Rain noise
Rain can cause unacceptable levels of background noise during class, seriously impairing learning and concentration. The problem is particularly acute with lightweight roofing commonly used on school buildings. The issue has been recognised in BB93, as well as other best practice codes and guidelines.
Rockwool and its sister company Rockfon ceilings commissioned the Building Research Establishment to carry out a series of tests using the newly-created ISO standard for measuring rain noise on building elements (BSEN ISO 140-18:2006).
These demonstrated that Rockwool insulated roofs, with the addition of a straightforward Rockfon low-weight stone wool suspended ceiling, will fully satisfy the relevant criteria for rain noise resistance, reverberation time and speech intelligibility. It can attain the same level of performance as a more complex and costly multi-layer ceiling.
