WALLS<br />
• Drywall System<br />
<strong>Sustainable</strong> <strong>Construction</strong> -<br />
In recent years, many forward-looking developers have used the dry wall system as internal<br />
partition walls for residential projects. The dry wall system consists of dry boards (non-combustible<br />
plaster boards or fi bre cement boards) attached to metal studs and sound-insulated by rockwool.<br />
Can drywalls be used as party walls?<br />
Drywall system can also be used as a compartment wall or party wall separating 2 dwelling units,<br />
provided that it meets the fi re resistance requirement. Designers should select drywall systems that<br />
are certifi ed under the PLS.<br />
Drywalls can also be used to construct protected shafts, provided that they meet the performance<br />
criteria of:<br />
Impact (BS 5588 Pt 5 Appendix A) Deflection (BS 5234 Pt 2)<br />
30<br />
Water Absorption and bending strength<br />
(BS 1230 Pt 1 – gypsum plaster board)<br />
(ISO 1896 – calcium silicate/<br />
cement board)<br />
For use in lift shafts, the drywall system has to meet an additional<br />
requirement of cyclic loading and dynamic test as specified<br />
under Cl. 3.3 of <strong>Building</strong> Code of Australia Specification C 1.8.
