  • 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?

  • Sure you want to pull down those stud walls?
    Presumably they are supporting your rafters, tiles etc… they are far from ideal as they are (also presumably) transferring the load of your roof to the middle (weakest point) of your 1st floor ceiling joists.
    But if your roof is still vaguely triangular then they are getting away with it.
    If you take them out and there are no other visible means of support for your roof then it may well stop being triangular quite soon.

  • I don’t believe they’re holding any load - there’s a purlin on each side which supports the rafters, and a diagonal strut which runs from the centre wall in the middle of the house up to each of the purlins. Those struts had been removed at some point (presumably to open up the space for use as a room) but have been added back in by my builder when we got some other work done.
