November 24, 20232 yr Is it possible to vacuum extract chopped fibreglass from a 50mm cavity and then have it replaced with blown beads? Recent renovation work has uncovered areas of the cavity that are poorly filled, and as this is our forever home, I’m keen to have the insulation replaced with something that’s going to last long term. Not concerned about moisture as it’s rendered blockwork.
December 1, 20232 yr regarding the choice of beads: we've recently been trying to find out whether we should install beads or wool after extracting the current CWI Most of the installers who attended said they used to install beads but do not anymore because it's too difficult to do it properly... I left some details at Hope that helps Edited December 1, 20232 yr by abernabei
