This in-situ test took place in a case study dwelling located in the City of Perth in Perthshire, Scotland. The property is representative of many un-insulated homes that suffer from low thermal comfort. Walls in this property consist of an external roughcast, block wall, cavity, building paper and a timber frame with plasterboard dry lining. 


The in-situ fabric performance monitoring consisted of baseline tests prior to work commencing and post-intervention tests once the foam was applied into the cavities. Monitoring included in-situ heat flux measurement (U-value), infra-red thermography, air tightness testing and static (Glasier method) interstitial condensation modelling as a baseline followed by in-situ vapour pressure measurements after intervention.  


Additional to the study was the monitoring of indoor air quality consisting of temperature, relative humidity and formaldehyde concentration. Equally, it was vital to record baseline in addition to actual figures during installation and the curing process. According to distributors and manufacturers of the product, kiln-drying the UF removes free formaldehyde and stabilizes the resin into a dry powder, hence reducing any environmental and health implications (Edmunds, 2013). 

The final testing procedure consisted of measuring baseline and post intervention insitu and laboratory acoustic performance. This work was performed by The Robin McKenzie Partnership (RMP).
