BSP KW PAS passive brackets have been designed for stricter regulations regarding thermal insulation parameters of exterior partitions. Structural function of the brackets is to transfer the loads from the facade to the building structure. Fixed brackets transfer both vertical and horizontal loads while sliding brackets transfer only horizontal loads. They are fixed with two and one anchor, respectively. Innovative shape and materials used to produce brackets result in a relatively high load capacity and very favorable thermal parameters. Thermal bridges phenomenon is greatly reduced thanks to this solution.

KW1 PAS, KW2 PAS and KW3 PAS passive brackets consist of aluminium elements and a thermal insulation spacer made of epoxy-glass laminate (thermal conductivity coefficient λ=0,36  [W/(m*K)]).  Mechanical properties of the separator have been tested in the Department of Building Materials Engineering at Building Research Institute (ITB). Test results are described in the report no. LZM00-02956/16/Z00NZM. The separator is connected to aluminium elements with stainless steel rivets.

KW4 PAS passive bracket consists of aluminium elements and a plastic chamber spacer with very good thermal insulation parameters. The chambers of the spacer are covered by insulation wool creating non-ventilated air space, which also has a positive effect on thermal insulation. The spacer is clamped in the sockets of aluminium elements and thus connected to them in a permanent manner.

All aluminium elements of KW PAS brackets 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.
