Cool Area Sun Shade Sail 20x20 ft Rectangle - Durable UV Shade

In this review of the Cool Area Sun Shade Sail 20x20 ft rectangle, the bottom line is simple: this is a straightforward, budget-friendly way to add serious sun protection for patios, decks, pools and gardens. The biggest reason to buy is the fabric and construction: a single-piece high density HDPE panel with reinforced stitched seams and stainless steel D-rings delivers reliable shading and easy attachment. Installers should allow 0.5-1 ft of extra space for mounting hardware and expect fabric elasticity to create a tolerance of about 4 in.

Key Features

• Single-piece construction: a whole shade fabric without splicing seams gives cleaner appearance and better shading performance than stitched panels.
• High density HDPE fabric: 100% new HDPE provides up to 95% UV protection and an 85%-90% shading rate to reduce sun exposure.
• Reinforced edges: stitched seams around all edges prevent fraying and help the sail hold its shape under tension.
• Stainless steel D-rings: rust proof D-rings at each corner make attachment to posts, houses or fences straightforward and corrosion resistant.
• Flexible sizing tolerance: the fabric has elasticity and a 4 in tolerance, so plan for 0.5-1 ft extra per side for accessories during installation.

Who It's For

The Cool Area 20x20 ft rectangle shade sail is best for homeowners and renters looking for an affordable, attractive shade solution for outdoor living areas such as patios, pergolas, pools and carports. It works well for DIY installers who can anchor the corners to sturdy posts, fences or building fixtures and who appreciate a whole-piece fabric without visible splices.

Those who need a permanent, heavy-duty storm-rated canopy or a precisely measured nonstretch fabric may want to consider other commercial-grade options, since the HDPE material is designed for sun and general outdoor use and includes a natural elasticity and size tolerance.

Our Verdict
