Occupying a prominent position on the Kingsway, The Curve development is a portfolio of 27 apartments. The key requirement for Cube Homes was to offer residents high quality, low carbon, affordable and sustainable apartments.
After extensive planning, K Systems specified a direct fix system with mineral wool insulation and a silicone render finish. Our Direct Fix system for steel frame structures is KIWA BDA certified and provided the ideal solution for these newly constructed mid-rise apartments.
Our team designed a façade solution that delivered modern, thermally efficient and aesthetically pleasing homes, meeting the client’s requirements.
Due to the number of fixings and the curvature of the property, this was a technical project which required bespoke detailing.
In collaboration with Bowker Sadler Architects and our approved installer Profac, we designed a comprehensive specification and were on-site when required, offering Profac technical and installation support throughout the build.
The Direct Fix system specified is a cost-efficient solution for steel frame structures, with fewer components for a simpler and faster install. Direct Fix generates exceptional insulation and with a silicone render finish provides high levels of fire rating (A2,s1-d0), allowing Cube Homes to deliver safe and thermally efficient homes.
Technical Project Details
The EWI needed to be line and level with the ground floor brickwork. To achieve this specific requirement, 300mm mineral wool (which is deeper than available mineral wool) was specified for the project. This meant 110mm and 190mm boards were combined to achieve the required 300mm.
This thicker mineral wool meant that the curved elevation on the building was difficult to achieve. The insulation was facetted around the curve and carefully installed by Profac to create a seamless façade. The 300mm mineral wool resulted in a low U-value of circa 0.10 W/m²K, meaning heating costs for the apartments will be minimal and carbon usage will be reduced to a minimum standard.
For the finish, silicone render (TC 15) was specified to create a striking curved elevation. Silicone TC incorporates the benefits of silicone technology to provide a water repellent finish with a fresh and modern appearance. The silicone allows water vapour to pass freely through the render whilst allowing the finish to remain weather resistant, making it the ideal solution for a low maintenance, long-term finish.
