  • After much procrastination, cold weather has made me want to finally sort my loft out. I haven’t really been up there since I got the house, but looking now and it looks like the previous owner has done something….weird.

    Picture attached shows the general idea. Yellow is insulation beneath chipboard floor boards. It’s pink fibrous stuff, and stuffed between joists so probably 100mm or less.

    Pink lines are the weird bit. He’s built a stud wall and it looks like the same pink insulation is in there behind plasterboard. On the roof, it looks like that insulation has been put between the rafters then boarded over with plasterboard. Then the whole lot (roof and walls) covered in carpet underlay (?!).

    The ventilation in the side bits is good, but I’m guessing the middle part being insulated and boarded over is not good for the rafters.

    I’m guessing my best option is:

    1. Pull down the plasterboard and insulation from the rafter area
    2. Add 200-300mm insulation to the yellow area.
    3. Get loft legs and re board the middle yellow area for storage.

    I’m wondering if I should pull the stud walls down too.

    I’m guessing it’s not really possible to avoid pulling down the stuff on the rafters?

  • the middle part being insulated and boarded over is not good for the rafters.

    There should be ventilation between the insulation and the roof - I think that's the biggest worry you have there.

    Other than that, and carpet on the walls, it seems reasonable enough.

    Moar insulation in the eaves is good, though, but remember to leave the soffits unblocked.
