Dr. Oliver Kinnane:

The reality is we are already retrofitting the retrofits. There is lots of anecdotal evidence and lots of actual evidence that a lot of retrofitting was done inappropriately. That has caused problems, especially with traditional construction, with heavy moisture content within envelopes. Many vapour-impermeable products are being used to retrofit those buildings all the time and this is trapping moisture, allowing for growth of moulds and mildews, creating bad air quality and creating poor health conditions for people. We are seeing a lot of that already and it is generally due to a lack of knowledge across the industry and a lack of training for a long time, which we are trying to correct now. Again, it emphasises the point we really need to train the installers ahead of installation because dealing with different buildings of different construction types is not something every contractor has in their understanding. That is what they need to be trained in before they implement installations, otherwise we will end up pulling those retrofits apart again.
