Portable AC Window Foam Insulation Panels – Set of 3
Keep the Cool In & the Heat Out
Stay comfortable all summer long with this Portable AC Window Vent Insulation Kit — a set of 3 adjustable foam panels designed to seal gaps around portable air conditioner hoses, sliding windows, and vents. Made from high-strength foam with an easy adhesive backing, this kit creates a tight thermal barrier that helps your AC run more efficiently, lowers energy consumption, and keeps unwanted outdoor air, dust, and ambient noise from creeping inside.
Key Features
- Thermal Barrier: Maintains a consistent indoor temperature by blocking hot air entry and preventing cool air from escaping — helping your portable AC work smarter, not harder.
- Noise-Dampening Seal: The reinforced foam sealing structure reduces the transfer of ambient outdoor noise for a quieter, more comfortable space.
- Wide Compatibility: Adjustable and trimmable to fit a variety of window openings — works seamlessly with virtually any portable AC setup, horizontal or vertical.
- Durable High-Strength Foam: Resistant to deformation and wear so the panels hold their shape season after season, providing long-lasting thermal insulation.
- Flexible Assembly: Three 16.5-inch (42 cm) panels can be stitched together to cover wide vents and fill gaps of various widths — no awkward cutting or guessing.
- Tool-Free Installation: No tools, no special skills required. The included adhesive strip makes setup fast, stable, and mess-free.
