Royal Shade 16' x 20' Grey Rectangle Sun Shade Sail — UPF50+ 95% UV Block, Breathable 200 GSM

Royal Shade 16' x 20' Grey Rectangle Sun Shade Sail is a heavy-duty, breathable outdoor canopy that blocks up to 95% of UV rays while letting air and rain pass through to reduce heat and prevent pooling.

Designed for patios, decks, poolside, and carports, this 16' x 20' rectangle sail from Royal Shade combines high-density 200 GSM HDPE fabric with reinforced construction to deliver durable sun protection and a cooler outdoor space. The grey tone blends with modern exteriors while the breathable weave helps maintain airflow and channel water away without forming puddles. Built-in stainless steel D-rings and a curved-edge design help the sail hold tension and resist sagging, and Royal Shade offers three years of manufacturer support plus custom sizing on request.

How does this shade sail reduce temperature and sun exposure?

The sail uses a tightly woven 200 GSM high-density polyethylene fabric rated UPF 50+, reflecting and absorbing a large portion of solar radiation to lower surface temperature. By blocking about 95% of UV, it reduces direct sunlight on people and outdoor furnishings, helping them stay cooler and protected from fading.

• UPF 50+ fabric blocks most UV rays and reduces heat buildup.
• 200 GSM HDPE provides a durable, sun-resistant barrier.
• Grey color minimizes glare while complementing outdoor decor.
• Recommended 0.5–1 ft extra for mounting hardware to reach optimal tension.

Will the canopy let rain and air pass through without sagging?

The breathable, open-weave construction allows wind and rainwater to flow through instead of collecting on the surface, reducing ponding and strain. Curved edges and reinforced double stitching keep the sail taut and centered, preventing the common sag that leads to water accumulation.

• Permeable weave channels rainwater downward to avoid pooling.
• Curved edge design preserves tension across the canopy span.
• Double layer stitched seams and stainless steel D-rings add strength.
• Easy-to-clean fabric and simple storage make off-season care straightforward.

How easy is it to install and maintain the shade sail?

Installation is straightforward on existing structures; attach the sail to anchor points using appropriate hardware (not included) and leave the recommended clearance for tensioning. The fabric is low-maintenance — periodic rinsing or mild soap cleans most dirt — and the sail packs compactly for storage when not in use.

• Attach to posts, walls, or beams using proper hardware for stable setup.
• Allow 0.5–1 ft extra fabric for mounting to achieve correct tension.
• Spot clean with water or mild detergent; air-dry before storing.
• Hardware kits are available separately for reliable anchoring.
