The document discusses different types of partition walls used to divide interior spaces in buildings. It describes timber stud, metal stud, drywall, glass block, and block partitions. Timber stud partitions can be plaster skimmed, dry-lined, or partially glazed. Metal stud partitions are lightweight but strong, consisting of a metal framework covered in plasterboard or fire-resistant sheeting. Glass block partitions are made of translucent glass blocks laid in mortar, sometimes with reinforcement. Block partitions are constructed from masonry blocks.
