The Gyproc handbook organises drywall by design criteria such as height, thermal insulation, fire, acoustics and robustness; that is the correct way to select a system before choosing board colour/type.

Gypsum, Partitions & Ceilings
Drywall and suspended ceilings are tested assemblies, not independent boards. Performance depends on framing size/gauge/spacing, board type/layers, insulation, fixings, joints, perimeter details, penetrations and movement interfaces.

What this activity is
What this activity is
Gypsum systems use metal framing, boards, insulation, joint treatment and accessories to create partitions, wall linings, ceilings and architectural forms. Performance comes from the tested assembly—not the board alone.
What to expect
Expect the correct board / stud system to be selected for the required height, loading, fire rating, acoustic performance and moisture exposure. Services, backing, access panels and heavy fixtures must be coordinated before closure.
01Choose the system by height, duty, fire, acoustic, moisture and loading criteria
02Set out tracks/angles from surveyed datums
03Install framing at the system-specified centres and bracing
04Coordinate services, backing and insulation before closing the second face
05Stagger and fix boards to the tested/system detail
06Complete jointing, perimeter seals and final inspection before decoration
02 · ENGINEERING FUNDAMENTALS
Understand why the system behaves the way it does.
01
Thermal resistance R = t/k and U ≈ 1/ΣR for a simplified layered system; actual assemblies include surface/cavity effects
02
Partition lateral deflection criteria and maximum height depend on system test/design data, stud size/gauge and spacing—not a generic one-size rule
03
Acoustic isolation improves through system effects such as separated leaves, cavity absorption and multiple layers; mass alone is not the complete model
Service penetrations, sockets and access panels are weak points in fire/acoustic construction. Coordinate tested details and avoid back-to-back openings where performance would be compromised.
Ceiling grids must not become accidental supports for heavy MEP equipment unless the selected system is specifically designed for that load. Independent supports protect both safety and ceiling alignment.
