The insulation was followed by a layer of 12.5mm plasterboard.
Some thinking was required here to not only stagger the joints on the plasterboard sheets but also to try and make sure they didn't coincide with the edges of the insulation boards. This was mostly successful, but there are a couple of places were both end at the same place.
One other complication was that the Celotex had been around here for a while and having been stacked not all of it was exactly the same thickness, or compressed by the same amount when the plasterboard was screwed up tight. This has lead to a few undulations, but nothing too serious. |
