team reviewed the architect’s drawings which included a build-up featuring a steel top hat. The company’s Technical Support Team then undertook 3D U-value calculations completed in line with BS EN 10211 to ensure the finished building’s performance matched the initial design.


Because 3D U-value calculations are done in-house, the team were able to turn around the complex calculations in the time frame required.


Once the calculations had been performed, Knauf Insulation recommended 180mm Rocksilk® RainScreen Slab as the optimal solution to meet the thermal requirements of the build.


As well as exceptional thermal performance, Rocksilk® RainScreen Slab is highly sound absorbent with excellent sound reduction capabilities. It is non-combustible with the best possible Euroclass A1 reaction to fire classification so will not contribute to the development or spread of fire should it occur. This means it meets the requirements of building regulations in England and Wales banning the use of combustible materials on all buildings over 18m. In addition, Rocksilk® RainScreen Slab is British Board of Agrément (BBA) certified for use in high rise buildings and for the broadest range of thicknesses and build-ups of any rainscreen solution on the market.


Rocksilk® RainScreen Slab is manufactured with ECOSE® Technology, Knauf Insulation's unique bio-based binder that contains no added formaldehyde or phenol. It is made from natural raw materials that are rapidly renewable and is 70% less energy-intensive to manufacture than traditional binders, so it is more environmentally friendly.


Products made with ECOSE® Technology are soft to touch and easy to handle. They generate low levels of dust and VOCs, and have been awarded the Eurofins Gold Certificate for Indoor Air Comfort.


Rocksilk® RainScreen Slab has been designed for ease of use. It is robust which makes it is easy to manoeuvre into place and it can be installed either way round without compromising performance. The Mineral Wool knits together and adapts to imperfections in the substrate, preventing air gaps that compromise thermal, fire and acoustic performance.


Thanks to the responsiveness of Knauf Insulation’s Specification and Technical Support Teams, Axis Envelope Solutions was able to keep to the tight schedule required. As a result, the new tenants of the luxury apartments at SOYO Leeds will be able to enjoy homes built to provide the highest level of thermal, fire safety and acoustic performance in the centre of the city’s newest cultural hub.
