Important Considerations

Waterproof shade sails have the waterproof membrane on the underside of the shade sail.  Please note that this membrane is reflective and visible from the underside.

Waterproof Shade Sails CANNOT be flown horizontally. This fabric includes a waterproof layer, which will cause water to pool if flown horizontally. Sails must be flown with a minimum 20º slope

We cannot guarantee 100% waterproofness along the seams of our shade sails. Please see the fabric section for more details or contact us if you would like to discuss this before manufacturing

Waterproof Shade Sails require an additional 2-3 week manufacturing time depending on fabric colour. Please contact us if you would like an estimate for your fabric colour

To ensure a shade sail looks and performs at its best, tension needs to be applied correctly. Our Waterproof Shade Sails are handmade in Canada to the specifications of our patented construction method ensuring maximum longevity and safety.

  1. Advanced Tensioning System – Sails made with fabric/belt perimeter have issues with longevity and tension, especially after the first year of use. Our ATS system includes a stainless steel cable that runs along the perimeter of your sail ensuring equal tensioning, increased water run-off and zero-stretch, lengthening the life of your sail.
  2. Triple-Layered Reinforced Corners –  Our reinforced corners allow increased levels of tensioning, improving the aesthetic of the sail and its performance in wind and rain.
  3. Double-Stitched Seams – Poorly constructed seams can lead to fraying and strain on a sail’s perimeter. We double stitch our seams with high-quality UV-stabilised thread ensuring a clean even look throughout the perimeter of your sail.
  4. Non-Continuously Cabled Corners – A significant upgrade from our standard-sized shade sails, the cable in your waterproof shade sail is terminated at each corner as opposed to running continuously throughout the perimeter, allowing each side of your shade sail to be tensioned individually.

Fabric & Colour

Manufactured by Multiknit Industries

Waterproof Shade Sails are available in a large range of colours. Sun safety is one of the most important factors when choosing shade fabric, this fabric is engineered in Australia and subject to rigorous testing, ensuring up to 98% UV Protection. Waterproof fabric is fade and tear-resistant and comes with a 5- year UV warranty. If you’d like more information, please see our fabric page. Please note, with some vibrant waterproof colours you should expect a slight change in the colour of the light that passes through your shade sail.

Please note – Due to the properties of Teflon used in our stitching and the waterproof glue used in our seams, the waterproofness along the seam is not guaranteed to be 100%.  Depending on weather conditions (ambient temperatures and rain) and the design/slope of the shade sail, the seams have been known to slightly leak or drip. The waterproof glue will also need to be re-applied once on an annual basis to minimise this effect.






Rust Gold












Danish-Made Marine-Grade 316 Stainless Steel

For outdoor products, high-quality hardware is essential for both the aesthetics and the longevity of your sail. All of our hardware is made from marine-grade forged 316 stainless steel imported from Denmark. High load rated, this material is extremely strong and corrosion-resistant ensuring a polished finish for the life of your hardware.

There are two types of hardware

  1. Attachment Hardware (included) – All custom shade sails come with a complete hardware kit to attach your shade sail to your anchor points. This includes turnbuckles, which are used to tension your Shade Sail properly and allow for easy and efficient adjustment during the season and D-shackles, which attach your turnbuckles to the corners of the sail.
  2. Anchor Point Hardware (sold separately) – This hardware creates anchor points on your posts and/or structure where you will attach your shade sail to. The anchor point hardware you will need will depend entirely on your space and is therefore sold separately. Anchor point hardware can be viewed here and purchased on the Anchor Point Hardware page in our Custom Shopping Cart.

**Please Note: The hardware shown may differ from what you receive based on the size and design of your shade sail.

Shade Analysis & Design Rendering

Shade analysis plays a vital role in creating the ultimate outdoor space. Making sure you receive shade at the correct time of day is essential to ensuring your comfort and getting the most out of your shade product. Visualization is also an important part of the design process and being able to clearly see what your space will look like once your shade product is installed can help in many ways. Our Shade Analysis and Design Rendering service includes a custom 3d rendering, showing the shade pattern typical for midday in July, 3 to 4 views around your space and adaptations at no extra charge.

Shade Sails Traveller

Inspired by our nautical roots, the Shade Sails Traveller system facilitates an adjustment to the positioning of the corner of your shade sail, allowing you to move the corner and accommodate a wider range of sun positions. As a pulley system, the Traveller can also be used to apply final tensioning to the Shade Sail.

Kit includes

  • One main pulley and cleat unit
  • Two mini pulleys for the top & the bottom of the track
  • 1 stainless steel rope cleat
  • 5ft track and screws
  • Nylon rope

FAQs & Important Information

Are the sides of a shade sail straight or curved?

The sides of a shade sail are curved to ensure proper tensioning. The amount of the curve (catenary curve) depends on the shape of the shade sail and can be adjusted when ordering a custom shade sail.

A standard catenary curve is 7%; this percentage relates to the distance between attachment points. If—as shown in the diagram below—the distance from A to B is 10 feet, a 7% catenary curve is 8.4 inches (7% of 120 inches). This is the distance—shown in white—from the midpoint between the two attachment points (A & B) to the midpoint in the curve of the shade sail (C).

Curvature is not solely for tensioning purposes, it can be increased (to go around a tree or other obstruction) or decreased in some cases. Our design software automatically optimizes the catenary curve for each design.  Please get in contact with our design team for any unique requirements.

    I wanted to cover my vintage trailer for the long long rainy Seattle fall/winter/spring. The problem was it needed to be attached to the house, but still be high enough to back the trailer into the spot going downhill while also keeping within the city code for maximum square feet. The people at Shade Sails Canada where so helpful. I had lots of questions and changed my mind several times about how to have it attach to the house on that edge. We decided to have a track along fascia of the roof. They helped me find the right set up(I even got to see a computer image of it beforehand and it looks great! I felt like they really cared about helping me through the process each time I talked on the phone. I got the waterproof black sail and so far it has endured some high wind and many inches of rain. The hardware is top notch. My trailer has stayed dry. I am so happy I found this high quality product and I highly recommend it!

    It hard to tell in the photo, but all three attachment points are at different heights and the track at the top is level.
