Custom Size 12ft x 22ft x 25.1ft Waterproof Turquoise Triangle Shade

In this review the focus is on a large, custom-size triangle shade that aims to provide heavy-duty sun and rain protection for patios, carports and yards; the single biggest reason to buy is its waterproof polyester with a PU coating that blocks water and reduces heat while also offering significant UV protection. The reviewer found it best for homeowners who need an economical, removable canopy that can be installed or taken down quickly and that withstands sun and wind without letting water through. It is a practical option when a solid waterproof cover is preferred over a standard mesh sail.

Key Features

• Waterproof material: The polyester fabric with PU coating keeps rain and wind from passing through, making it usable as a temporary carport cover or patio roof during light to moderate rain.
• UV protection: Rated to block up to 90% of harmful UV, the sail helps protect skin and outdoor furniture while lowering direct sun exposure.
• Temperature reduction: The shade lowers ambient temperature by up to 15 degrees beneath the fabric, improving comfort for outdoor seating and play areas.
• Reinforced edges and corners: Dual-layer white webbing and curved edge finishing add strength where the stainless steel D rings attach, helping resist tearing under tension.
• Quick setup and removal: The sail can be pulled up or taken down in roughly five minutes, which suits seasonal use or temporary installations.
• Limited warranty: A 3 year limited warranty provides some protection against material or workmanship issues.

Who It's For

The product is best for homeowners and renters who want a robust, waterproof shade for a patio, carport or backyard seating area and who value quick installation and reinforced hardware. It suits people in sunny climates who need strong UV blockage and a measurable drop in temperature under the canopy.

It is less suitable for those seeking an ultra-large permanent structure or a fully windproof architectural canopy for extreme weather; customers expecting exact commercial-grade structural performance in high-wind storms should consider fixed roofing or professional installations instead.
