How thick is a drylined wall?

Thickness depends on the system:

- Dot-and-dab on solid masonry: 30-50mm (plasterboard + adhesive dabs) - Independent metal stud (single layer each side): 75-100mm - Independent metal stud (double layer each side, acoustic): 150-200mm - Metal stud with services cavity for M&E: 100-150mm - Standard partition with acoustic insulation: 100-150mm - Fire-rated 60-min partition: typically 100-150mm - Fire-rated 120-min partition: typically 150-200mm

For Gillingham apartments where space is at a premium, we often use thinner 9.5mm plasterboard on independent stud to keep the cavity minimal. For Gillingham Victorian terraces, the trade-off is usually the other way — we use 50-80mm insulated plasterboard to gain thermal performance, accepting the 30-50mm room loss.
