Key benefits Effective UV protection: blocks harmful UV rays to reduce sun exposure for passengers, especially children. Reduces interior heat: heat‑insulating structure and coating lower cabin temperature and limit heat buildup. Preserves window function: mounts to the vehicle body without restricting window movement, so you can still open windows for fresh air. Flexible installation: retractable and foldable design lets you deploy or stow the sunshade quickly; included hooks and suction cups provide secure attachment. Main features Function: Retractable front sunshade and window curtain that provides sun and UV protection for the windshield and side windows. Mounting: Attaches directly to the car body; installation does not impede normal window operation. Design: Foldable and retractable for compact storage; usable as a windshield sun visor or side curtain. Hardware and finish: High‑hardness alloy frame combined with a heat‑insulating coating to block radiation and improve cooling performance. Accessories: Comes with hooks and suction cups for straightforward attachment to the vehicle. How it solves problems Prevents interior overheating on sunny days, reducing the need for immediate air conditioning and protecting interior surfaces. Lowers UV exposure for passengers, helping protect children's sensitive skin and eyes during drives. Lets you maintain ventilation—windows can still open when the shade is fitted, so you do not have to sacrifice fresh air for sun protection. Performance and compatibility notes Designed for front windshield and side window installation; the retractable and foldable form factor adapts to typical vehicle openings. Robust alloy frame and insulated coating provide long‑lasting sun and heat resistance without adding bulk. Secure attachment via hooks and suction cups keeps the shade stable while parked or during slow movement. Typical use scenarios Parked car on a hot day: deploy the retractable windshield shade to keep the cabin cooler and protect the dashboard and electronics from sun damage. Family trips with children: install the side curtain to shield rear-seat passengers from direct sunlight while still allowing windows to open for ventilation. Quick errands or waiting at pickup/drop-off: use the foldable sunshade for fast protection when you step away from the vehicle. What you get Retractable, foldable sunshade for windshield and side windows High‑hardness alloy frame with heat‑insulating coating Hooks and suction cups for mounting Practical tips Ensure surfaces are clean before attaching suction cups for best hold. Retract and store the shade when not in use to avoid wind wear and to maximize interior visibility. For maximum cooling effect, deploy the shade before the cabin temperature rises. This sunshade offers a practical way to reduce heat and UV exposure while preserving window functionality and ventilation.
