Thermally Insulated Balcony Connectors High integrity structural solutions to minimise cold bridging and its associated issues Energy efficiency is becoming increasingly important in today’s sustainable building designs and the thermal performance of the building envelope is a key design consideration. At the same time, architects are looking to create stylish, aesthetically appealing, mixed-use developments that combine high density occupancy with accessible outdoor space. Balconies often provide the answer, but as they typically pass through the building envelope, the fixing detail...

Thermally Insulated Balcony Connectors Ancon Isolan Ancon Isotec For Concrete-to-Concrete Applications Isolan is a simple, cost-effective thermal break system for most concrete-to-concrete applications. It provides continuity to both the wall insulation and the slab reinforcement. Standard systems, comprising rigid CFC-free polystyrene insulation and stainless steel shear reinforcement, suit a minimum slab depth of 160mm. The Isolan system uses conventional reinforcing bars to provide the tension and compression reinforcement. When compared to systems where this reinforcement is an integral...

Ancon STC For Steel-to-Concrete Applications The STC system is used for anchoring steel balconies to concrete floor slabs and has been proven through thermal modelling to reduce heat loss when compared to direct connections. The two part assembly, comprising a cast-in anchorage and a post-fixed bracket with thermal pad located at the interface, allows for phased construction, reducing the risk of the units being damaged during the construction process. Manufactured to order, the bracket depth can be designed to suit the exact requirements of the application and avoid conflicts with the...

Thermally Insulated Balcony Connectors Ancon Isolan System Benefits Cost-effective concrete-to-concrete connector Uses conventional rebars to provide tension and compression Accommodates all structural loads Modular design allows for special configurations Available in depths to suit most common slab thicknesses Fire protection available Standard Isolan systems, comprising rigid CFC-free polystyrene insulation and stainless steel shear reinforcement, suit most depths of cantilever and simply supported balconies. The various systems allow the transfer of all loads in structural concrete i.e....

System Components ISO-Element The ISO-Element is 60mm thick, CFC-free, rigid white polystyrene insulation in a standard length of 750mm. It is available in five heights (160, 180, 200, 220 and 240mm) to suit different depths of balcony. Rail A high density polyethylene rail is located on the top edge of the ISO-Element to protect the insulation. Tension/Compression Reinforcement (Not Supplied as Standard) Reinforcement used for tension and compression bars to be grade B500B to BS4449: 2005. These can be sourced independently or supplied by Ancon. Corrosion Resistance The Ancon Isolan system...

Specification Guidance Design Information The graphs on pages 11 to 13 are used to select the most appropriate Isolan element, and the diameters of the shear, tension and compression reinforcement. Example calculations are provided on the following page. Consideration should be given to horizontal forces on parapets and local concentrated load checks, these are not included in the examples. The graphs provide the design resistance (ultimate limit state) values for the shear VRd and moment MRd. The Isolan element design is based on normal structural calculations. The calculations are based...

Thermally Insulated Balcony Connectors Design Considerations Corner Details Where the diameter of either the tensile or compression reinforcement is above 12mm special consideration should be given at corners to avoid a reinforcement clash. 20mm thick polystyrene make-up strips are typically detailed on the Isolan units to be installed locally at the corner. The corner units should be specified shorter in height than those slab. The filler pieces are the adjacent corner units. This is a simple and cost-effective way of ensuring the bars fall in a different horizontal plane. When using 10mm...

Misalignment of Compression Bars Ancon Isolan components are fast and simple to install. These steps are provided as guidance and should be followed in conjunction with the site engineer’s instructions and structural engineer’s reinforcement details. Compression reinforcement (other bars omitted for clarity) Any polystyrene which is damaged must be replaced or alternatively, where possible, patched with polyurethane foam to maintain the insulation properties. Step 1 The Isolan system should always be orientated so the stainless steel shear reinforcing bars are at the bottom of the slab on...
