BRITISH AND EUROPEAN STANDARDS All membranes comply with BS EN 13707: 2004 Reinforced Bitumen Membrane Sheets for Roof Waterproofing and the cap sheets achieve the highest rating of S5, P5 in BS8747: 2007, the UK guide to selection and use of reinforced bitumen membranes. bauder. ie16 BAUDER TOTAL ROOF SYSTEM FIRE RATING EXT. F. AA rating awarded to the K5K cap sheet for zero spread of flame and no fire penetration. Tested to BS 476 Part 3 ( ENV 1187: 2002) External Fire Exposure to Roofs. The K5K cap sheet incorporates expandable graphite fire retardant so that in the event of external fire on the finished roof, a ' crust' forms on the surface to prevent the spread of fire.

17 bauder. co. uk Bauder Total Roof System This is our premier bituminous system, in terms of both quality and technology. It is robust and durable enough to withstand foot traffic along with most permanently sited plant and is specified in applications where outstanding longevity is required. It can be used in both warm, inverted and cold roof designs on all normal deck constructions and can be used to overlay certain types of existing roof materials. Tapered insulation can be incorporated to provide falls if required. There are different options available to suit all types of roof project: BTRS This is our long- standing torch- applied system with a trusted reputation. It utilises robust SBS modified bitumen membranes of the highest quality. The system is extremely adaptable and features a heavy duty cap sheet. BTRS DUO This option features our patented ' DUO' technology and combines a torch- bonded cap sheet with self- adhesive technology in the underlayer and vapour barrier to provide securely welded laps whilst reducing installation time. The need for a bitumen pot is eliminated and the amount of naked flame required to install the membranes is greatly reduced.
