【3-Layer Thickened 100% Thermal Insulation Kit】 Brand new on the market: triple-layer thickened portable ac door vent kit — our ac door seal kit features a 3-layer composite structure (aluminum film + thickened cotton + high-density Oxford fabric) delivering 100% airtight thermal insulation, UV protection, upgraded privacy, and blocks harsh light — your room stays soft, quiet, and comfortable. Installs in seconds. The heavy-duty material locks cold air inside, keeps out rain, dust, and debris.It is the best replacement for expensive plastic panels and thin, flimsy seals.

【Say Goodbye to Traditional Transparent Door Seals】 Still dealing with ordinary seals that are thin, let in light, leak air, and offer weak insulation? Traditional flimsy materials and poor fit can't block harsh sunlight, causing rapid loss of indoor cool air. Our door seal features a new 3-layer thickened composite — solid and heavy-duty construction, leaving thin single-layer seals behind. It flexibly seals window and door gaps for an airtight fit, blocks outdoor heat waves, locks in every bit of cold air, and completely stops both cold leakage and hot backflow — giving you a comfortable, worry-free home all summer long.

【Flexible Size Adjustment】 This portable air conditioner door kit is 98inch, with loop fabric stitched neatly and strongly on both sides around all four edges — a thoughtful design that makes installation quick and easy. If your window height is exactly or slightly less than 98inch, it fits perfectly. For smaller windows, simply fold the kit inward to the desired height and secure it with the included loop fabric strip. Completely solves the hassle of poor sealing caused by even slight height deviations.

【Dual-Layer Exhaust Sleeve】 Still dealing with traditional zipper-style vents that easily burst, fall apart, and leak cold air? To solve these pain points, our door vent kit features a brand new dual-layer vent design — say goodbye to failing zippers for good. The dual-layer structure locks cold air inside and keeps it from escaping. Better yet, the two sleeves can be separated: install one inside the window and the other outside. This distributes the weight, prevents pulling and deformation, and delivers a more stable, reliable seal — eliminating all sealing issues at the source.

【Easy 3-Step Installation & Convenient Storage】 1.Apply hook-side tape around your door frame.2.Fold kit inward to fit height, secure with included loop-side tape.3.Thread hose through vent opening and tighten drawstring. No tools needed, fast. Unlike expensive, heavy plastic panels, our air conditioner door kit is lightweight Oxford fabric. Rolls up for storage, takes almost no space.

New drawstring structure design allows the sealing fabric to better fit the 5.9" diameter exhaust, no additional accessories required, achieving 100% sealing effect of true "0" gap, firmly locking the cool air inside while also blocking out heat flows, rain, mosquitoes bugs etc. In addition, we also keep a section of the zipper opening to meet your needs for different size exhausts and multiple exhausts at the same time.
