Double-Layer Aluminum Foil Thermal Insulation : Constructed with double-sided high-reflective aluminum foil and thickened high-density pearl cotton interlayer, this multi-layer heat insulation structure effectively blocks the transfer of hot and cold radiation. In hot summer, it reflects direct solar thermal radiation from outside the window to prevent high temperature from entering the room and relieve indoor stuffiness. In cold winter, it retains indoor warm air, reduces heat loss through window glass and gaps, and slows down temperature drop, maintaining a stable and balanced indoor temperature all year round. UV Blocking Performance : The reflective aluminum foil layer blocks up to 99% harmful UV rays and harsh direct sunlight. It prevents fading and aging of sofas, carpets, furniture and wooden floors caused by long-term sun exposure, reduces skin irritation from UV radiation, and cuts harsh glare for soft and comfortable indoor lighting. Ideal for sunlit bedrooms, sunrooms and balcony windows. Privacy Protection : The dense aluminum foil material is completely opaque to deliver full blackout performance. Outsiders cannot see the interior during daytime, and indoor scenes won’t be visible from outside even when the lights are on at night. It combines blackout sleep function and household privacy protection, suitable for various spaces to create a quiet dark resting environment. Easy Installation & Reusable Design : Comes with reinforced suction cups for residue-free mounting without scratching glass or window frames. It fits windows, sliding doors and garage windows of all sizes. Foldable for space-saving storage, it can be reused for all seasons and re-installed after moving or replacing windows. Quick to put up and take down; simply wipe the aluminum foil surface with a damp cloth for easy cleaning. Wide Application Scenarios : Built with thick multi-layer EPE pearl cotton interlayer and waterproof, sun-resistant aluminum foil surface, it slightly weakens ambient noise from traffic and streets. The flexible tear-resistant material is waterproof and durable against aging. Perfect for home bedrooms, offices, sunrooms, RVs, campers, garage light windows and more occasions., Manufacturer: xifangbaihuojingxiaobu
