The SIG I-House incorporates Celcon Elements from H+H to deliver the speed of offsite construction with the familiarity of a traditional build, building the shell from foundations to roof in just five days, it is claimed.
The system can encompass the inner leaves of external cavity walls, floors, lintel, cavity closers, insulation and roof trusses. With the inclusion of soffit and fascia, the system delivers the internal skin of a property, fully wrapped and ready for follow-on trades.
The system is intended for the construction of domestic houses of up to two storey height, replacing the structure of the inner leaf of external cavity walls, separating walls and internal partitions with storey height Celcon Elements.
The external skin can be brickwork or any other form of masonry.
Installed by the SIG Offsite team, Celcon Elements are craned into place and fixed using H+H element mortar. Timber I-Joist cassette floors are used to maintain the speed of build and roofs are either standard truss construction or the Roofspace I-Roof – panelised roof system. All components are raised into position by crane.
H+H says that Celcon Elements are manufactured from the same material as aircrete blocks and have the same performance, including reduced heat loss at thermal bridges.
