Concrete-to-Concrete Balcony Connectors

Ancon Isolan insulated balcony connectors have been installed on the seven storey Daisy Spring Works development in Sheffield, UK.

The Isolan system provides a thermal break between the external concrete balconies and the internal concrete floor slabs.

In applications such as balcony locations, where concrete slabs pass through the building envelope, a ‘cold bridge’ is created that can result in significant heat loss. Ancon Isolan systems provide continuity to both the slab reinforcement and the thermal insulation of the wall to protect against the effects of cold bridging.

Standard Isolan systems, comprising rigid CFC-free styropor insulation and 1.4462 Duplex stainless steel shear reinforcement, suit most depths of cantilever and simply supported balconies.

Isolan connectors allow the transfer of all loads in structural concrete i.e. moment, shear, compression and tension, and are suitable for straight runs, corners, curved/stepped balconies and precast concrete.

Unlike other balcony connection systems, Isolan uses conventional grade 500B reinforcing bars to provide the tension and compression reinforcement. When compared with systems where this reinforcement is an integral component, the Ancon Isolan system can provide substantial cost savings and simplify specification, scheduling, transportation, handling and installation.

The Isolan system has a typical u-value of 0.3W/m2k.
