A dormer bedroom in my bungalow has plasterboarded stud walls backing onto
unheated voids. I have access to the backs of the walls and want to
insulate them.



My first thought is to fix cellotex panels, cut to size, in the gaps between
the studs.

If I do this, what is the best way to hold the cellotex? Builder's tape or
nailed battons come to mind, but are there are better ways and are there any
special issues related to fire regs?



Alternatively, is there a better way than using cellotex?



Cheers



Steve
