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
Can anyone suggest any others?
thanks,
David
