About to do some insulation work and trying to figure out if it would be worth pumping my cavity walls with beads ?
I live upstairs in a (2004 build) Duplex apartment, Concrete slab floor, I have been told by an Engineer that its probably 100mm cavity and 50/60mm expanded polystyrene insulation inside, pumping would give me an extra 50/40mm of insulation. Roughly double the insulation.
Worth it ? I heard the outer leaf can remain wet once the cavity is gone ?
