16ft x 19ft x 24.8ft Right Triangle Sun Shade Sail - 95% UV Block

Our review of this custom size right triangle shade sail finds it best for homeowners and small commercial spaces that need a tailored sun protection solution. The single biggest reason to buy is the fabric performance: made from 200 GSM HDPE it blocks up to 95% of UV and reduces temperature under the canopy by up to 15 degrees, which makes it noticeably cooler than unshaded areas. The supplied stainless steel D-rings, reinforced edges and double stitching give real confidence in durability for season-long use.

Key Features

• 95% UV protection: The 200 GSM HDPE fabric blocks up to 95% of harmful rays so shaded areas feel safer for people and pets.
• Temperature reduction: The sail can reduce ambient temperature beneath it by as much as 15 degrees compared with direct sun, offering a cooler spot to relax.
• Custom sizing: Measurements are taken D-ring to D-ring so the sail can be made to fit irregular or precise outdoor layouts.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching resist fraying and hold up under tension.
• Breathable and water permeable: The woven HDPE allows air and some water through to reduce wind load and pooling compared with solid covers.
• Flexible installation: Can be attached to trees, roofs, walls or posts and adjusted by leaving recommended gaps at corner D-rings for best tension.

Who It's For

This shade sail is ideal for patio owners, small cafes, play areas and animal enclosures who need a customized triangular coverage and value strong UV protection. It suits people who can measure D-ring to D-ring and want the flexibility to mount to existing anchors like trees, poles or walls.

It is less suitable for buyers who need a perfectly rigid, waterproof awning or who expect a pre-cut universal size that cannot be customized; customers seeking full waterproof coverage or rigid framing should look elsewhere.

Pros & Cons

Pros

• High UV blockage from 200 GSM HDPE material provides reliable sun protection.
• Construction quality is strong with stainless steel D-rings and reinforced edges for long life.
• Custom sizing allows a tailored fit for unusual areas and precise installations.
• Permeable weave reduces wind load and prevents water pooling compared with solid tarps.

Cons

• Some buyers report the delivered size can feel smaller than expected, so careful measurement is essential.
• Not fully waterproof, so it will not keep heavy rain entirely out beneath the sail.

Frequently Asked Questions

Does the sail block most UV rays?
Yes. The woven 200 GSM HDPE fabric is rated to block up to 95% of UV rays, significantly reducing sun exposure underneath the sail.

Can it be left up in wind and rain?
The design is air and water permeable which reduces wind load and pooling, but it is not a rigid, waterproof awning; secure mounting and occasional removal in severe weather are recommended.

How should I measure for a custom fit?
Measure from D-ring to D-ring for the final dimensions and allow the recommended corner gaps so the sail can be tensioned correctly during installation.
