Best Internal Insulation for Concrete Roof to Avoid Loosing too Much Height? Information, help, tips and advice on cavity walls, ceilings and lofts etc....

[Down2school]

We have an old school with a converted toilet block whose ceiling we wish to insulate. The present insulation is polystyrene tiles; we want to fit a beaded T&G ceiling, and would like advice about the best replacement for the polystyrene, before covering with the T&G. We want the finished result to reduce the height of the ceiling as little as possible.

We have been considering Thermawrap Multilayer insulation; any advice would be much appreciated.

Thanks.
