Full fill masonry cavity wall insulation

Post by pdp » Sun Apr 26, 2015 10:43 pm -1100

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
