Why are you removing kitchen to install insulation? Why don't you get cavity insulation pumped in ,if you haven't got cavity walls you can have ewi Installed this is insulation stuck on the outside walls then rendered ,it has a great u value and keeps you nice and warm keeping your bills down and cool in the summer a bit like a thermos flask. I'm working on one in Kidderminster it's a great system and means there is no upset inside the property.
