Getting the right mineral wool insulation

Keep it ventilated

When insulating a loft, keep eaves vents clear so the roof space stays ventilated.

How much for a loft?

The common recommendation is 270 mm in total: usually 100 mm between the joists and 170 mm across them. Check the depth already there.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.
