Custom Size 15ft x 20ft Green Rectangle Sun Shade Sail - Heavy Duty

Our review of this custom size 15' x 20' green rectangle sun shade sail finds it well suited for homeowners and small businesses who need dependable sun protection and a tailored fit. The single biggest reason to buy is its combination of heavy-duty 200 GSM HDPE construction and measured customization from D-ring to D-ring, which delivers reliable 95% sun protection and a cooler outdoor area without sacrificing airflow. Installation is straightforward for a typical DIYer and the material and reinforced edges mean it stands up to regular outdoor use.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays so shaded areas are safer for extended outdoor use.
• Temperature reduction: The sail can lower ambient temperatures by up to 15 degrees compared to unshaded spots, making patios and play areas noticeably cooler.
• Custom fit: Precise measurement from D-ring to D-ring allows a tailored installation so the sail fits the exact area you need covered.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching increase longevity and prevent fraying under normal use.
• Breathable and water permeable: The fabric is air and water permeable, reducing wind load and letting light rain pass through rather than pooling.
• Easy installation guidance: Clear recommendations on corner gaps and attachment points help achieve a secure, tensioned fit.

Who It's For

This shade sail is ideal for homeowners with patios, decks, pools or play areas who want strong sun protection and a custom-sized canopy made to fit specific anchor points. It also suits small commercial outdoor seating and market stalls where durability and UV performance matter.

It is less appropriate for buyers seeking a fully waterproof awning or a permanent rigid canopy; those users should consider hard-structure solutions. People who cannot take basic measurements or do simple rigging may prefer professional installation services.

Frequently Asked Questions

Is the fabric waterproof?
The fabric is water permeable so it sheds light rain and prevents pooling but is not a fully waterproof, rigid canopy for heavy storms.

How durable are the attachment points?
Stainless steel D-rings and reinforced double-layer stitching provide strong, long-lasting attachment points suitable for regular outdoor conditions.
