External Insulation - vents fitted in Each room

[suicra05]

Hi,

We just got our house externally wrapped. Each room has now 100mm vents. Some of the vents are fixed and others you can close with a slider.
The issue is there is now noise coming through the vents. Could anyone recommend anything to put into the vents to reduce and muffle the outside noise.

not a recommendation, just a reference point:

You will lose a lot of heat if these are just the old style standard vents. There are some great single room heat recovery units you could install that would filter the air, retain the heat and reduce the noise.
