Portable Air Conditioning Wall Vent

[simps100]

Hi all

Am looking at something like this: http://www.dry-it-out.com/125mm-x-1m-kit-with-gravity-outlet

for our portable AC units which would be a much better solution than out be window - has anyone installed anything similar - only question I’ve got is what to use to cap it off over winter when not In use?

Thanks

Marc

Has gravity flap which prevents back draft all year round, you could also shove a bag full of screwed up paper in it during winter.
