Seal the cool, shut out the heat.
An ideal solution for using portable air conditioners in rooms with large glass doors, allowing fast installation of the exhaust hose without losing valuable cooling. Designed to keep cool air inside where it belongs. Made from durable fabric with an integrated zip system, the seal creates an airtight barrier that limits warm air from entering the room. Installation is simple and drill-free, with no permanent changes to your door structure.
Reusable and compatible with most standard balcony doors, this practical accessory improves cooling comfort while helping reduce running costs — a smart upgrade for everyday efficiency.
