I have just put in some new loft insulation between the extisting joist, in order to meet the minimum requirement I would like to put extra insulation at 90 degrees of the existing loft insulation. the problem I have is that I have existing pipes over the existing joist and would like to riase the joists by putting 4 x 2's at 90 degrees of the existing joist. and then put up loft boards.
My existing joist run paralel to the wall and I live in a mid terraced house.
Will I have enough support to do this? and also what distance do i need to have between the joists.
I will be using the joist as storage space.
