The use of thermography in the building industry.

Describes operation of thermal imaging cameras with a display monitor detecting infra-red radiation. Since temperature differentials of 0.20C are significant for insulation of buildings, camera must be used to limits of its sensitivity and monitoring procedure must be carefully chosen. Treats measurement limitations in field of building. Uses details of thermographic surveys to illustrate some difficulties of measurement and analysis. Emphasises importance of correct inspection procedures for particular situation. Notes likelihood of thermography being included in statutory inspection of buildings prior to certificate being granted confirming acceptability of thermal insulation standards.
