Shade&Beyond Triangle Sun Shade Sail 15'x15'x21' Light Grey Permeable HDPE Canopy — UV-Blocking, Breathable

The Shade&Beyond Triangle Sun Shade Sail is a breathable, UV-blocking triangular canopy (15' x 15' x 21') that creates cool, comfortable outdoor shade while allowing airflow.

This light grey permeable sun sail is designed to protect patios, decks, gardens and poolside areas from intense sun without trapping heat. Constructed from 185 gsm high-density polyethylene (HDPE) fabric with reinforced seams and stainless-steel D-rings, the sail provides durable, long-lasting shade while promoting ventilation. It’s engineered to block the majority of UV radiation and reduce glare, yet it’s not waterproof—curved edges and the permeable weave help rain pass through instead of pooling.

How does this shade sail reduce heat while staying breathable?

The fabric’s high-density weave blocks 85%–88% of direct sunlight and reflects a large portion of solar energy, lowering perceived temperature underneath. Because the material is permeable, it encourages air movement so heat doesn’t accumulate beneath the sail.

• 185 gsm HDPE fabric for effective sun blockage and durability
• Permeable weave improves airflow and reduces trapped heat
• Curved edges prevent water pooling and prolong fabric life

What should I know before installing this 15' x 15' x 21' triangle sail?

Measure from D-ring to D-ring when planning your attachment points and account for 1.5–2 feet of extra space for hardware and tensioning. For the best fit, choose a sail size around 88% of your installation span to prevent excessive sag; a separate mounting kit is required but not included.

• Install by measuring D-ring to D-ring for accurate placement
• Allow 1.5–2 feet of clearance for turnbuckles, chain or rope
• Recommend sail size ≈ 88% of the open span for optimal tension

How durable is the Shade&Beyond triangle shade and how do I care for it?

The sail features reinforced stitching and stainless-steel D-rings to resist wear from regular outdoor use. Maintenance is simple: remove the sail in storms or high winds and clean with mild soap and water; avoid high-pressure washing or bleach to preserve the fabric’s integrity.

• Sturdy, well-stitched seams to prevent fraying
• Stainless-steel D-rings at each corner for secure anchoring
• Remove during severe weather to maintain performance

Where does this shade sail work best and what benefits can I expect?

Use the sail over patios, decks, pergolas, pool areas or small gardens to create a cooler, more private outdoor space. It significantly cuts sunlight exposure and glare while enhancing comfort for gatherings, relaxation, and outdoor dining.

• Ideal for patios, gardens, pools, decks and pergolas
• Blocks roughly 95% of harmful UV rays while offering 85%–88% shade
• Enhances privacy and creates a pleasant shaded zone for activities
