ShadeMart 12'x12'x17' Beige Right Triangle Shade Sail — Breathable, UV-Resistant Heavy-Duty HDPE

The ShadeMart 12' x 12' x 17' beige right-triangle sun shade sail is a heavy-duty, breathable HDPE canopy designed to cut sunlight and UV while letting air and water pass through for cooler, comfortable outdoor spaces.

This triangular shade sail blends functional performance with a clean, modern look. Woven from high-density polyethylene, it resists UV degradation while allowing rain and breeze to move through the fabric, reducing heat underneath without trapping moisture. The sail arrives with reinforced corners and stainless-steel D-rings fixed to durable white webbing so it can be anchored to posts, walls, trees or other structures with the appropriate hardware.

How does this shade sail reduce heat and protect from sun exposure?

The HDPE weave blocks a large portion of direct sunlight and harmful UV rays while remaining breathable, which lowers surface temperatures beneath the canopy. It provides sun protection without creating a sealed, humid environment.

• Blocks up to 95% of UV rays depending on angle and installation.
• Permeable fabric lets air flow for cooler shade beneath the sail.
• Design lowers perceived temperature by about 10–15°F in many setups.
• Stitched hems and reinforced corners preserve shape and tension over time.

Is the ShadeMart triangle sail waterproof and how does it handle rain?

This model is water-permeable rather than waterproof, so it won’t create ponding or funnel rain into one spot. Rain passes through the weave, making it a good choice over patios, pools and carports where drainage and airflow matter.

• Breathable HDPE allows water to drain through quickly.
• Permeability prevents water pooling and reduces wind resistance.
• Not designed to shelter against heavy, continuous downpours like a tarpaulin would.
• Recommended to angle the sail during installation for optimal runoff.

What are the construction details and how do I mount it securely?

The ShadeMart sail features a woven HDPE body with heavy-duty white webbing reinforcing each corner and stainless-steel D-rings for long-lasting anchor points. Proper mounting hardware and tensioning extend the life of the sail and improve performance.

• Material: high-density polyethylene (HDPE) woven fabric for durability and UV resistance.
• Corners: heavy-duty white webbing with stainless-steel D-rings for secure attachments.
• Installation: attach to posts, walls, trees or specialized anchors with turnbuckles and pad eyes (not included).
• Tip: measure mounting points accurately and allow slight sag for wind movement.

Can I get a different size or color and where does it work best?

ShadeMart offers custom sizes to fit a wide range of outdoor layouts. The triangular shape is versatile for layered shade patterns and works in small to large areas depending on orientation and attachment points.

• Custom sizing available — measure your site before ordering for best fit.
• Multiple colors to coordinate with exterior decor or landscaping.
• Common applications: patios, carports, pergolas, pools, yards and windows.
• Sail area is consistent despite slight manual measurement variations.

Who is this for? If you want a durable, breathable shade solution that reduces sun exposure and keeps outdoor spaces cooler without creating a waterproof canopy, the ShadeMart 12' x 12' x 17' triangle sail suits homeowners, renters with fixed anchor points, business outdoor seating areas, poolside installations, and carport covers. Choose this model when you need strong corner fittings, UV resistance, and an adaptable triangular design that complements modern outdoor settings.
