    How to tell if loft joists are strong enough?

    Hello, I'm just wondering how to tell if the joists in your loft are strong enough, whether just for storage or to use as a regular room? I'm partly asking because we would like to eventually board the loft void above the rear part of our Edwardian house to use for storage, after insulating...

    Insulating loft which you later plan to convert

    Hi, I have a c. 9x8m loft in a 1860 ish Victorian house which I'd like to insulate now*. As you can see from the below, it's barely insulated, but is currently "cold roof" construction. 1) It's possible I may ultimately end up doing a loft conversion (in maybe 5+ years). It'd be preferable...

    i have 170mm joists, and I want to board an area 1.2m x 2.4m . i was thinking of using C24 untreated timber which is 90mm high, so I’d get 260mm of fibreglass insulation plus the OSB boards on top.
