Am about to fill in an internal downstairs doorway ay home using blocks, and am looking at the various different types.
Am I OK to use one skin of those very lightweight (cheap, convenient!) aerated blocks for this or do I need to use heavier stuff? The door lintel will remain in place so they won't be load-bearing, and there's no sound insulation issues that I'm concerned about.
The existing wall is old brickwork, and I was planning on wet plastering one side of the old doorway, flush with and to match the rest of the wall and minimise risk of cracks; and dryline the other side, which will actually form an alcove (due to the depth of the old wall) into which I will be fitting shelving at some point.
Have I got this about right?
Thanks
