All windows
from NorDan have excellent sound reducing qualities and, by
incorporating special glass, can create even better noise
reduction.
Defeating noise pollution
In extreme cases, where people live or work in very noisy environments,
NorDan offers solutions to provide a dramatic improvement to their
quality of life. The optimum NorDan solution offers a sound
reduction of 48dB(A) and is achieved by cleverly coupling two windows
together to act as one. The outside window is outward opening and
the inner window is inward opening. This allows access to all sides
of the glass for cleaning and maintenance. Data is available on a large
variety of acoustic tests. Please ask for details.
Note: All NorDan's acoustic tests are
based on the whole window performance, not just the glass. After all,
there is no point using highly efficient glazing for a specific purpose
if the sash and frame do not complement the glazing with a positive
seal against all intrusions, whether from noise, weather or burglars.
