Custom vs. Standard

A Custom Shade Sail gives you the freedom to create almost any shape you want in a Sail, allowing  you to benefit from maximum Shade and Aesthetic.

In many cases a Custom Sail is also the most economical solution, as we can create your Shade Sail to attach to your existing anchor points (House, Garage, Large Tree, etc) instead of adding multiple new posts. 

You simply provide us with accurate measurements of your space (Anchor point to anchor point) and we make your sail to fit, considering stretch, hardware and all. This is as simple as it sounds.

This allows you to see how the Sail will look in your space, tweak any design details, ie: Anchor points, heights, size etc before you send us measurements to order.

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.

What is the UV rating of our Shade fabric?

UV ratings range from 89.3% to 97.7% depending on your fabric and colour. Your colour choice will not noticeably affect the temperature under the sail.

Note: the surface you are standing on may reflect the sun more than others so the sail rating does not consider UV coming off the ground surface and bouncing up.

Why are flat shade sails inferior?

We always aim at providing Shade Sails that are not only well tensioned, but perform optimally too. A flat Shade Sail - meaning all the anchor points are at the same height, or the Shade Sail lies on a perfect slope with both high points at the same height and both low points at the same height - will always catch the winds. This is why we prefer to alternate and vary anchor heights in order to get more shape out of the Shade Sail and give the system better aerodynamics. Designed by Shade Sails Canada and installed following our instructional videos, your Shade Sail should be extremely rigid and you should experience very little to no movement at all in your Shade Sails especially in periods of higher winds.

Are posts included?

It depends! In a commercial setting, we provide full turnkey solutions whereby we oversee not only the fabrication and finishing of steel posts but the installation of them as well. In a residential setting, we provide you with all the specifications pertaining to your posts, whether they be steel or pressure treated wooden posts.

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.
