i am going to put a raised floor in my loft to accomodate for insulation i am having put down, i have three 6x2's running from gable end to party wall, can i put joist hangers on them and hang new joists from them to make the raised floor area or can this not be done. There is three of them running threw the loft each from gable to party wall, one in the centre of the loft the other 2 are running threw about 6 foot away from the centre so my overall new joist span would on be 6 foot as i could hange from either side of the big centre joist. any input would be very very much appreciated
