Product description Key benefits Effective sun protection: The outdoor awning is made from HDPE (high-density polyethylene) fabric that blocks up to 90% of harmful UV rays, helping protect skin and outdoor furniture. Flexible shade control: The U-shaped, wave-style canopy with movable wires lets you open or close individual shade panels to exactly control how much sun or shade you want. Comfortable outdoor living: Designed for family use, the fabric and design create a comfortable, shaded outdoor area so you can enjoy your porch, patio, or balcony without direct sun exposure. Main features Material: HDPE high-density polyethylene shade fabric — suitable for outdoor use and designed for sun protection. Design: U-shaped wave sun-sail layout with sliding/movable wires that allow sections to retract or extend independently. Function: Retractable pergola-style operation — adjust the number of open shade sails to change shade coverage and air flow. Size note: Listed size is Width x Length. If you prefer a more pronounced U-shaped wave effect, choose a size slightly longer than the actual measured length. How it solves problems Reduces heat and glare so outdoor spaces are usable during sunny hours. Provides privacy and shaded shelter without a permanent roof installation. Allows quick adjustment of shade coverage to match changing sun angles or activities. Compatibility and installation guidance Intended for outdoor structures where a retractable shade is useful: attach to a pergola frame, gazebo, veranda, balcony railing, or between posts. Check the listed Width x Length before ordering. For a deeper U-wave appearance, select a slightly greater length than your measured span. The movable wire system gives compatibility with frames or support points that allow attachment and sliding of the wires. Typical use scenarios Family patio lunches: Lower the shade panels during midday to keep the dining area cool and shielded from UV while still allowing airflow. Balcony or deck relaxation: Create a private, shaded retreat that you can open partially for sunlight or close for full shade. Garden or gazebo coverage: Use the retractable U-wave canopy over a gazebo or pergola to control sun exposure during parties, naps, or outdoor work. What makes it stand out High-density HDPE fabric that blocks up to 90% of UV rays. Wave-shaped, retractable design with movable wires for precise shade control. Versatile application for porches, gazebos, terraces, decks, balconies and backyards.
