They are the improved version of Inferior Walls .
Actually they are precasted concrete foundation panels.
I think that they have built in strips for screwing the finished surface.
But I though that they also had some kind of insulation.
The OP needs to give some detailed specs on what he has.
Also check the supiro walls website for any information tthat they have on finsihing walls.
