Monitoring CLR Results
Tim Martel, MCIAT CEPH
The AECB monitors 10 sites for the CarbonLite Retrofit programme and Simmonds.Mills monitors 2 for commercial clients. This presentation will look at a project near Huddersfield. Mineral wool internal insulation was applied as IWI to a cavity wall assembly and we look at how it has performed. Essentially there are 2 main questions: (1) is the insulation working safely? And (2) if not, where is the moisture coming from and how? These two questions are answered through estimates of mould risk, vapour gradients, capillary gradients, moisture is taken up by materials from the air and diffusion.
