BSP KCS hanging system is used for visible mechanical fixing of glass panels on internal and external walls in ventilated facade technology. System consists of BSP KW1 brackets (alternatively BSP KW1 PAS brackets), BSP KCT and BSP KCL aluminium profiles and BSP KC3 and BSP KC4 hanging elements. All elements of BSP KCS system are made of extruded aluminium alloy EN AW 6060 T66 or EN AW 6063 T6.

BSP KW1 brackets are 4 mm thick. Their length (outreach) depends on cladding panels outreach and they are always chosen based on design and clients request. The size of a bracket depends on its type. Fixed brackets (load bearing ones) come in 150 and 120 mm versions, sliding ones (carrying only horizontal loads) come in 90 and 60 mm versions. There is additional aluminium piece on the side of the bracket that creates kind of a pocket that is used for fixing profiles and enables cladding leveling. All of the slots in the brackets were designed to ensure that aluminium expansion is possible. Brackets are fixed to buildings structure with anchors that are chosen based on static calculations. Pads/washers should be used together with the brackets to separate them from the wall or structure they are fixed to in order to avoid corrosion and decrease overall thermal conductivity. Recommended BSP pads are made of HDPE plastic material but alternatively PCV or EPDM ones can be used. BSP KW1 aluminium brackets are covered by the Technical Approval no. AT-15-9325/2014. They also have positive opinion of the Building Research Institute (ITB) regarding §225 of the Regulation of the Minister of Infrastructure regarding technical conditions that should be met by buildings and their location.

BSP KCT is T-profile used behind the joint of two glass panels. BSP KCL is L-shaped profile used to support glass panels and installed behind them. Both profiles have special sockets for attaching gaskets and rails where hanging elements fit. Rails are additional safeguard for pulling the hanging elements from the profile. KCT and KCL are 1,8 mm thick and have 72 mm long side that guarantees high stiffness and enables large spacing of brackets. 4,8×19 A2 self-drilling screws are used to fix the profiles.

BSP KC3 is single end hanging element used on the bottom and at the top of the glass facade. BSP KC4 is double middle hanging element used to fasten glass panels at their joints. Both of them have grove on the edge to fit into KCL and KCT profiles. They also have sockets for attaching gaskets that push the glass panels and stabilize them. Additional seal is glued to the hanging element to prevent direct contact of glass with aluminium. Hanging elements are 34 mm wide. Visible part of them can be powder coated. Hanging elements are fixed using stainless steel screws or self-driling screws. The exact type of screw should be selected based on static calculations.

All elements of BSP substructure system have B durability class in accordance with PN-EN 1999-1-1:2011 and may be used without any additional anti-corrosion treatment in environments of class C1, C2 and C3 according to PN-EN ISO 12944-2:2001. If additional protective layer is applied – anodizing – they can be used in environment of class C4. All elements of the system are also classified as A1 class in the scope of reaction to fire according to PN-EN 13501-1+A1:2010 based on the decision of the European Commission No. 96/603/EC,  2000/605/EC and 2003/424/WE.

BSP systems should be installed in accordance with the workshop design prepared by engineers and designers with sufficient knowledge in the field of construction and building. The layout of the structure and the spacing between the elements (strength and resistance of the entire system) should be confirmed by the static calculations prepared by the engineer with qualifications in the filed of construction and building.
