A normal metal roof subjected to heavy rain or hail can cause serious noise problems for both the rooms below and for those adjacent.
The Ondulit multilayer protected system is the only one that has a thick layer of sound proofing placed at the extrados of the sheet.
This protective layer absorbs the impact of the rain or hail on the plate and prevents the vibration, cause of the rumbling effect.
The covering so does not produce any sound. In addition, the Coverib sheets have a capacity of 28 dB sound insulation.
The sound proofing capacity of an Ondulit protected steel roof is approximately 8,41 times that of a simple sheet.
