Tips On Shade Sail Installation

home | products | contact us | faxback quotation form


Installing a simple shade sail can make your deck or backyard sun smart. A smart DIY approach can save a lot of money by avoiding specialist installation costs.

A shade sail supported by posts is essentially a small construction project. Holes need to be measured and dug, posts sourced and concreted in. Multiple site visits are also needed to secure accurate measurements throughout the project. All of this comes at a cost.

Many competent DIY’ers tend to buy a shade sail only as they have already worked out which posts or other strong fixing points they are going to use. This approach can offer big savings on third party installation costs. Mulder’s principal shade designer suggests four main points to getting the initial DIY plan correct.

Firstly decide where shade is wanted and measure the sides and diagonals of this whole area. A common error is to buy a Ready Made Shade Sail, get it home and find it will not match up with available fixing points. We recommend that customers first work out their fixing points and measure from these to design their final sail size.

Secondly allow for the fact the sail covers a smaller area after allowing for fixings and tension curvature. To ensure the shade sail is stable in winds it must have some curvature and not be on one level plane. The most common method is to have each pair of diagonally opposite corners at significantly different heights.

Sails that are not properly tensioned end up holding water, hanging limp and becoming unstable in heavy winds. Sails work best when they are under enough tension to give curvature, are not on a level plane and are 'twisted' for stability

Finally ensure that any proposed fixing points are strong enough to bear the stresses of a sail under strong wind conditions. Proposed fixing points like walls or roofs are sometimes too weak to withstand the load of a sail under wind pressure. If unsure consult a local engineer.

Once the overall dimensions are finalized, the sail cloth area and the number of fixing devices needed to pull the sail into tension can be costed.
