Breeze Stop Surround Insulation Side Panels for Window AC
The Breeze Stop Surround Insulation Side Panels offer a 1-inch thick insulating foam core covered in flexible white vinyl, designed to enhance window air conditioner efficiency during both winter and summer. These panels fit window sizes up to 36 inches wide but require cutting to size using scissors. They are intended to cover existing pull-out plastic sides rather than replace them, providing extra insulation against drafts, dust, and temperature extremes. The vinyl cover ensures durability and a clean, aesthetic finish suitable for indoor use.
Yotache 1″x1″ Air Conditioner Window Seal Foam Strips
Yotache’s Air Conditioner Seal Kit includes two rolls of 1” by 1” soft, open-cell foam made from NBR and PVC materials. This non-adhesive foam strip resists weather, flame, and extreme temperatures ranging from -40℃ to 90℃. It is easy to place between the AC unit and window for an effective seal that reduces air leaks, dust, and noise. This foam doesn’t require glue, allowing you to reposition it easily. This solution supports all-season protection and noise reduction.
SZZSAF Window AC Side Insulated Panels with EVA Foam
The SZZSAF Side Insulated Panels are crafted from EVA foam, boasting a smoother surface and durable construction for enhanced appearance and longevity. These panels help isolate heat, dust, and pollen, improving your indoor comfort while aiding energy efficiency year-round. Designed for 5000-12000 BTU window units, they fit window frames up to 39 inches wide. Installation is user-friendly with scissors for cutting, and double-sided nano tape or tape for custom mounting.
LBG Products Window AC Foam Insulation Panels Kit
LBG Products offers a universal design insulation panel kit comprising two foam pieces (17x9x7/8 inches) that fit most window air conditioners from 5000 to 22000 BTU. These panels act as effective window seals, preventing dust, pollen, insect intrusion, drafts, and noise transmission. By insulating the gap between the AC and window frame, they help maintain consistent indoor temperatures, reducing strain on heating and cooling systems.
GCGOODS Foam Insulated Panels with Top Seal Strip for AC
The GCGOODS Insulated Foam Panels feature a white, sleek PU leather surface over foam insulation designed to eliminate drafts, heat transfer, moisture, and light infiltration around window AC units. The kit includes a 39” by 1.5” top foam seal strip that works alongside side panels to provide comprehensive insulation surrounding the window unit, enhancing comfort in hot summers and cold winters. This foam panel is ideal for users looking to upgrade their existing plastic side covers with a more effective insulation solution.
Buying Guide: Choosing the Right Air Conditioner Insulation Foam
To make the best choice in air conditioner insulation foam, consider these key factors:
- Material Quality: EVA foam, open-cell NBR+PVC foam, and vinyl-covered foam are common materials offering various levels of durability, weather resistance, and insulation. EVA provides durability and smooth finish, while NBR+PVC offers excellent weather and flame resistance.
- Thickness and Coverage: Thicker foam panels (around 1 inch) typically provide better insulation. Also, check panel dimensions relative to your window and AC unit size for proper coverage.
- Fit and Compatibility: Measure your window size and AC model BTU. Some panels fit universal sizes (e.g., 5000-22000 BTU units), while others require cutting or trimming to size. Consider kits that cover side gaps and also include top seal strips for full surround protection.
- Installation Ease: Look for foam panels that are easy to cut and attach with included tapes or adhesive strips. Non-adhesive foam tapes offer repositioning flexibility but may require additional securing methods.
- Additional Benefits: Some foams reduce noise and vibrations, prevent insect entry, and protect from dust and pollen, further enhancing indoor comfort.
Evaluating your specific window air conditioner setup, climate, and insulation needs will help you select the best foam insulation product that improves energy efficiency and home comfort year-round.
