P|8 Progress ponents of building elements. Construction compo- nents or elements of a building are made of a variety of materials or construction products, and they are often assembly-bonded compound elements. Both building materials and construction elements have to meet the standards with regard to their fire behaviour. Building materials are tested for their fire behaviour and classified. The so-called fire classes are defined in the European Standard EN 13501-1, as noncombustible (A), difficult to ignite (B, C), normal combustibility (D, E), and easily ignited (F). This standard European clas- sification also covers the criteria smoke production, development of droplets and flaming droplets.The as- sessment of the flammability of a construction product is not transferable to the building element, these are classified in the EN 13501-2. The elements are tested and evaluated separately with regard to their flame re- sistance under consideration of the fire class. Fire protection: The role of the adhesive The assembly of building elements that are flame-resi- stant is made possible by using adhesives. Elements like flame-resistant doors, or so-called fire barriers, ser- ve the purpose of protecting the wall openings of fire- resistant or fireproof walls against penetration by fire or smoke. Modern adhesive technology allows to manuf- acture these kinds of doors or ceiling elements which in their appearance are very similar to “normal” products. Apart from the general strength properties of the ma- terial compound, the adhesive itself can contribute to increase the fire protection behaviour of the building elements. Jowat has for instance developed an adhe- sive system which is formulated with specific additives. When this adhesive is used in the assembly of a buil- ding element, it will support the flame-retarding effect. The adhesive in practice Armstrong Building Products GmbH, in its Muenster location, is a specialist for ceiling systems, floor co- verings and insulation materials. Their manufacture of flame-resistant ceiling elements relies on Jowat adhe- sives. These are major functional components of the More than a safe feeling: Buildings with fire protection Industry Wood | Construction | Furniture
