We are having a loft conversion. Both the building control plans and our quote stated we wanted rockwool 100mm under the new floor. Instead our builder has just reused our old loft insulation (very old and patchy) and added a tiny amount of Knauf Loft 44 in places. Floor is now down and walls plastered.
Obviously we are not happy as we specified rockwool for fire and acoustic reasons. Building control came out for insulation inspection and didn't seem to notice this.
What are the implications? Do regs specify acoustic insulation? Or new insulation etc? How bad is it if builder has to pull up floor and redo? This won't be possible in ensuite as karndean floor going down in 2 days.
