More Airtight & Efficient
Why Choose our？
Unlike the plastic panels that come with most portable AC units — or those thin, translucent fabric seals — our product solves the real problems.
- Plastic kits are hard to install, seal poorly, and often don't fit your exhaust hose size. You end up wasting time trying to match the compatibility.
- As for common white fabric seals: they're too thin, let light through, and offer little heat insulation. Zipper versions are even worse — they leak air, letting hot air flow right back into your room.
- We have improved on all these issues. Our upgraded seal delivers easy installation, 3-layer reinforced material superior airtightness, and excellent heat insulation — keeping hot air out and cool air in with zero air leakage.
Either Side Can Be Used as Desired
You can choose either side as the outward-facing layer, and the airtight performance stays the same.（NOTE:Due to the special material of the silver-coated aluminum film layer, when choosing which side to apply custom adhesive (Adhesive Loop Velcro), if you decide to attach the Velcro to the aluminum film side, please measure the dimensions carefully. Otherwise, peeling off the Velcro will damage the aluminum film layer.）

- Silver reflective coating
- Insulated with cotton batting
