Siderise BB Balcony Bracket provides a rapid solution to a complex detail and allows continuity of cavity compartmentation when abutted either side by Siderise Cavity Barriers and Fire Stops such as:
Siderise BB has been tested to EN 1363-1:2012 (WF 409690/426636) and achieved over 2 hours of fire performance – 120 minutes Integrity / Insulation (EI 120).
These products represent an ideal combination of qualified performance and practical installation.
Balcony bracket connectors come in a wide range of styles and sizes, therefore project-specific advice for your application should be sought from Technical Services.
The suitability of these products for a given Project Specific Detail depends upon many factors, primarily:
The size and geometry of the balcony connector and its associated base plate, fixing bolts, and thermal break
The size and position of the balcony connector and its associated base plate relative to the thickness of the compartment slab
Clearance around the connector and any potential clashes with surrounding elements
In order to offer feedback on the suitability of these products within the Project Specific Detail, we would require detailed drawings of the connector which should be fully dimensioned and also show the relationship between the connector and the slab/compartment floor assembly (i.e. how much clearance there is to the top/bottom of the floor). Any thermal break material should be shown and the nature of the material identified.
Please provide architectural drawings in vertical section, horizontal section, and elevation. These should be dimensioned and indicate the proposed positioning of cavity barriers or firestops and their required fire resistance.
Siderise BB is available in two primary forms with the following minimum clearances around the baseplate specified:
Siderise BB-CB comprises a low resin content stonewool insulation core which is pre-compressed internally to form a resilient strip. The material is faced with a reinforced aluminium foil which is an effective smoke barrier.
Siderise BB-CB balcony bracket kit comprises of 4 pre-cut interlocking sections that encapsulate the balcony bracket connection.
Siderise BB Cavity Barrier solutions should be installed in accordance with PD 6697:2019 - 'Recommendations for the design of masonry structures to BS EN 1996-1-1 and BS EN 1996-2' when used in conjunction with Siderise EW in external masonry wall build-ups:
Must be installed with a DPC extending a minimum of 25mm into the cavity either side of where the product contacts the brickwork. DPC to be sourced separately.
Siderise BB-CB is manufactured from non-combustible stonewool that is rated A1 to EN 13501-1 as a standalone material and is covered in a reinforced aluminium foil.

|SIDERISE® BB-CB||120||120||EI 120|
|SIDERISE® BB-FB||120||120||EI 120|
Thermal conductivity :
Siderise BB-CB: λ10 = 0.038 W/m.K (tested foil to foil)
Siderise BB-FB: λ10= 0.042 W/m.K (tested foil to foil)
When used in conjunction with an external masonry wall, it must be damp-proofed in accordance with PD6697:2019 - 'Recommendations for the design of masonry structures to BS EN 1996-1-1 and BS EN 1996-2'.
Table 2: Product Properties
|Reaction to Fire||BB-CB Classification to EN 13501-1 : 'A2' |
BB-FB Classification to EN 13501-1 : ‘A1’
|Resistance to Fire||Classification to EN 13501-2 : Please see Table 1 : EI 120|
|Thermal Conductivity||BB-CB : λ10 = 0.038 W/m.K (tested foil to foil) |
BB-FB : λ10 = 0.042 W/m.K (tested foil to foil)
|Chemical||The base stone wool is chemically inert. An aqueous extract of the rock wool is neutral (pH7) or slightly alkaline. Resistant to most acids and weak alkaline solutions.|
|Biological||Vermin and rot proof and does not encourage the growth of fungi, moulds or bacteria.|
|Effect of water||Non-hygroscopic. Unaffected by humid atmosphere. Must be suitably damp proofed in accordance with codes of practice for masonry constructions.|
|Compatibility||Compatible with all normal building materials.|
|Maintenance||No maintenance required unless disturbed.|
|Handling||Easy to handle but should be treated with due care to ensure material integrity and shape are maintained.|
|Storage||Store in dry conditions.|
Siderise offers a number of ancillary products to complement the BB-CB/FB, these include:
Spiral Fixings which are required as part of the BB-CB/FB kit and must be installed as per the Installation Instructions.
Aluminium Jointing Tape must be used at all joints and intersections:
