    Default Can I remove these

    Hi,

    I'm about to install some underfloor insulation in a 1950s double brick home.

    These supports (see photo) are in my way. I suspect that they were there to keep floor joists in the right spot before flooring was added? And also to stop the tas oak joists from warping if they weren't entirely dry.

    Can I remove them? All thoughts very appreciated.

    Cheers

    short answer -- nope

    structurally those braces are to stop the floor joists "falling over" which they can do even after the floor is added

    No, they are a structural element that adds to the torsional rigidity of the floor and as Ian said they stop the joists rotating under load.
    The technical term is herringbone strutting and is rarely if ever used today as it is fairly labour intensive and much slower to do. The method used 99.99% of the time now is solid bridging, ie: a slide block of wood 20mm narrower than the depth of the joists and centered so there is 10mm clearance top and bottom to allow for air circulation and eliminate high points in either the floor on top or a ceiling underneath as well as squeaking (when traffic on the floor rubs on the top of the solid bridging.
