I desperately need to increase the thermal properties of my 1860's 9" solid brick walls after receiving an enormous electricity bill for last winter and am considering using phenolic backed(30mm) plasterboard - tradename "Kingspan" - glued directly to the brick after removing the original plaster. Has anyone any experience of this type of internal wall insulation - are there any unforseen horrors? Are there any better ideas for IWI, my cottage is small so space is at a premium?
