Vertical base BIS Yeti + BUP mat 280x280 mm 67685281

Roof support systems for flat roof installations

The BIS Yeti vertical foot + BUP mat is a key component of the Walraven Yeti 280 modular roof support system, designed for the professional installation of various systems on flat roof surfaces. The system has been specifically developed for air conditioning installations, service pipes, units, technical walkways, and photovoltaic panels.

The modular design of the system allows for flexible adaptation to the specific requirements of each project. The vertical foot provides a stable base for a 41x41 mm RapidStrut rail, which can be rotated a full 360° within the support. This functionality allows for optimal installation layout even in the case of complex pipe and cable arrangements.

Particular attention has been paid to operational safety - the anti-slip insulating mat not only protects the roof surface from damage but also provides additional stability to the entire structure. Before installation, it is recommended that a qualified installer verifies the maximum load-bearing capacity of the roof covering.

Construction and materials

The foot is made of advanced WPC (Wood Plastic Composite) material, which is an innovative composite of plastic and natural wood fibers. The material exhibits high resistance to ultraviolet radiation and chemical agents encountered in the construction environment. UV resistance has been confirmed by the Building Research Institute certificate in accordance with the PN-EN ISO 16474-3:2014-02 standard.

All plastic components are made from 100% recycled material. The WPC composite maintains its mechanical and aesthetic properties through many years of exposure to weather conditions. The material does not corrode like metal counterparts and does not require periodic painting or maintenance characteristic of wooden elements.

Dimensions and acoustic insulation

The element has dimensions of 283 x 283 x 58 mm (total width x total length x total height) with an element height of 10 mm. The total product mass is 0.61 kg, which ensures structural stability while maintaining a reasonable load on the roof structure.

The system has been designed in accordance with strict standards regarding acoustic insulation. The vibration-acoustic insulation meets the requirements of DIN EN ISO 10140-1 and DIN EN ISO 10140-3 standards, resulting in a significant reduction in the transmission of vibrations and noise to the building structure. This is particularly important when installing air conditioning units and other systems that generate vibrations.

The product catalog number is 67685281, which replaces the previous model 67685280 (discontinued). The manufacturer recommends contacting the Walraven Technical Department to perform detailed load calculations for a specific application and to determine the maximum load capacity of a given roof structure.
