Description of BS 9250:2007 2007This standard provides guidance on methods that can be used to meet the “well sealed ceiling” requirements defined in BS 5250 for cold and warm pitched roofs. This standard provides architects, house builders, and building control officers with robust design details for the construction of more airtight ceilings and for the control of air movement into pitched roofs. It provides guidance for dwellings and buildings of domestic type construction on the selection of materials, design principles, construction methods and design details covering: the junction of walls and ceilings; junctions of ceiling materials; penetration through ceilings (e.g. pipes, outlets, cables, light fittings, loft hatches, tubular rooflights and roof windows). It includes cold and warm roof applications and will apply to new, and the refurbishment of existing, buildings.
