Laminated partitions

This type of partition consisted of three layers of plasterboard. It was quickly assembled and provided acceptable sound insulation and fire protection for housing. The outer faces of the partition could be plastered, but it was usual to use ivory-faced wallboards for direct decoration, with tapered vertical edges of the boards for jointing with a special compound, as described in Chapter 10 on plastering. As with the Panelwall system, the partitions were not loadbearing. The thickness of the partition was usually 50mm, but where extra sound insulation or fire protection was required thicker partitions could be made by using extra and/or thicker boards.
