Insulating a loft with only 70mm high joists!!! Please Help!

Postby gihan » Wed Oct 22, 2008 8:48 am

Dear all,

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

you could use 50mm kingspan insulation or similar.

the battons you fix along the existing joists will only strengthen the ceiling
not weaken it.
