Hi everyone
We are currently renovating a house and are about to start insulating the solid 9" external walls with K18 insulated plasterboard.
One question - what thickness do you get? What difference is there between the thinnest and the thickest?
With Building Regs for the loft, we believe you put in 30cm of loft insulation in. What is the equivalent for the solid wall insulation?
Thanks in advance
