Hi,
I am simulating an existing masonry cavity wall which appears to have full fill mineral fibre insulation in the cavity (built in UK in 1980s). I am looking through the WUFI data bases for a similar product, what would be suitable?
Isover supply a glass mineral wool bat in the UK called Isover CWS 32 and 36 which are water repellent to prevent the passage of water across the cavity. I couldn't find an equivalent Isover product in the WUFI database, which one would be closest?
If these types of products are not included in the WUFI databases, can I simulate using mineral wool with a breather membrane between the outer skin of masonry and the insulation to prevent water from passing from the brick into the insulation?
Thanks
