Book Description

Level thresholds, where the internal and external walking surfaces are level, or almost level, are increasingly being specified to give access to the elderly and disabled. Level thresholds present a potential weakness in the weatherproofing resistance of door openings which may let water in. There is also a risk of thermal bridging. This Good Building Guide describes some of the technical risks associated with the design of level thresholds and some detailing solutions.
