Roof and loft insulation guide

6 · If you plan to use the loft or attic for storage, you will want to lay boards over the joists. Unfortunately, if you only insulate between the joists before doing this, the insulation won''t be thick enough. To get enough insulation, you can raise the level of the floor so you can fit enough mineral wool beneath the new floor level.
