The shade sails are designed to withstand the wind. But the type of canvas used, especially the density of its mesh, will influence its durability. As well as the finishes, especially those of the points of attachment, where the shade sail will undergo the most tension in the event of strong wind. Sails sold for individuals are generally not intended to stay outdoors throughout the year. It is recommended to dismantle them in winter.

Until what wind force can resist a shade sail?

A quality shade sail will mention the maximum wind power to which it can be exposed. At Espace Umbrage, our sails can withstand speeds of 60 km / h (for Acryl 300) to 80 km / h (for Austral 220 and Austral 340 ). The sails with furler support the wind even more.

But in this case it will be necessary that the sails are rolled so that they can withstand strong winds.

This power (60 or 80 km / h) corresponds to a large number of winds on the Hexagon, mainly in the summer season. Nevertheless, in some very windy regions, or in winter, when the winds become more violent, the sails of shade could suffer more and deteriorate.

What are the characteristics of a sail that is resistant to the wind?

The wind will exert tension on the shade sail. To prevent it from tearing, you will prefer the sails:

• That offer tie rings rather than eyelets

• The edges of which are reinforced, especially via a hem with a reinforcing strap

• which have curved edges, to improve the tension of the canvas

The more the canvas is stretched, the less it will move in the wind, at the risk of becoming fragile. The tension should be between 30 and 50 kg to be effective. It is exercised in the corners of the shade sail, at the points of attachment, thanks to tensioners. In a windy area choose triangular sails instead of quadrilateral sails, by nature they will resist the winds better.

What are the other fragile areas in the event of high winds?

A sail that is too fragile can tear if the wind bites against it. But she is not the only one to face it. Fixing masts, like the points of attachment on the walls or others, are just as badly manhandled.

It is therefore very important to opt for fixings corresponding to the surface on which they will be used, which will avoid seeing them torn off leaving a gaping hole behind them.

A firmly planted mast and wall fixings (long preferences), will be essential. Prefer to opt for fastening systems with tension adjustment to obtain a flat sail.

What precautions to take in case of wind?

As soon as the winds exceed the speed supported by the sail, and even before the weather forecasts strong winds, it is more than advisable to fold your shade sail, in order to improve its life.

At Espace Umbrage, we offer  sails with reel to facilitate this step: in less than a minute, you can put it safe, as redeploying as soon as time allows. For even more ease, you can even turn to electric reels .

The shade sails we offer are designed using a technology derived from the manufacture of the sails of boats, so designed to withstand the wind. The meshing of the canvases plays on this effect: an impervious sail, with a tighter weave, can not withstand the same winds as a more permeable sail. That's why our Acryl 300, water repellent range, will not face the same storms as our Austral sails. All however, are planned to offer you the best results in terms of durability over time. This is why we also offer you  a 2 to 5 year warranty depending on the shade sails you choose to install.
