Hi guys,
Planning to build a single story rear extension and was chatting to a builder the other day who suggested using the wider (I think they're 300 mm) blocks with insulated plaster board on the inside and render on the outside. I know that old school builders would say that a double skin with insulation in the cavity is better, but will the wider blocks do the job? Once rendered, does it really make a diference?
I have driven past a number of jobs where the wider blocks are being used.
Also, to make the most of space, surely, a double skin of 9 inch blocks and then plaster board on the inside is goign to be thicker than the wider block option.
Any ideas or advise would be helpful.
Thanks
