hi
i am currently insulating the walls in my house, my neighbor tells me he
done so in the following way
First putting a breathable membrane on the wall, then screwing battens at 600mm spacings then filling the gaps with 25mm polystyrene and screwing plasterboard to cover
I have done this in one room put have not yet skimmed
since starting i have looked into the methods and now i am unsure which way to go,
my first question is should i put the breathable membrane on first or after the insulation
is breathable membrane classed at a vapor barrier or am i using the wrong stuff.
and while we're on the subject of the walls what are your thoughts on blocking up vents, people say don't but its like having a windows open, not good in winter
i would be very gratefully for your time and any input
Thanks
