My house was build in 1908 and has solid walls. In the next month or so I will be stripping the old plaster from the inside of the front of the house and I want to replace it with plaster board that is backed with 1inch of insulation, it is a Kingspan product.
Does anyone know if this can be fixed direct to the bare wall, and if so how? Has anyone done a similar project before?

You checked here, right? http://www.insulation.kingspan.com/literature.htm

There are 2 'normal' ways to fix plasterboard to the wall.....either batten and screw (looking at probably half inch wooden battens horizontally, which will give you a nice airgap as well to reduce heat loss further and reduce damp transfer) or dot and dab (where you just dot 5 or 6 blobs of plaster on the back and press against the wall)

Personally if you are DIY-ing i find batten and screw much easier and simpler as well as more effective...but you lose a bit more of your room.

Following up on Para_medics comment

It looks like Kingspan do a different board for each fixing type...so make sure you decide which you are doing and then chose the correct type...K17 for dot/dab and K18 for batten.

Another bonus of battening is that you can run the electrics behind it more easily....as you can tell I'm not a fan of dot/dab.

p.s. i've done this before if you want to PM...happy to pass on my mistakes.

Don't you have to nail battens to the wall and then install a vapour barrier? Otherwise, the warm, moist air passes through the plasterboard, condenses on the cold wall and runs down to the floor where it festers and creates the ideal conditions for dry rot!

Ok, that link seems to make it clear, thanks.

Not if one buys the right kit, apparently.
