Safe and multi-variant R90 mixed installation


BSM®-GuKu®: System-tested fire protection components for versatile use – also as a set

The R90-fire protection system, BSM-GuKu is designed for a whole range of installation tasks with material transition. According to the intended purpose, Missel offers various designs of individual fire protection insulation jackets up to a complete set; prefabricated fittings included. According to the general building approval, numerous installation possibilities can be realized.

Whether the change of material is realized in the ceiling duct, with a side or vertical transition, at the branch or in the downpipe: The fire protection insulation sleeves BSM-GuKu Set, BSM-GuKu FL and individual BSM-GuKu from Missel enable a safe and practical fire protection solution with many different cast plastic pipe transitions.

Numerous general building approval certified mounting possibilities
The general building approval (AbZ Z-19.17-2215) ensures the maximum possible safety in the design and installation with the BSM-GuKu system for all construction parties. Since 1 January 2013 these usability certificates have been mandatory for installations where the metal pipes run through fire resistant building components and are connected to plastic pipes.

Space-saving fire protection solutions in accordance with the general building approval
The general building approval also allows for mounting at a minimal distance with the BSM-R90 for supply and heating pipes from steel, copper, plastics or multi-layer composite. The BSM-GuKu can be mounted at a distance of 10 mm without further smoke-screens.

Continuation of the downpipe with plastic in renovations
The use of Missel BSM-GuKu FL has also been tested according to the general building approval in an important mounting situation in the field of renovation. In bathroom reconstructions, often the cast iron sewage pipe in the ceiling duct is led forward not with the original pipe material but rather with an easily processed plastic pipe. Here the solution developed by Missel for the fire protection enhancement in the area of material transition in the downpipe is appropriate. Mixed installations up to the standard profile of DN 100 at the transition from cast iron down pipes to plastic pipes are admissible.

The complete solution for each individual installation situation
The ceiling duct with the material transition to combustible plastic pipes needs a systemic fire protection solution with several supplementary components. The BSM-GuKu Set for the side transition at the branch and the BSM-GuKu FL for the mixed installation in the downpipe consist of individual fire protection insulation sleeves BSM-GuKu and additional custom-fit prefabricated fittings for different pipe segments.
