Product description
Aozzy Portable Air Conditioner Window Seal Kit for Sliding/Hung Window
Stop Wasting Electricity. Keep Your Cool Air Inside.
Silver-Coated Portable AC Window Seal Kit – 100% Airtight, Thermal Insulation, Maximize Cooling Efficiency
Particularly suitable for sliding doors, sliding windows and single-hung windows, it is the ideal solution for replacing expensive plastic panels or flimsy transparent sealing strips.
Why Choose US? Our Solution – Ultra-Thick Silver Coating
We solved both the light and heat problem with one material: ultra-thick silver coating laminated onto premium Oxford fabric.
- 100% Blackout – Zero light transmission. Close your curtains , your room becomes completely dark, even at noon.
- UV Protection – Blocks harmful UV rays, protecting your skin and furniture from fading.
- Privacy Upgrade – No one can see inside. Your home, your sanctuary.
- Reflective Heat Barrier – The silver layer bounces sunlight back outside, keeping the seal itself cool and reducing heat gain.
The result? A room that’s dark, private, and noticeably cooler – without wasting electricity
No Zipper, No Leak – Built‑in Dual‑Sided Hose Sleeve
Forget flimsy zippers that break and leak. Our seal comes with a built‑in dual‑sided hose sleeve – simply insert your exhaust hose (fits 5”‑6” diameter) and tighten the drawstring. Creates a “zero‑gap” seal around the hose, preventing hot air backflow and stopping rain and dust from entering. The two sleeves can be separated – one on the inside, one on the outside – to distribute weight, reduce pulling, and improve the sealing performance.
Get the Perfect Fit – Three Heights Available
we offer this seal in three different heights. We strongly recommend measuring your window height accurately before ordering.
Between two sizes? Choose the larger one.
Too small leaves a gap you can’t fix. Too large? Just fold the extra fabric inward and secure with loop tape – perfect fit in seconds. Always measure your window height first, then pick the size that matches or is slightly larger. Fold to fit.
