BSP ECO BRACKET system is designed for fixing lighter cladding panels and resist lower loads on external and internal walls. System consists of BSP KW EB aluminium brackets (alternatively BSP KW1 or BSP KW1 PAS passive brackets), aluminium L-profiles (BSP KWR4, KWR7, KWR10 and KWR11) and T-profiles (BSP KWR3 and KWR9). All of the ECO BRACKET system elements are made of extruded aluminium alloy EN AW 6060 T66 or EN AW 6063 T6.

BSP KW EB brackets are 2 to 3 mm thick. They come in single length which is 170 mm. 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 (1,5 mm wide) 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 KWR3 and KWR9 are T-profiles used at the joints of two neighbouring cladding panels. BSP KWR4, KWR7, KWR10 and KWR11 are L-profiles used as a support behind the cladding panel (usually in the middle). Profiles are selected for each project based on static calculations and design, mostly due to different sizes and outreaches as well as loads they need to resist. Thickness of the profiles has been reduced to 1,75-2,0 mm due to very low forces that they need to resist. Grooved surface of the front part of profiles maximises the connection area for adhesives. 4,8×19 A2 self-drilling screws are used to connect profiles with brackets.

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 ECO BRACKET system 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.
