Fire Barrier CP25WB+ Sealant

Transcription

1 Fire Barrier CP25WB+ Sealant Product Data Sheet Supersedes: New Version Product Description & Intended Use 3M Fire Barrier CP 25WB+ Sealant is a high-performance, readyto-use, gun-grade, latex-based, intumescent sealant that dries to form a monolithic fire stop seal which also acts as a barrier to airborne sound transmission. 3M Fire Barrier CP 25WB+ Sealant is used to reinstate the fire resistance performance of flexible and rigid wall constructions where they are penetrated by various cables and metallic pipes. In addition, the unique intumescent property of this material allows 3M Fire Barrier CP25WB+ Sealant to expand and help maintain a firestop penetration seal for integrity (E) against the passage of flame and insulation (I) against the rise of temperature as service penetrations are exposed to fire. Key Features European Technical Approval - ETA - 09/0326 R1 tested in accordance to ETAG No 026: Part 2 - Penetration Seal, Edition Test to EN :2004 Fire Resistance for service installations - Part 3: Penetration seals Fire Classification in accordance to EN :2003 Typically used in electrical and plumbing applications to fire stop openings created by the following penetrations in fire-rated flexible and rigid walls: metallic pipe, power and communication cable penetrations. Water Base Intumescent with a strong expansion Helps to minimize sound transfer Helps control the spread of fire, smoke and noxious gasses before, during and after exposure to a fire when installed in accordance with a tested service penetration assembly system. Applied with conventional caulking equipment and putty knife Sag-resistant to prevent material from slumping Paintable to match surrounding aesthetic Water clean up Excellent adhesion Page 1 of 7

3 Performance Characteristics (continued) Fire Performance Fire Resistance Standard EN : 2004 Fire Classification Up to E 240 & EI Reaction to Fire Supporting Construction E classification Flexible Walls Thickness Min. 150 mm 1 Note: 1 The wall must have a minimum thickness of 150 mm and comprise timber or steel studs lined on both faces with minimum 2 layers of 15 mm thick, Type F Gypsum boards according to EN 520. In timber stud walls, no parts of the penetration shall be closer than 100 mm to a stud, the cavity must be closed between the penetration seal and the stud and minimum 100 mm of insulation of class A1 or A2 according to EN , is provided within the cavity between the penetration seal and the stud. Rigid Walls Thickness Min. 150 mm 2 Note: 2 The wall must have a minimum thickness of 150 mm and comprise concrete, aerated concrete or masonry, with a minimum density of 650 kg/m3. Specific considerations for supporting construction The supporting construction must be classified in accordance with EN for the required fire resistance period. Aperture Details Aperture Sizes Circular: up to 152 mm Aperture Separation Min. 200 mm Service Penetration Area Max. 60% of the of the aperture area including insulation Service Support Specific considerations for penetrations seals: Shall be supported at 220 mm and 410 mm from both faces of the wall The seals may only be penetrated by the services described in ETA-09/0326 Revision 1 or in this Technical Data Sheet; other parts or support constructions must not penetrate the seal. The service support construction must be fixed to the building element containing the penetration seal or a suitable adjacent building element, on both sides (walls) and upper face (floors) of the penetration in such a manner that in the case of fire, no additional load is imposed on the seal. Furthermore it is assumed that this support is maintained for the required period of fire resistance. Page 3 of 7

Pipes must be perpendicular to the seal surface Compressed air systems must be switched off by other means in case of fire The approval does not address any risks associated with leakage of dangerous liquids or gases caused by failure of the pipe(s) in case of fire Classifications for pipes relate to (pipe end capped inside & uncapped outside the furnace) refer to national regulations The function of the pipe seal in case of pneumatic dispatch systems, pressurised air systems etc. is guaranteed only when the systems are shut off in case of fire. The assessment does not cover the avoidance of destruction of the seal or of the abutting building element(s) by forces caused by temperature changes in case of fire. This has to be considered when designing the piping system. The durability assessment does not take account of the possible effect of substances permeating through the pipe on the penetration seal. Specific considerations for cables penetration seals: Cables maybe singular or in bundle. Min. separation between adjacent services shall be 10 mm. Cables to be positioned a min. of 30 mm from the edge of seal. For tied cable bundles the space between cables shall be sealed. The cables type s covers currently and commonly used in building practice in Europe subject to the cable size, except tied bundles, waveguides and non-sheathed cables (wires). Optical fibre cables are covered. Tied bundles with diameter of less than or equal to the bundle tested made from cables of a diameter not greater than 21 mm are valid. See EN : 2004 for cables field of direct application details. Page 4 of 7
