Hi,
After years of suffering from a very cold hallway (late 20s end of terrace solid walls) we are going to take the plunge and fit some internal insulated wall boards.
Unfortunately we do have space issues - the stairs are quite narrow as it is - and will only have about 40mm max to play with. I have looked at GTEC Thermal XP and Knauf XPS wall boards. Both are 35mm thick of which 9mm is the plasterbaord. I know in an ideal world we would fit 100mm thick boards but this is just not possible.
I am intending to mechanically fix these to the wall and then paper over with thick lining paper.
Are all of these type wallboards pretty much as good as each other? Do people think wallboards of this thickness will make any differnce at all?
Thanks
