2 I. SPECIFIC PARTS OF THE EUROPEAN TECHNICAL ASSESSMENT 1 Technical description of the product 1.1 Definition of the construction product 1. Hilti Firestop Joint Spray CFS-SP SIL is a membrane-forming coating used to form a perimeter seal between rigid floor slabs and curtain walling with mineral wool as backfilling material. In facade constructions the coating is normally only applied on the top side. Very porous joint edges are treated with Hilti Firestop Joint Spray diluted with a suitable solvent, to achieve better adhesion. For details of the seal design depending on orientation, building elements forming the joint/gap or backfilling material and the related classifications see Annex For further details on Hilti Firestop Joint Spray CFS-SP SIL see Annex 2. For a specification of suitable mineral wool as backfilling material see Annex For a description of the installation procedure see Annex Ancillary products 1. Mineral wool backfilling: see Annex 1. 2 Specification of the intended uses of the product in accordance with the applicable European Assessment Document (Hereinafter EAD): EAD Intended use The intended use of Hilti Firestop Joint Spray CFS-SP SIL is to provide fire resistance performance in the area of the perimeter joint between a curtain wall and rigid floor slabs. The specific elements of construction between which Hilti Firestop Joint Spray CFS-SP SIL may be used are as follows: a) Rigid floors: The floor must have a minimum thickness of 150 mm and comprise concrete with a minimum density of 2400 kg/m 3. b) Curtain wall: Curtain walls with steel framing (transoms, mullions), the cavity formed by the spandrel panel and the framing filled with stone wool board or stone wool lamella board of a nominal density of minimum 60 kg/m 3 to form the perimeter joint edge, coated on the upper side with the Joint Spray CFS-SP SIL see figure in Annex 3. The rigid floor must be classified in accordance with EN for the required fire resistance period. The provisions made in this European Technical Assessment are based on an assumed working life of the Hilti Firestop Joint Spray CFS-SP SIL of 10 years, provided that the conditions laid down in the manufacturer s datasheet and instructions for the packaging / transport / storage / installation / use / repair are met. The indications given on the working life cannot be interpreted as a guarantee given by the producer, but are to be regarded only as a means for choosing the right products in relation to the expected economically reasonable working life of the works.
