How insulation is wrecked by electrician crawling though the roof. You can see the batts just chucked around and not in place - Just 1% gaps in batts reduce their efficiency by as much as 30% and if the installers leave 5% gaps then the effectiveness of the insulation can drop by 70% ... Sure, their should be no gaps but whether it is the installers or electricians that come in latter you can see plenty of gaps in this job.
