These panels block outdoor air, insects, and moisture from entering around the unit, helping the AC maintain its set temperature without working harder than needed. Each panel measures 9 inches wide by 18 inches tall by 0.875 inches thick. Self-stick side channels are included, allowing the panels to be secured to the window frame without additional hardware. This kit is a direct replacement for worn, torn, or missing factory foam accordion panels typically found on indoor window AC installations.\u003c\/p\u003e\n\u003cp\u003eThis product is suited for residential window air conditioner installations where the original foam side accordion panels have deteriorated or are no longer sealing properly. The panels fill the open space between the extended AC chassis and the window frame. They are commonly installed during seasonal AC setup by homeowners, maintenance technicians, or property managers servicing window units in apartments, offices, and single-family homes. The included self-stick channels simplify reinstallation without requiring professional tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSold as a pair — covers both sides of a standard window AC unit\u003c\/li\u003e\n  \u003cli\u003eThick foam construction provides a firm seal against drafts, insects, and moisture\u003c\/li\u003e\n  \u003cli\u003ePanel dimensions: 9 inches x 18 inches x 0.875 inches per panel\u003c\/li\u003e\n  \u003cli\u003eSelf-stick side channels included for tool-free attachment to window frame\u003c\/li\u003e\n  \u003cli\u003eDesigned as a drop-in replacement for factory-installed accordion foam side panels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for indoor window-mounted room air conditioner foam side panels where the opening requires panels approximately 9 inches wide by 18 inches tall.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation does not require electrical trade certification but should be performed with the air conditioner unplugged or powered down at the outlet. Clean and dry the window frame channels before applying the self-stick backing to ensure a lasting bond. Verify the panel dimensions match the gap on each side of the installed unit before trimming or fitting. Do not force panels into undersized openings, as compression beyond the designed thickness may compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePanel Width\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePanel Height\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePanel Thickness\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Foam\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Contents\u003c\/strong\u003e: 1 pair (2 panels) with self-stick side channels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6 pairs per case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: THERMWELL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AC14H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FROST KING","offers":[{"title":"Default Title","offer_id":51559042941234,"sku":"AC14H","price":96.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a18db06afa2153496ede19417507bc1a.jpg?v=1786426672","url":"https:\/\/voomisupply.com\/products\/thermwell-ac14h-foam-ac-side-panel-9x18-replacement-pair","provider":"Voomi Supply","version":"1.0","type":"link"}
