What Stands Out
Versatile Insulation
These panels provide year-round insulation, preventing heat and cold from entering your home, ensuring energy efficiency in both summer and winter seasons.
Durable Construction
Made from robust materials, these side panels are designed to withstand outdoor elements, ensuring long-lasting performance and reliability for your window air conditioning unit.
Easy Installation
With a straightforward design, these panels can be quickly installed without professional help, allowing users to enhance their home comfort in no time.
Product Details
- UNIVERSAL DESIGN: The air conditioner side insulation panel can cover damaged original insulation panels or be used as a replacement, suitable for most window air conditioners with 5,000 - 22,000 BTU
- HOME COMFORT MAINTENANCE: Similar to window weatherstripping, it effectively blocks dust, pollen, insects, heat, and airflow. The high-density foam material helps reduce noise and vibration, keeping your home comfortable
- ENERGY SAVING:Helps seal gaps between the air conditioner unit and window frame. Blocks cold air from entering in winter and hot air in summer, reducing heating and cooling costs
- EASY INSTALLATION: Can be applied over damaged original panels or directly replace the original panels
- PACKAGE INCLUDES: 1 pair of self-adhesive side channels, 2 foam panels, Dimensions: 17 in (H) × 9 in (W) × 1 in (D)
