The World Health Organisation(WHO) recommends an ambient noise level of below 35dB for a good night's sleep. The acoustic danger threshld has been set at 90 dB. In excess of 105 dB, irreparable hearing loss may occur. The threshold of acoustic pain has been set at 120 dB. Above this, noise becomes unbearable, leading to extreme pain and hearing loss.

Noise is blame for:

-11% of accidents in the workplace;

-15% of lost working days;

-20% of psychiatric hospitalisation admissions.


SGG Stapid Silence is a laminated sound-insulated safety glass. It is composed of two or more layers of glass assembled using one or more films of sound-insulated polyvinylbutyral: sound-insulated PVB or PVB silence.

The acoustic performance of glazing was improved mainly by increasing the thickness and asymmetry of glass panes in double-glazed units. In certain cases laminated safety glass would behave almost like monolithic glass of the same thickness. On average it is possible to improve performance by 1 to 3 dB compared to glass similar in type or thickness and above all to ensure uniform performance across a broader range of frequencies.

No, it will however reduce the amount of noise that both enters and leaves your home by approximately 3-4dB over standard double-glazing, which is an audible difference. The noise reduction gained will be dependent upon the quality of your window frames and the type and level of noise you are trying to cut out.
