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.
