Insulating a loft that’s already boarded
Existing boards usually hide thin insulation. Here are the options.
Lift and insulate
Boards come up, insulation goes between the joists, and a raised floor goes back on top.
Boards between the joists
Where depth is tight, rigid boards can go between the joists under the existing floor.
