The recommended fitting for 8 square metres and above, would be an M8 eye bolt through a post, with a fork / fork adjustable rigging screw between it and the ring (which is included in the corner of the Shade Sail). So, this "fixing allowance" (bisecting the corner angle) would be between 200mm and 270mm.
For an M8 eye bolt through a post, with the smaller Hook/Hook adjustable rigging screw, then the 'fixing allowance' (bisecting the corner) would be between 175mm and 235mm.
Normally you should use a threaded turnbuckle on each corner (that can be adjusted for length to create the tension across the Shade Sail) attached to a good anchorage. It is possible to fix one corner close to an anchorage with a shackle and maintain the tension using the other corners, but more than one corner fixed like this prevents the tension being pulled in to the sail.
The easiest way is to fix the anchorages first, and then use a length of low-stretch string to gauge the distance between them (measuring this afterwards with a tape measure). For Shade Sails with more than three corners, split the shape in to a series of imaginary triangles and measure the distances between all anchorage points.
In this situation a wire strop provides a good answer. Our experience in rigging yachts means we have everything available in-house, from rope to wire and webbing with turnbuckles, so wherever the installation is, we have the appropriate solution for it.
In our experience shapes of more than about 10-15 square metres are difficult to manhandle and hang, are prone to sagging over time and have high windage. If your area is more than this it is worth splitting it in to a series of smaller shapes that overlap – and this has the added bonus of creating an eye-catching layered structure that places less stress on each fixing.
The British climate is capable of removing tile roofs, let alone tensioned fabric structures shaped like sails, so although small Shade Sails in sheltered spots are probably going to survive, expect instead to treat a shade as a seasonal structure for use from early spring through until mid to late autumn.
Good advice and phone support! All Shade sails come complete with the reinforcing eyes in each corner, allowing you to choose the method by which you hang them. This is because we don’t want you to pay for anything extra you won’t use.
All our Shade Sails are made to very high standards, with a strong webbing reinforcing band running concealed along all edges and through welded stainless steel eyes in each corner. Check your anchorages are sound however, as we make our Shade Sails to the same rigorous standards as our ocean going yacht sails, some of which are designed to survive Hurricanes!
We offer a bespoke design service to create a sail to fit any size or between any distance fixings (within reason!). Speak to one of our experts in house and after a brief consultation they should be able to create an exact fit. Our bespoke Shade Sails have appeared in property magazines and garden exhibitions nationwide and enjoy an excellent reputation. Alternatively, use a standard sized sail and fill the gap between sail corner and fixing point with a wire strop.
Solacryl Acrylic or VALMEX P.V.C. are the best choices as they are both water \'resistant\', and to a high degree. However, please note you may still get a little seepage through the sewn seam holes. Both materials are available in a wide range of colours.
Additionally, we recommend AT LEAST a 20 degree slope (that is 36cms drop, in 1m across) for adequate water run off. Especially if your shade is likely to be left up for an extended length of time. Note, also it should also be taut, so that it doesn\'t sag as the water droplets land.
The Sunsure mesh fabric is purpose designed as a UV filter and has been used extensively in primary schools for exactly this purpose. It the most practical fabric for the UK climate - but we recommend only leaving it up between April and October, and consider taking it down if the weather gets really nasty too.
The best choice of fabric is dependant on how and when you will be using your shade, what you intend to use it for, and perhaps also what colour you want. Also, some materials are easier to clean than others. A simple guide to each fabric\'s features can be found on the fabrics page of this site. Sunsure is a mesh fabric so it is not water resistant, but it is less affected by stronger winds than the "solid fabrics" such as Solacryl and VALMEX. All the fabrics are available in a wide range of colours.
