Unbranded Window Air Conditioner Insulated Foam Panels Seal Kit for Cold Hot Air Leak Prevention Winter Summer

Air sealing protection helps reduce hot and cold air gaps around window air conditioner units. These insulated foam panels are made with EVA foam and an aluminum foil facing to support heat reflection, moisture resistance, dust blocking, and noise reduction. The cut-to-fit design works with window AC units from 5000 to 22000 BTU. Measure the side opening, trim the foam block to size, and place it around the AC frame for a closer seal. The panel helps keep cool air indoors in summer and helps reduce cold drafts in winter. Suitable for bedrooms, living rooms, apartments, offices, and workshops using window-mounted air conditioners. The lightweight 8.4 oz structure is easy to handle, remove, and store after seasonal use. Includes a 30-day warranty.
