FIS is becoming increasingly aware of issues where ply has been used in the construction of drylining. We would like to advise our relevant members to be aware of the issues and look for ways to mitigate the risks rather than carrying out costly and time-consuming remediation works, often after occupation of the building.
For more information, please read an article which appeared in FIS SpecFinish, or contact FIS Technical Manager, Joe Cilia on joecilia@thefis.org
We have been advised by Robust Details that there have been instances where the resilient layer used to reduce structural sound transference between residences on different floors is being cut before the installation of the drylining. This is having a significant impact on the acoustic performance, and we have been asked to advise the sector of the correct method of installation where this resilient layer is present.
The resilient layer will be present around the perimeter of a room where a screed has been installed and should be placed against the floor prior to the installation of the drylining, any skirting should be installed prior to trimming any resilient layer still showing before sealing with acoustic sealant.
Robust Details has provided a technical note (available here) which includes links to clear and informative videos explaining this process. Should there be any doubt please consult with Robust Details or the site manger before removing any resilient layer on site.
