I'm insulating an internal wall. The wall is flat. I was going to
use no more nails to stick the board to the wall. Will that be
sufficient? Or should I erect a timber frame and nail it to that?

By the way, I have had a lot of trouble trying to find insulation
board. Could someone recommend a good brand, depth and supplier.

Kingspan, Celotex for a start.

Depth depends entirely on how much insulation you need, ie what you're
trying to achieve.

A good supplier is:
http://www.secondsandco.co.uk/ - they sell literally 'seconds' quality
insulation a lot cheaper than you're likely to get it from a builder's
merchant.

Ah - sorry, just spotted your other post - it's the inside of an
external wall...

Depends on the thickness you want, and how you plan to cover the
insulation after.

For upto 30mm youy can stick it on, and then screw plasterboard to it
right through the insulation and into the wall below, although even then
some thin battens would give you something to screw into (easier than
plaster anyway). Alternatively you can get PIR foam boards already
bonded to sheets of plasterboard. These would probably be quickest and
simplest and let you use thicker insulation layers simply.

If you want lots of insulation then you could erect a 4x2" framework
first, stick 100mm sheets (or two layers of 50) between the studs, and
then either plasterboard over, or even add another layer of insulation
over first the PB and skim.

Thanks John. What does PIR stand for? Also would you always recommend
screwing into the wall rather than using an adhesive?

PIR is a shorthand for Polyisocyanurate foam - the foil covered type of
rigid urethane foam that gets sold under brand names like Kingspan or
Celotex... there are quite a few makers of the stuff - many less well
known but much cheaper than the aforementioned two.

Screwing - its an easy way to fix the plasterboard, but you may be able
to bond that to the foam instead if you prefer. (no point is screwing
just the foam - the screws will pull through it too easily if not backed
up with something more solid over it).

I used ECOTHERM on my build, cheaper than the big brand names but just as
good.

Yup, twas what I was about to say - used that myself. (Paid £14/
8'x4'x2" sheet when Jewson were quoting over £30!)

Ruberoid is another one.

Check with one of the suppliers of "seconds" like
http://www.secondsandco.co.uk/
