Hi all - my house is built with cavity blocks (as opposed to a cavity wall) and is a bit of a nightmare to heat in the winter. I put new double glazed windows in and re-insulated the attic with fibre-glass, but this doesn't seem to have made a huge difference. I'm wondering if it's possible to use pumped insulation (beads, foam, etc) with a cavity block wall? I've read a lot of threads on this and another site, but I can't get a definitive answer. Some people say it's possible, others say the blocks would have to be perfectly aligned with no blockages from lumps of mortar, etc.
If it's not possible to use pumped insulation, can anyone recommend another way of insulating a cavity block house? I know there is the external plastering/paroc block type systems but these seem to be pretty expensive. Any thoughts / ideas greatly appreciated.
