I have been looking for an alternative to cheap, unsightly, unattractive, messy, taped-on strapped-on destructive plastic garbage bag type objects attached to our building for years.
"I COULDN'T FIND ONE", so I decided to manufacture them!

Where is "BreezeBlocker" needed?
Anywhere that has through the wall air conditioners with sleeves protruding from the exterior of the building 2" or more!

Works exceptionally well when undersized replacement units (or no units at all) are installed into existing sleeves that cause large gaps.
