Subtitle: 

Ref Code: GG47
Authors: C Stirling

Abstract1: 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 at the threshold. This Good Building Guide describes some of the technical risks associated with the design of level thresholds and some detailing solutions.
