Shade&Beyond Triangle Sun Shade Sail 12'x12'x12' Dark Grey — 185 gsm HDPE, 85–88% Sunblock

Shade&Beyond's 12' x 12' x 12' triangle shade sail is a breathable HDPE canopy that cuts sunlight while encouraging airflow to cool patios, decks, and yards.

This triangular sun sail is woven from 185 gsm high-density polyethylene fabric and finished with reinforced seams and stainless steel D-rings to withstand regular outdoor use. Designed to provide substantial UV protection without trapping heat, the permeable fabric reduces sun exposure while letting breezes pass through. The dark grey color creates a modern look that complements many outdoor styles and hides dirt between cleanings.

How much sun protection does this sail provide?

The Shade&Beyond triangle sail blocks most direct sunlight and filters harmful rays for comfortable shade. Expect approximately 85%–88% sunshade and up to 95% UV-ray reduction, ideal for lounging or shaded dining outdoors.

• Fabric blocks 85%–88% of visible sun intensity
• Rated to reduce up to 95% of UV exposure
• Permeable weave lowers heat buildup beneath the canopy

What are the key construction and durability details?

Built for outdoor conditions, the sail uses heavy-duty 185 gsm HDPE cloth with double-stitched seams and corrosion-resistant D-rings at each corner. Curved edges help water run off instead of pooling, but the material is not fully waterproof—it's optimized for shade and airflow.

• 185 gsm high-density polyethylene fabric for strength
• Stainless steel D-rings securely anchor the corners
• Curved hem reduces water accumulation and stress

How should I measure and install the shade sail?

Measure between the D-rings when planning installation and allow 1.5–2 feet for mounting hardware and tensioning. For best results, size the sail at about 88% of the measured area to maintain proper tension and reduce sag; hardware is sold separately.

• Measure from D-ring to D-ring for accurate fit
• Leave 1.5–2 feet clearance for turnbuckles or eye bolts
• Choose a slightly smaller sail than opening (about 88%) to prevent sag

How do I care for this sail to extend its life?

Routine upkeep is simple: keep the fabric clean, inspect attachment points, and remove the sail during severe weather to prevent damage. The breathable cloth reduces mildew risk, but occasional washing and periodic checks will keep performance consistent season after season.

• Detach and store the sail in storms or high winds
• Spot-clean with mild soap and water; air-dry fully before storage
• Inspect D-rings and mounting hardware regularly for wear

Who is this for? The Shade&Beyond Triangle Sun Shade Sail is made for homeowners, renters, and small-business owners who want a stylish, low-maintenance way to create shaded outdoor space. It suits patios, poolside seating, garden play areas, pergolas, and café terraces where airflow and UV reduction matter. If you need a specific footprint, Shade&Beyond offers custom sizing so the sail can be tailored to irregular areas or unique mounting setups. Note that installation hardware is not included, and the fabric is designed for shade rather than full waterproof protection.
