I want to insulate the loft space in my 1890's built maisonette. I have read that current regulations state you should insulate to 270mm. Unfortunately the joists are currently only 70mm higher than the below ceiling.
I intend to place loft boards up there to use it as a storage area (maisonettes have very little storage room).
I have heard that you can fix batons along the original length of joists, but won't the extra weight of the batons[b]plus[/b] the loftboards [b]plus[/b] the general household stuff that i'll be storing up there, cause a weight issue to the celing below??
Please help as I'm only moderate DIY'er and have no idea of how much weight these old joists can hold.
I thank you kindly in advance for any replies received
