Custom Size 11 ft x 21 ft Turquoise Rectangle Shade Sail - 95% UV

Our review finds the Custom Size 11 ft x 21 ft Turquoise Rectangle Shade Sail is a practical choice for homeowners and small businesses who need reliable sun protection without a permanent structure. In this review the single biggest reason to buy is clear: the sail blocks up to 95% of UV rays while cutting ambient temperature by up to 15 degrees, making it especially useful over patios, play areas, or outdoor seating where sun exposure and heat are the main concerns.

Key Features

• 95% UV protection: Crafted from 200 GSM HDPE material, the sail blocks a high proportion of harmful UV and reduces direct sun exposure for people and furnishings beneath it.
• Temperature reduction: The canopy lowers temperatures by as much as 15 degrees compared with unshaded areas, improving comfort during hot afternoons.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-Rings increase longevity and resistance to tearing in windy conditions.
• Custom sizing: The product is made to order using D-ring to D-ring measurements so the sail can match irregular spaces and provide a tailored fit.
• Permeable design: Water and air permeability reduce flapping and ponding while allowing some airflow to further moderate heat under the sail.
• Simple installation: Can be attached to trees, walls, roofs or posts; recommended corner spacing guidance helps achieve proper tension and performance.

Who It's For

This shade sail suits homeowners, small cafes, daycare centers and gardeners who need a flexible, removable canopy that delivers commercial standard durability without investing in fixed construction. It is a good fit where sun protection and cooling are priorities and where mounting points such as trees, poles or building walls are available.

People who need a permanent, fully waterproof awning, or who lack secure anchor points, should look elsewhere; the sail is water permeable and requires appropriate tensioning and hardware to perform well in very exposed locations.
