BUILDING RESEARCH &INFORMATION (JANUARY–FEBRUARY 2005) 33(1), 41–54 High-performance weather-protective £ashings Kim Robert LisÖ 1,3 ,Tore Kvande 2 and Jan Vincent Thue 3 1 Norwegian Building Research Institute (NBI), PO Box 123 Blindern, N-0314 Oslo, Norway E-mail: kim.robert.liso@byggforsk.no 2 Norwegian Building Research Institute (NBI), HÖgskoleringen 7B, N-7491Trondheim, Norway E-mail: tore.kvande@byggforsk.no 3 Department of Civil and Transport Engineering, Norwegian University of Science and Technology (NTNU), HÖgskoleringen 7A, N-7491Trondheim, Norway E-mail: jan.thue@bygg.ntnu.no Typical problem areas associated with weather-protective flashing are identified, based on a comprehensive investigation of building damage cases in Norway. A total of 175 assignment reports associated with damaged flashing for the period between 1963 and 2001 are analysed. The investigation clearly shows that certain faults and deficiencies are recurring items. Windowsill/weatherboard flashings comprise as much as 41% of the building damage cases associated with weather-protective flashing. Damage in connection with parapet flashing comprises 27% of all cases included in this investigation. With few exceptions, instances of damage are located in Norway’s coastal areas. Existing flashing solutions in the Norwegian Building Research Institute’s Building Research Design Sheets have been further developed, based on the results from the analysis. Improved high-performance flashing solutions are presented for a number of typical problem areas. An illustrated summary of problems frequently encountered with different flashing variants is also presented. Finally, recommended best-practice flashing solutions for a number of typical problem areas are provided. The results will be implemented in the Building Research Design Sheets, and will also be used as a basis for the carrying out of new field studies and laboratory investigations. Keywords: building damage, building defects, building enclosure, building pathology, building performance, building stock, climate adaptation, climatic impact, durability, weather-protective flashings, Norway S’appuyant sur une enquête approfondie relative aux dommages causés àdes bâtiments en Norvège, l’auteur recense les problèmes types que l’on rencontre avec les solins d’étanchéité. Il analyse 175 rapports de mission portant sur des solins endommagés au cours de la période 1963–2001. Il ressort clairement de cette enquête que certains défauts et déficiences sont des événements récurrents. Quarante et un pour cent des dommages analysés concernent des solins d’étanchéité d’appuis de fenêtres et de parements. Les dommages causés àdes solins de parapets comptent pour 27% de tous les cas analysés. A quelques exceptions près, les dommages ont été observés dans des zones côtières de Norvège. Les solutions proposées par l’Institut norvégien de recherche sur le bâtiment ont été affinées sur la base des résultats de cette analyse. L’auteur décrit des solutions faisant appel à des solins à hautes performances et applicables dans un certain nombre de cas. Il présente également un résumé illustré de problèmes que l’on rencontre fréquemment avec divers types de solins. Pour terminer, il recommande des solutions basées sur les meilleures pratiques en matière de solins. Les résultats figureront sur les fiches techniques de l’Institut de recherche norvégien sur le bâtiment et serviront également de base à de nouvelles à mener sur le terrain et à des enquêtes en laboratoire.
