It prevents hot air seepage and debris, ensuring portable ACs operate at peak efficiency all summer, whether for overnight sleep or daytime work.

Upgraded Heat-Resistant Adhesive + Heavy-Duty & Tool-Free Installation: Designed for apartments, rentals, dorms and family homes. It has extra-wide industrial Velcro with heat-resistant backing (no sun melting). Engineered to support the 3-layer panel, it bonds firmly to window frames even in heatwaves.
