How can I improve wall vents in 15 yr old house?

Hi, I live in a 3 bed end of terrace two-storey house - constructed about 15 yrs ago - wall construction is 225 hollow block with dabbed-on polystyrene insulated plasterboard overall wall thickness of 300mm.

Wall vents consisted of hole in wall with galvanised grille outside and closeable white plastic grille inside - i have since fitten 100 pvc pipe and insulatel all round with quilt insulation to stop airflow from passing behind plasterboards and out at skirtings, sockets etc - result has been good.

I now wish to fit new vents t o further improve - ie reduce/control airflow when there is a gale blowing and reduce noise from outside.

Any advice appreciated tks.

Aereco do a unit which will fit existing 100mm wall vents. They have a humidity sensor which when used in kitchens etc they can open/close to suit the conditions. The sensor is nylon and expands/contracts itself so it doesn't need a power supply. Do a search for aereco and you will get info on their website. Heatmerchants stock them at times. You can also add an insert to reduce noise levels.

Vent Axia alos do a single room fan powered heat recovery fan with has an impeller fan which does similtainious supply and exhaust. Its a 100mm dia core which runs on trickle mode with a cord for boost. Could be the job, have specified for renovations.
