How can I achieve a Severe Duty rating?
To achieve Severe Duty, you will need to meet as a minimum the lateral stiffness and impact resistance criteria as set out in BS 5234 Part 2. The maximum height of a partition is limited to a lateral deflection of 10mm when tested in line with this standard. Impact resistance is down to board selection. Any combination of two boards (at least 12.5m
-
Which plasterboards give the best impact resistance?
Siniat LaDura, Megadeco and Universal boards offer the best impact resistance. The 15mm version of each used on a partition system as a single layer will provide Severe Duty assuming the maximum height is within recommendations.

Does Siniat have a board that can achieve severe duty and offer moisture resistance?
Any combination of 2 layers of 12.5mm/15mm plasterboards each side of a stud frame will be classed as Severe Duty. To achieve Severe Duty with a single layer each side of the stud frame would require the use of 15mm LaDura, Universal, Megadeco or Aquaboard. Of these, LaDura is classed as H1 moisture resistance to BS EN 520, Aquaboard is classed as G

What is the maximum door weight Siniat partition systems can support?
For single stud or twin frame partition system, the door jamb detail can be configured to support up to 100kg for a door leaf. The principle of the details are shown below: In order to support heavier door leaf weight, an square hollow section is recommended to form jamb and lintol designed and supplied by others. For a shaftwall system, the maximum

What crowd load can a Siniat partition withstand?
The published heights of Siniat partitions are constrained by the minimum values of Serviceability Limit States (SLS), Ultimate Limit States (ULS), and a 10mm maximum deflection requirement outlined in Annex A of BS 5234-2. These stringent height requirements, coupled with crowd load testing conducted in accordance with BS 5234-2, have led to the d
