There will be diminishing returns of course, but at what thickness is it pointless doing more.
When we built our timber frame house in 1995, 100mm was very much the norm. We went for 150mm, but there was also talk of 'spaceframes' being 300mm or more thick.
At what thickness of insulation does reducing the U-value stop? I know there are variables, but generally? Only asking from interest.
