VELFAC SOUND - Noise reduction

Efficient glazing is fundamental to noise control. Glazing is effective at reducing external noise, but the use of thicker glass or different combinations of glass improves performance.

A standard VELFAC 200 double-glazed unit achieves Rw32, which can be increased to Rw39 by adjusting the thickness of the glass and the glazing rebate.

A standard VELFAC 200 ENERGY triple-glazed unit achieves Rw33, which can be increased to Rw43.

Please call VELFAC for solutions to your specific noise reduction requirements.


Please find more information about sound reduction with the VELFAC 200 DGU window system under Performance.
