We've constructing a 11.5x6.5m log cabin, which sits on a wooden raft (suspended floor basically). When we got quotes to insulate the floor with 150mm kingspan boards, we were taken aback to see materials costs quoted £2-3k!
I'm wondering what the minimum insulation we can actually get away with. Is it based on u-values?
If we mentioned the insulation type in our planning application, will anyone care if we modify this if it still meets regs?
