Having recently moved into a new build apartment, the noise through the
trickle vents in the bedroom window is driving me mad. Ironically, the
spare bedroom (which faces a railway line) has acoustic vents through
the wall rather than trickle vents through the window frames and it is
*much* quieter than the master bed where the trickle vents (even when
closed) let in way too much noise from the nearby road and passers by.
I have been trying to find some sort of acoustic trickle vent to
replace them with but thus far have only found the DN range from
Greenwood
(

unfortunately doesn't come in the size I need.
Can anyone suggest any others?
thanks,
David
