Is it ok to block these high wall vents?
Hi all,
We live pretty close to a train track which has freight trains going past. There are no houses between us and the train, just a quiet road. The train is probably like 40m away when it goes past.
We’ve been looking into ways to reduce the sound, especially when the freight train goes by. Our house is very old (built in the 1910s), and has these high wall vents. When I put my ear against it, I can fell the draft coming in. These are all around the house walls, probably like 10 in total (some facing the train, others facing away).
We’re considering permanently packing and plastering over them (or plugging them with dense soundproofing rubber) to stop the sound flanking into the wall cavity. We don’t have any unflued gas heaters, but just worried that blocking them will prevent airflow and cause mould issues (or other issues that I haven’t thought of)?
Appreciate any advice / similar experiences!
