It features a reinforced aluminum frame adjustable from 23.5 to 43 inches vertically, ensuring a tight and secure fit without drilling. The installation involves measuring the window height after the AC unit or saddle is installed, attaching two plexiglass panels with screws, and sealing with foam insulation. This design keeps the view intact and allows natural light while optimizing cooling efficiency by preventing air leaks around the unit.

Designed for horizontal sliding windows, the Loviga Window Vent Kit measures 10×40 to 64 inches and adjusts to fit most portable air conditioners and dryers. Its standout feature is a drawstring sealing fabric that fits exhaust hoses ranging from 1 to 6 inches, replacing old zipper designs for a true zero-gap seal. The waterproof TU fabric with heat-insulating whitening reflects sunlight, enhancing cooling speed and energy savings. Double-stitched threads and enhanced adhesion contribute to durability and a straightforward installation process.

Its modular design allows use of 2 to 4 panel combinations depending on the window size, ideal for home or office applications.
HOOMEE 400CM Universal Window Seal for Portable AC
The HOOMEE window seal blocks hot air from returning into the room by securely locking the exhaust hose between your horizontal sliding window frame and the glass.

This reduces cool air loss and stops warm air intrusion, enhancing cooling efficiency and energy savings especially for high-capacity units.
Buying Guide for Horizontal Casement Window Air Conditioner Kits
Selecting the best air conditioner window kit for a horizontal casement window involves considering several critical factors to ensure efficient cooling and durability.
Window Compatibility
Verify if the kit fits the specific window type—be it horizontal sliding, casement, or crank-out. Universal kits accommodate multiple styles, but it’s essential to confirm the maximum window dimensions and opening styles to avoid installation issues.
Material Durability
Look for materials like reinforced aluminum, PVC, or high-quality nylon that resist aging, weather damage, and mechanical wear. Waterproof and heat-reflective coatings improve longevity and reduce temperature ingress.
Sealing Efficiency
A tight seal is crucial to prevent warm air from entering and cold air from escaping. Drawstring, zipper, or adhesive fasteners offer varying sealing capabilities. Kits that provide adjustable couplers or flexible zipper designs improve hose alignment and airtightness.
Installation Ease
Choose a kit that offers tool-free or minimal tool installation with clear instructions. Kits that don’t require drilling reduce the risk of window damage and simplify removal during off-seasons.
Adjustability and Fit
Length and height adjustability allow the kit to fit different window sizes and air conditioner models, offering versatility and reusability with different units or windows.
Energy Efficiency Impact
Effective sealing kits improve AC performance, reducing energy consumption and lowering cooling costs. Look for designs proven to block hot air entry and minimize heat leakage.
