Moy Isover Acoustic Roll

Acoustic Roll

Moy Isover Acoustic Rolls are lightweight glasswool rolls manufactured in Ireland. They are available in a wide variety of thicknesses, lengths and widths. They are suitable for thermal, acoustic insulation and fire resistance in walls and roof spaces in domestic, commercial and industrial buildings.

Moy Acoustic Rolls are widely used for noise control purposes in a variety of applications as its lightweight, fire-safe and robust nature is combined with highly efficient sound absorption.

Sound Insulation and Privacy

In designing for sound insulation it is important to set targets which are correct in terms of the uses of spaces separated by partitions and walls.

Table 2: Degree of Acoustic Privacy

Rw	SPEECH LEVEL
25dB	Normal speech can be easily overheard
30dB	Loud speech can be heard clearly
35dB	Loud speech can be distinguished under normal conditions
40dB	Loud speech can be heard but not distinguished
45dB	Loud speech can be heard faintly but not distinguished
More Than 50dB	More than 50dB Loud speech or shouting can be heard with great difficulty

Table 2 compares Acoustic Privacy with the weighted Sound Reduction Index (Rw).
