Green Roof Noise Reduction

This may not seem much but for the human ear an 10 db reduction in noise levels is 50 quieter.

Green roof noise reduction.

Green roofs reduce sound resonance by 3 db and provide sound insulation of up to 8 db. This is a step that is generally taken retroactively as it is not necessary when a roof is installed with the proper type of roof underlayment. Reduces ambient noise outside and inside. Thanks to this cooler roof the efficiency of solar panels is higher and so you reduce your total energy costs.

They also have a sound absorption coefficient of about 0 40. If you have a noisy roof and want to do something about it you could always install a layer of insulation.

Green roofs have excellent noise attenuation especially for low frequency sounds. The degree of sound insulation will depend on the thickness of the green roof structure. Green roofs can increase a building s marketability. Generally speaking green walls provide a 15db reduction in sound.

Urbanscape is a cover name for a range of new innovative products concepts and systems which can be used in numerous applications. Given a single edge diffraction higher frequencies are relatively more important and these are reduced to a larger extent by the green roof. Have an in depth look into our green roof purple roof landscaping or green designs on the move concepts to find out more. Green roofs have the greatest potential for attenuating noise and on certain roof shapes may be able to reduce noise by up to 7 5 decibels.

In effect replacing a standard roof with a green roof can shield road traffic noise by up to 10 dba. At lower and thus shielded parts significant road traffic noise reduction is possible by the green roof exceeding 5 dba at 70 km h 1 see van renterghem and botteldooren 2009. The international green roof association igra indicates that on average your green roof can reduce sound reflection by up to 3 db and improve sound insulation by up to 8 db.
