- Ultimate 3-Layer Thermal Shield & Heat Reflection: Our professional-grade 3-layer insulated material, made of reflective aluminum foil, high-density cotton core and waterproof Oxford fabric, forms a robust thermal barrier. Perfect for living rooms, bedrooms and home offices in scorching summer, it blocks 100% sunlight, reflects outdoor heat (unlike thin single-layer seals), keeps rooms cool, reduces energy bills, and serves as a reliable indoor temperature control solution for work, family relaxation and night sleep.
- Stepless DIY Adjustment & Custom Precision Fit: Say goodbye to pre-set 10cm gaps—ideal for renters, homeowners and those with non-standard window sizes. Its innovative fold-to-fit design supports stepless height adjustment, allowing precise customization for sliding windows/doors. Suitable for standard bedroom windows, living room sliding doors and oversized 90" patio glass doors, it ensures flawless, gap-free installation, outperforms rigid plastic plates, and meets diverse house type needs.
- Zero-Leakage Drawstring Sleeve & Air-Tight Seal: Perfect for those using portable AC in bedrooms, dorm rooms and home offices, it solves cooling loss issues of traditional plastic kits. The specialized integrated hose sleeve has a heavy-duty adjustable drawstring, tightly wrapping the exhaust hose for an air-tight seal. It prevents hot air seepage and debris, ensuring portable ACs operate at peak efficiency all summer, whether for overnight sleep or daytime work.
- Upgraded Heat-Resistant Adhesive + Heavy-Duty & Tool-Free Installation: Designed for apartments, rentals, dorms and family homes. It has extra-wide industrial Velcro with heat-resistant backing (no sun melting). Engineered to support the 3-layer panel, it bonds firmly to window frames even in heatwaves. Ultrasonic quilting prevents insulation shifting; tear-resistant Oxford ensures durability. Tool-free hook-and-loop installation is renter-friendly (no drilling/marks) for quick bedroom, office setup.
- Universal Compatibility + Reversible Design + 100% Blackout Privacy: Suitable for renters, homeowners, students and remote workers. It fits all 6-inch (including 5" and 5.9") portable AC exhaust hoses, no extra adapters/tools needed, compatible with Midea, Hisense, LG and other mainstream brands. Reversible design offers silver heat-reflective (sun-facing windows) and grey Oxford (decor-matching) sides; 100% blackout is ideal for bedroom sleep and office screen glare reduction.
