Pipe fixing system and collar
The new passive fire protection system
Valsir Collarwings is the new range of fire stop collars produced in compliance with the most recent standards and suitable for installation on plastic waste and drainage pipes. The Collarwings fire stop collars are made of steel and painted with polyester powder fitted with special intumescent inserts which, in the event of fire, expand and squeeze the pipe thus preventing the passage of flames, combustion gas and vapours and acting as a thermal insulation.
The collars can be installed either in a vertical wall or in the slab and they have a fire resistance class of EI240 in compliance with European Standard EN 1366-3.
