    In a standard-sized 3-bedroom semi-detached house where under the floorboards of the ground floor has been insulated and also between the floor joists of the attic (not the roof joists) has been insulated, is there any point in insulating under the floor of the 1st floor? i.e. under the floor of the bedrooms?

    Thanks!

    Generally, no real thermal reasons but there may well be acoustic reasons

    If putting this in then purely for acoustic reasons, would there be a product more specific to this than insulation?

    I'm not an expert but rockwool is usually good.
