Will ask my OH later for you, if you like. He is a retired architect and chartered building survyor. Just for what it's worth, I would think possibly the wall should be constructed of plaster boards with those metal grid things that they use so often in France. To the grids you then attach insulation materials.
You then have the insulation materials as well as the air space in the cavity and both should provide excellent insulation.
Cheapest,quickest and easiest way is with metal studs, put your base plate on floor.plumb up to fix a head plate right across the roof,fixing wherever and as much as poss. The metal uprights click into each other so you can extend to whatever hieght you want,also the big bonus is that they don't warp/bend/burn and are insect proof.You can use 400mm or 600 mm centres and crimp-fix tops and bottoms as you put boards up. Do one complete side,install any cables required inside convoluted trunking before putting required insulation in ,then board the other side. For extra strenght ,fire resistance and soundproofing you can double board interior side so that board joints are NOT on same studs.
Regards.

Unfortunately, the two are not seperated as can be seen below.It is my intention to build a wall from where the ladders are leaning, across the barn to where I am taking the photo.As this will seperate warm from sometimes bl%%*y freezing, what is the best method of construction to ensure maximum thermal efficiency?

The OH has had a good look at your photo. Says there are various ways of achieving your purpose. However, you need to be careful how the wall is constructed; you need to "stagger it", putting in bays or even put a load on top of it, otherwise a wall of this size is not stable. You might also need good foundations for it.
You could also build it up as Steve (Powerdesal) has suggested up to first floor height and then use lightweight materials above that which will allow you to build the wall to the shape of the barn roof.
Most important of all, he says there is insufficient information to advise you conclusively. However, I will pm you with our telephone number and he says he is happy to have a chat with you about it (no obligation, of course).
Cheers
How about wooden frame and straw bales, then render ? You seem to have lots of space and they are cheap and thermally efficient.
Happy building
