Siderise BB-FB Balcony Bracket Fireboard

Siderise BB Balcony Bracket provides a rapid solution for continuing compartmentation of cavity barriers and fire stops where interfacing with a balcony bracket in the cavity when abutted either side by Siderise Cavity Barriers and Fire Stops such as:

• Siderise EW– Cavity Barriers and Firestops for use in external masonry wall build-ups
   
• Siderise RH/RV – Cavity Barriers for use in ventilated facade build-ups
   

Siderise BB-FB has been tested in conjunction with a firestop fitted under compression to EN 1366-4:2006+A1: 2010 (WF 426636/R) and achieved over 2 hours of fire resistance – 120 minutes Integrity / Insulation.
 
This product represents 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-FB should be fitted tightly around the baseplate and requires 50mm (2 x layers of 25mm) to the bottom and to either side of the baseplate, and a minimum of 15mm to the top.

Siderise BB-FB comprises of high-density stone wool insulation, the material is faced with a reinforced aluminium foil.
Siderise BB-FB balcony bracket kit is supplied in sheet form (2000x1180mm for 25mm sheets and 1200x1000mm for 15mm sheets). The product is easily cut on site to suit the site measured void size and geometry of the balcony bracket. This methodology provides the greatest level of tolerance. Alternatively, the product can be supplied in kit form to provided measurements on request.  

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 unless the BB-FB is protected from moisture via other means (e.g. cavity tray). DPC to be sourced separately.

Siderise BB-FB is manufactured from non-combustible stone wool faced with reinforced aluminium foil.
Siderise BB-FB has been tested generally in accordance with EN  1366-4:2006+A1: 2010 and achieved 120 minutes Integrity and 120 minutes Insulation (WarringtonFire Test Report No. 426636/R).

Please see Standard Details for further information on the configuration of BB-FB.
