With increasing levels of insulation, the use of impermeable cladding materials and
new methods of construction, can at times increase the risk of condensation in buildings.
Condensation can give rise to a range of problems from surface staining of internal
finishes to long term degradation of the structure. Recent health scares from 'toxic
mould' growth in buildings have also highlighted the dangers that may be caused if
Condensation Risk Analysis in accordance with BS5250:2011 and BS EN ISO 13788:2002
standards assesses the risk of both surface and interstitial condensation occurring
for different constructions.
