Custom Size 16ft x 20ft Red Rectangle Sun Shade Sail - 95% UV

In this review the 16' x 20' red rectangle sun shade sail is judged on fit, durability and sun protection for patios and play areas; it is best for homeowners and small businesses who need a custom-sized, breathable canopy that blocks strong sun. The bottom line: this shade sail delivers reliable 95% sun protection from its 200 GSM HDPE fabric, reduces ambient temperature noticeably, and installs without special tools, making it a sensible choice when a tailored cover is needed.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric blocks up to 95% of harmful rays for safer time outdoors.
• Temperature reduction: The sail lowers shaded air temperatures by up to 15 degrees compared to direct sun, improving comfort on patios or decks.
• Customizable fit: Measured D-ring to D-ring sizing lets buyers order a made-to-measure canopy to suit specific mounting points and shapes.
• Breathable and water permeable: The knitted HDPE allows breezes to pass and reduces wind load while shedding water rather than holding pools.
• Reinforced hardware: Stainless steel D-rings and double stitching at the edges add durability and resist fraying over repeated use.
• Easy installation guidance: The sail can be attached to trees, walls, poles or roofs, and performance improves when corner gaps and tension are set as recommended.

Who It's For

This shade sail is ideal for homeowners with patios, play areas, pools or outdoor seating who want a tailored canopy that both cools and protects from UV. It fits well for small commercial spaces like cafe seating or market stalls that need a durable, breathable cover that looks tidy and lasts through variable weather.

It is not the best choice for someone who needs a fully waterproof canopy or a permanently rigid structure; because the product is water and air permeable, heavy continuous rainfall may pass through rather than be shed like a hard awning.

Pros & Cons

Pros

• High UV protection from the 200 GSM HDPE material keeps occupants safer in strong sun.
• Noticeable cooling effect, often reported around a 15 degree drop in shaded areas.
• Durable construction with stainless steel D-rings and reinforced double stitching for longer life.
• Custom sizing and straight-edge options let the sail match specific mounting layouts.

Cons

• Because it is breathable and water permeable, it will not keep all rain out like a solid, waterproof canopy.
• One reported case noted incorrect dimensions, so careful measurement and confirmation with the seller are recommended.
