Coolaroo® Shade Sail Installation Instructions

More complete and detailed Installation Instructions are included with your Shade Sail product including permanent installation recommendations.




Your Coolaroo® Shade Sail is designed to provide UV protection and comfort in domestic areas. When selecting the position for your Shade Sail, ensure all fixing points are structurally sound and fixings are tightly secured.  Inspect regularly.  Prior to installing, consult your local council/authorities regarding building regulations which may apply in your areas.  Exposure to certain chemicals, e.g. Chlorine, can lead to the premature breakdown of the fabric.  Chemicals to be used on or around the fabric should be referred to Coolaroo® regarding their use.  Do not have fire or open flame close to the fabric.  Do not use your barbecue under the shade structure.  Temporarily remove your Coolaroo® Shade Sail while strong wind conditions exist.



SUITABLE LOCATION(S) for your Shade Sails:

Before you commence installation it is very important that you consider the most suitable location for your shade sail(s).  Take into account the following:

      - Size of the shade sail(s)

      - Strength of the existing structures intended to be anchor points

      - Ability to insert fixing posts

      - Location of barbecues, sun direction, high wind areas, electrical/telephone cables,      

        water pipes, etc.




Resort Style (Triangle Sails)

For a Resort style effect we recommend you construct your triangle sail with one end at a low point and two ends at higher points.



Hyperbolic Style (Triangle Sails)

For a Hyperbolic style we recommend you construct your sail with two diagonal ends at a high point and the other two ends at diagonal lower points.


Shade Sails can be mounted in a variety of ways. Sails can be mounted flat or with high and low points. A flat sail can be more difficult to properly tension and can catch rain and wind. One of the best methods of mounting a shade sail is to have high points diagonally opposite each other. This creates an architectural “hypar”. Setting a minimum slope of 15 degrees is ideal. This slope creates a rise to run ratio of 1 / 3.75.  When establishing your sails lower points, make sure they are suitable for water run-off.



You should ensure all fixing points are structurally sound.  A fixing height at least 2.4m is suggested.  Allow a minimum of an additional 10% of sail length between each fixing point and the end of the Sail’s fixing accessory for tensioning.  Consider relevant building regulations, sun direction and surrounding hazardous elements.




We recommend that the fixing of the Shade Sails to trees be for TEMPORARY USE ONLY.  The diameter of the tree where the sail will be fixed must be at least 250mm.

Important: At least TWO of the sail’s fixing accessories must be tensioning devises.

A rope or chain can be used to extend your shade sail to a fixing point if required.


Suggestions of selecting the fixing accessories which best suit your own installation needs: Selecting Fixing Accessories:
There is an extensive range of fixing accessories available to help you secure your shade sails. These accessories are readily available from your normal hardware supplier


TURNBUCKLE:  To attach Shade Sail corner ring to a fixing point and provide tension on the Shade Sail.


“D” SHACKLE: Use to link Shade Sail corner Pad Eye or Eye bolt.


PAD EYE: To attach Shade Sail corner ring to a wall in conjunction with “D” Shackle.


“S” HOOK: Use to link Shade Sail corner to Pad Eye or Eye Bolt.


EYE BOLT: To attach Shade Sail corner ring through a timber stud, steel pole or solid support.


SNAP HOOK: Used to link Shade Sail corner Pad Eye or temporary use.


STRAP TENSIONER: Used to apply tension to Shade Sail during installation.


A properly mounted and tensioned shade sail will have approximately 100 pounds of tension on it and will have little to no wrinkles. Connect all points, using rope or wire cable if necessary to gain increased leverage. The rope can be threaded around a number of times so that it works as a "pulley" mechanism. Another tensioning method would be to use a turnbuckle which can aid in applying the proper amount of tension. Stop tensioning when the shade sail is rigid with little or no creases. CAUTION: Do not over tension. Tension only by hand and only tight enough to get the wrinkles out of the shade cloth. Re-tension periodically if required.

Here are some possible combinations of installation:

Pad Eye - Turnbuckle - Sail

Eye Bolt- “D” Shackle - Sail

Eye Bolt - “S” Hook – Sail




Connect fixing accessories to mounting points required. Ensure all accessories face towards the middle of the sail and are tightly secured.



Connect all points, using a strap-tensioning tool if necessary to gain increased leverage. Stop tensioning when the shade sail is rigid with a little or no creases.
