IMPROVING SOUND REDUCTION WITH VELFAC WINDOWS
Efficient glazing is fundamental to insulation and noise control
The noise level within most room of a family house should not exeed 30db. If for example loud traffic noise amounts to 65-70Db, the building must be able to reduce the noise level by 35-40Db.
VELFAC glazings are designed to reduce the level of unwanted noise including heavy traffic.
Our high performance windows and doors offer excellent insulation which not only reduces heating bills, but also provides impressive noise reduction.
Sound dampening performance in windows is shown by an Rw rating which indicates the number of decibels by which a window can reduce apparent noise. A standard VELFAC double glazed unit achieves Rw32, which can be increased to Rw41 by adjusting the thickness of the glass and the glazing rebate.
While VELFAC standard double glazing is very effective at reducing external noise, the use of thicker glass or different combinations of glass can significantly improve performance and can deliver more precise acoustic control.
