The direction of the sun
The size of the shade sail or awning
The location of any barbecues
The strength of existing structures intended to be anchor points
The ability to insert fixing posts if needed
Once you know where you’re going to put it and how big it should be you’ll need to decide on the most suitable fixing points for each corner. Existing structures such as a pergola, fence post, large tree or fascia can work. If none of these is available, you’ll need to put in a post. It’s vital to ensure that fixing points are structurally sound. If you’re not sure, consult a builder or the sail manufacturer.
Measure the area you want to cover and match a sail to this size. Small sails can be supported by timber posts or structures, whereas larger sails need strong steel posts, so keep this is mind when deciding on how big to go and how many to install.
The two main ways to tension a shade sail are with stainless-steel turnbuckles or a pulley system. If you want your shade sail or awning to be up permanently, the turnbuckle is the best option. If you’re looking to install one that is used only on an occasional basis, though, the pulley system is ideal and can easily be set up and taken down in minutes.
Unless you consider yourself a seasoned DIYer and have the right tools for the job, it’s probably best to get a builder or sail manufacturer to install your sail or awning. They will be able to assess whether the existing structures in your yard are suitable for anchoring the sail or whether poles will have to be put in. If poles need to be installed, this will require digging holes to the right depth and cementing them correctly as well as ensuring they are the correct height and distance apart to achieve the tension needed.
Why not make a design feature out of the new “roof” of your outdoor room and overlap two or more shade sails. You can get really creative by installing sails in different shapes, colours and sizes. As an added benefit, sometimes several small sails are cheaper than one big one.
There is an abundance of products on the market, particularly when it comes to shade sails, and many are very cheap. However, as always, you get what you pay for and cheaper models are often made of poor-quality materials and are not durable enough to withstand weather conditions for any length of time or to last if permanently erected.
It’s also important to check the UV protection rating on the fabric. Quality shade sails are usually made from vinyl or a high-density polyethylene, which is a flexible but strong knitted fabric that provides protection from the sun while still allowing air to flow. Many cheaper models made of substandard polyethylene fabrics offer little or no UV protection, despite their claims. Look for some sort of certification or guarantee.
Are you protected from the sun?
Shade cloths can be susceptible to stretching, which can be due to the wrong or inferior material being used in the first place, as well as from incorrect installation and deterioration. Stretching can reduce the UV protection. For this reason, correct installation of a quality product is essential, so it’s always a good idea to have a qualified builder or reputable manufacturer with specific experience in this area do the installation.
Safety and regulations
Before installation, make sure you check with the local council for any relevant building regulations.
Ensure your fixing points are structurally sound and are secured tightly. Check them regularly.
Don’t use your barbecue under the shade structure and make sure there is no fire or open flame close to the fabric.
