Understanding Damp and Condensation in Buildings

Dampness is a persistent and widespread problem in the UKs’ housing stock, affecting properties of all ages and types. For retrofit professionals, understanding the nature, causes, and consequences of damp is essential not only to identify existing problems, but to ensure that any retrofit measures, such as insulation or airtightness improvements, do not inadvertently worsen moisture issues. Damp can compromise the structural integrity of buildings, undermine energy efficiency, and degrade indoor air quality. Moreover, there is a well-documented link between damp environments and poor health outcomes, particularly respiratory illnesses such as asthma and bronchitis.
