Study Finds Roof Tiles Dramatically Reduce Noise Pollution in the Home
A major research study has found that roof tiles outperform common alternatives in reducing noise levels that enter the home.
Conducted by the Cement and Concrete Association of Australia, the study found that roof tiles can reduce external noise by as much as 30 decibels, compared with a reduction of 12 decibels for sheet metal.
High density terracotta and concrete roof tiles were found to effectively reduce noise, achieving levels of sound insulation performance far exceeding the minimum required by the Building Code of Australia.
The sound insulation performance of a roof is the measure of its ability to reduce the amount of sound that is transmitted from the external environment, through the roofing material and into internal living areas. Concrete and terracotta provide the mass required to effectively reduce the transmission of sound, which means they’re better at insulating against noise from vehicles, air traffic, extreme weather, etc.
Most roofs reduce noise but because of their density and thickness, tiled roofs are particularly effective at blocking out low to medium frequency sounds - the relative frequency level of most sources of noise pollution affecting homes. In addition, a tiled roof can help minimise creaking and popping sounds which occur with some types of roofing as a result of temperature variations.
Commenting on the research Mr Michael Monro (Sales and Marketing Coordinator at Bristile Roofing) said “As well as being an excellent weather insulator, terracotta and concrete roof tiles have fantastic advantages in sound insulation. Homebuilders should consider this important factor when selecting a roofing material to ensure they choose a product that not only protects them from the elements but also insulates them against external noise.”
