I have a 30 year guarentee certificate that was dated in 1977 for ICI Cavity Wall Foam insulation installed in my house. Is there likely to be a need to top up the insulation or renew it with a more modern variant - assuming that there is space for any more. Any guidance would be appreciated.
Advice Please: 30 year + ICI Foam Cavity Wall insulation

i'm not familiar with the foam insulation but have been looking into having cavity wall insulation fitted myself.
the guarantee would have been an indication of the quality of the product used and the methods to install it.
i can't imagine that u will need to do anything with it. they are aimed at the life of the building. it would also be very difficult practically to do anything.
If u need any further assurance then u would need to contact the installer or whoever the part of ICI is now.

In my experience foam has not lasted over the decades and has started to crumble over the years.It appears that the foam may shrink so it nolonder touches the inner wall. When I take windows out of houses I often find voids where there is no foam or find that the foam when touched turns to dust.
I believe there is a new method of blasting this foam with compressed air and removing it from the cavity so that modern polystyrene beads can be installed in the place of the foam.
While this might be slightly expensive the homeowner that I have experience of,described a warmer home.
