It sounds like you're referring to "air sealing." Air sealing is a process used to reduce the amount of air that leaks in and out of a building. This is typically done to improve energy efficiency, enhance comfort, and lower utility bills. Common places where air sealing is applied include windows, doors, ducts, and other gaps or cracks in a building's envelope.

an Air Seal, also known as an inflatable air gasket or pneumatic seal, often used in isolators for cleanrooms, containment, or sterile processing. These are designed to inflate to create a tight seal and deflate to release—ideal for things like:

• Glove box isolators

• Transfer hatches / RTP ports

• Cleanroom doors or panels

• Sterile filling lines
