You are *sure* it is a dry wall?



eh?



Cellar walls are rarely dry, unless the cellar has been properly tanked.

yers

Even if the walls feel dry it that'll be because the damp has
evaporated... Cover the wall and you need to think about the damp that
will build up behind it.

or make arrangements for it

Rot proof string is probably the simplest support. Spaced around 12" and
stapled to the side of the studs and inch in so that the batts are
*slightly* proud of the front side of the studs to elimnate any gap
between them and the PB. A gap would allow a draft and partially defeat
the object of the insulation.

if the batts butt up against the studwork where would a draught get in/out?
