Shade Sails

Why Choose a Shade Sail?

Covering areas of the great British outdoors is a growing trend, from nursery schools to nature reserves, cafés to car parks the requirements run on. The importance of learning outside the classroom and access to all-year-round outdoor play has also led to an increase in the canopy market. Often these needs are met and arguably sometimes better served with steel and polycarbonate type structures however fabric has a large part to play in canopy design and construction often offering more flexible design and great looking fabrics structures at often less money.

In addition, we are more knowledgeable than ever before about skin cancer and its causes, children are most at risk from the sun’s harmful UV rays therefore shade provision for children is vital. There are around 10,500 cases of melanoma diagnosed each year; the number of cases had almost tripled since the early 1980s. Over 2,300 people die from skin cancer each year in the UK. In fact, there are more skin cancer deaths in the UK than Australia, even though Australia has more cases of the disease. A single case of sunburn for a young person can have dire consequence later on in life proving that areas of shade is essential for all schools.

How Do You Design My Shade Sail?

A good sail shade design means efficient manufacture, straightforward installation and ultimately, good value. We are always focused on the design of your sailshade, making sure it has the right shape, is supported appropriately, and is therefore the best solution overall. When properly tensioned, a Shade Sail will not wrinkle, sag or flap in the wind. Shadesails that are not properly tensioned end up holding water, hanging limp and becoming unstable in heavy winds. Shade Sails work best when they are under enough tension to give curvature, are not a level plane and are ‘twisted’ for stability.

If you are not choosing one of our standard Shadesail designs, we will ask you at the early stages of the enquiry about the shape that you would like the Sail Shades to take. We do this to make sure we fully understand your expectations before we can begin to outline a form that works perfectly for you and the application. From sketch drawings, design development then continues, working out specific forms, interactions of the steel and fabric, water run-off etc. This culminates in a complete design proposal that is ready for sign-off.

At the start you should consider the most suitable location and design for your Shadesails taking into account many factors:

1. The direction of the sun, as you want to provide the maximum shade for your area.
2. The location and heights of your fixing points.
3. It’s important to ensure there are differing heights for your fixing points, as you do not want the sailshade to lay flat. By ensuring you have a ‘twist’ in your sail shade, not only will it be more aesthetically pleasing to the eye, but it can be tightened up more effectively, and will reduce sagging in the middle of the Shade Sail.
4. It’s best to have four fixing points, two low and two high, diagonally opposite each other. Keeping in mind where the sun is, you will want a low fixing point to block out the sun. The higher the fixing point, the more likely the sun is going to shine underneath the Shade Sail.
5. When choosing Shadesail positions and layouts, be aware of any underground services in the vicinity, if we are carrying out the installation we will need to be advised of these.
6. Does the Shadesail need to add year-round value by being waterproof?

Are Foundations Needed?

In a ‘standalone’ contract i.e. where the Shadesail is the main or only item/works package we will take responsibility for the whole project including foundation design, construction and reinstatement.

Where the shade sail is part of a larger scheme the client would often have their own “design and build” team of architect, structural engineer and main contractor. In these cases the main contractor usually excavates for and provides the shadesail foundation as designed by the client’s engineer.

Shade Sail footings range in size according to the height of the posts. As an approximate guide, one third of the total length of post will be embedded in concrete in the ground, with the remaining two thirds above the ground. Widths of footings are often 600mm – 1200mm, this increase according to the Sailshade size and diameter of posts.

What Posts and Other Fitting Points Will I Need?

We recommend the use of steel posts ranging in size from 140mm diameter up to 500mm diameter dependent on the size of the Shade Sail. The taller (higher) the post and the bigger the Shade Sail, then the larger the posts will need to be. (This will be the same for the Shade Sail footings).

Wooden posts can warp which place the sail out of alignment and can rot over time and lose their strength. (Galvanising is where the steel is submerged in molten zinc and when the zinc reacts with the steel a protective coating is formed). This coating improves the steels anti-corrosion performance to ensure it lasts as long as possible with little to no maintenance. In many cases, a topcoat is advisable applied in the form of a polyester powder coating or a wet paint system. Some structural sections are too large for hot dip galvanising so a wet paint primer system may be used.

If attaching Shadesails to existing structures, you must ensure that the structure is adequate to handle the loads applied to the Shadesail fixings during instances of poor weather and high winds. If unsure, we can advise on this. We engineer our posts and footings to ensure structural integrity, longevity and superior performance. They are also installed at the depth required to ensure your Shadesail will be safe and structurally sound for years to come.

There are a range of different caps available for the top of Shade Sail posts’ however we always recommended welded caps for longevity and improved aesthetics.

What Fabrics are Shade Sails Made With?

Included in our service is the development, in 3D of the fabric form, with industry-specific fabric form development software, using fabric panel shapes to create the appropriate form. This is developed in conjunction with our engineers in order to avoid excessive load, be it wind, snow or physical weight.

The two most popular fabrics used in external canopy structures are high density polyethylene shade cloth and PVC coated polyester PTFE coated glassfibre is another option for larger structures.

High density polyethylene shade cloth is manufactured specifically for shade sails. The long direct sunlight life of fabric is guaranteed by treatment with UV stabilisers. The average shade rating of Sail shade fabric is about 90%. The UVR block is close to 95%. That’s what makes our Sail Shades an excellent protection from skin cancer.

PVC (poly vinyl chloride) coated polyester is the waterproof option. The PVC coating includes various agents and pigments to help prevent degradation of the “high strength-low stretch” polyester base cloth, and the top coating area of an especially high quality, to minimise dirt build-up, to facilitate leaning and to maintain the appearance of the fabric for many years. All but the most lightweight fabrics developed for canopy use would have a life expectancy of at least ten – twenty years.

PTFE (poly tetra flouro ethylene) coated glassfibre offered a truly long-life material. The RTPE coating is resistant to virtually all chemicals, and will not degrade in the harshest of climatic condition. The material has a life expectancy in excess of 20 years, although there are some structures in this fabric that have been in existence for even longer than this.

Many Sailshades are made by joining flat fabric strips together and then marking the Shade Sail shape out on top of the large panel and then cutting it out. The result is a flat shape which when installed, is forced into 3D shape through shearing force. While this approach appears to work, it is often only short term, ultimately there are limitations and typically these Shadesails will have a shorter life than properly patterned sail. These Shade Sails will often be flatter than desirable in order to overcome wrinkles in the body of the sail which result from lack of proper patterning. While you may be shown photos of apparently excellent Shadesails as evidence to demonstrate qualifications and competency, bear in mind it is unlikely you will be shown photos of the large number that “didn’t quite work out” or photos of the “nice Shadesails” a few years later when they have either sagged or flogged themselves to destruction.

Correct patterning results in 3D shape when the fabric panels are joined without the need for shearing force. The strips of fabric have curves cut in the sides which are defined by 3D patterning software and are usually cut on a computer-controlled plotter/cutter.

There are basically two types of Shadecloth fabric which are defined by their construction, mono/tape and mono/mono.

Mono/tape fabrics are constructed using mono filament yarns (similar to fishing line) with flat or elliptical shaped tape woven through them to help close up the gaps and thereby afford higher shade performance whilst keeping the fabric light.

Mono/monofabric has no tape so is typically heavier as it requires much denser weave in order to achieve required shade performance figures. These fabrics typically provide higher tensile strength than mono/tape fabrics and are much more stable – i.e. they have similar technical performance figures in both weave directions.

Shadecloth Weight – typically correlates directly with tensile performance – heavier fabric is generally stronger than lighter fabric and is, therefore, typically used for larger Shade Sails and light fabric for smaller Shade Sails. Fabric weight falls into broad groups, light 200-250gsm, medium 300 to 350gsm, heavy >350gsm.

Fabric weight also correlates directly with forces applied to structures which the sail is attached to. Heavier/larger Shade Sails require higher stresses to be applied to ensure the sail is sufficiently taught and therefore exert larger forces on posts resulting in larger steel sections and footings/foundations.

Another example of marketing misinformation is the claimed shade performance number typically 90-98%. This number is determined by placing a small sample of fabric on a light source and measuring light transmission through the fabric. The test bears no relationship to how the fabric is used in Shade Sail application. When the shadecloth is stressed in both directions gaps appear in the weave changing the ability of the fabric to provide claimed shade performance numbers. The small difference in performance between the “90%” group of fabric is in our opinion insignificant given the fact they all stretch when deployed. The important thing is to ensure that the fabric is real commercial grade and in the 90% category (70% and 80% fabrics are unsuitable for use in human protection applications).

The majority of Sail Shades are too big to fit inside the width of fabric off the roll therefore, they are made by joining strips of shade cloth together to form larger panel – this process is called seaming.

Seams should be carefully located with aesthetics in mind – Shade Sails, after all, are not just functional and should include an architectural element. Let’s say your sail is 4m wide and the fabric width is 3.8m wide – where is the seam going to be located. All too often cheap sail will be made by joining thin 200mm strip of fabric to one side of the 3.8m to make the 4m – while functional and low cost – visually, it is very unattractive. Another common problem is the method used for seaming, professional high performance Sail Shades should be made using the Lap Seam with rows of lock stitching to provide full shear capacity.

The most commonly used low cost threads are a blend of polyester and cotton – these are UV stable, however, typical life expectancy in Shade Sail application is between 5 and 15 years depending on the amount of stress. Thread strength drops by up to 50% over this time due to exposure to UV – the higher the sail is stressed the quicker it will fail. High performance Shade Sails are made using PTFE thread which costs 10 times the price of a comparable poly-cotton blend. PTFE threads loose less than 20% of their strength with UV exposure over 10-15 year period.

The two commonly used edging methods for Shade Sails are webbing and cable. Both methods are suitable for making Sail Shades however load capacities vary. If webbing is used then it should be placed on the bottom side of the shade fabric to protect the web from UV radiation.

How Are They Fitted and Attached?

The most commonly used shade sail corner fitting is stainless steel “O” Ring. These are available in various quality standards and sizes. The fitting is created by forming a piece of solid rod to the required shape. The low end uses or 6mm thick 304 grade rod which are formed but often not welded closed – they have very low strength and will be prone to rust. These fittings are suitable primarily for small budget Shade sails and internal applications. High performance Sail Shades use a thick “O” Ring made from 316 grade stainless steel.

Rings are used to fasten the Sail Shade by either a shackle or turnbuckle to a point either on a post or an existing structure. Each corner of our Shade Sails has an extra layer of cloth and strapping which serve the purpose of distributing forces.

The perimeter of each Sail Shade features a curve that controls the tension of fabric in the centre of the sail. The fabric, therefore, has uniform tension throughout.

All our Shadesail fittings are marine grade 316 stainless steel or chrome-plated brass, which not only look tasteful and modern but have also been tested for their strength and durability to ensure their longevity.

Beware and avoid the hook style turnbuckles which are often used by Shadesail suppliers for their convenience during installation. Aside from the danger posed by one of these coming un-hooked in high winds. In our opinion, hook turnbuckles are completely unsuitable for use in Shade Sail applications. Beware of firms using any type of fixing that you could not adjust without specialist equipment if you chose to, this is a ploy to tie you into their maintenance service.

How Do I Care for My Shade Sail?

To clean your Shade Sail, we recommend the use of a mild detergent with the use of a low-pressure water hose and a soft scrubbing brush. Do not use abrasive cleaners or a stiff brush. Do not use chlorine-based cleaners.

Ensure that the Shade Sail does not come into contact with chemicals, as this will damage your Shadesail, and this is not covered by the warranty.

It is advisable to take your Sail Shade down in the winter months. It’s preferable to store the Shade Sail in a protective bag to keep out the vermin.

Fabric is a great diffuser of light. The top surface of the canopy may become dirty over time, but from the underside, the surface soiling is rarely noticed. Although the translucency of the fabric will have reduced accordingly, it’s quite surprising how little this affects the comfortable levels of light under the membrane.

In most cases, Shadesail cleaning is a very easy operation to carry out. The purpose is primarily to remove built-up areas of permanent dirt, on both the fabric and the steelwork which can act aggressively against the surface. A secondary benefit is improved brightness under the canopy.

It would be good practise to clean most structures every couple of years. However, on large structures, access to all areas of the canopy is unlikely to be easy, so cleaning may well be less frequent. In many cases, however, cleaning can be quickly and easily carried out by any cleaning contractor or caretaker using mild detergent, soft brushing and lots of clean water to rinse.

By ensuring long term cleanliness of the Sail Shade, the benefits will be a longer life for the fabric, and a better looking, better-maintained structure.

However, it’s important to stress that all of our Shadesail fabrics are extremely strong and durable.

Will I Get Any Warranty?

Most shade-cloth suppliers offer 10 year warranty which we recommend you consider of little or no value. The warranty is typically against “UV Degradation” only and is voided if the sail has been “over-stressed”. Both conditions are difficult to prove particularly since suppliers do not specify how much stress is “over-stressed” and installers don’t measure pre-stress. Mostly, warranties only cover the supply cost of the fabric on pro-rated basis, i.e. in 5 years if you can prove claim of UV Degradation, then they will pay 50% of the cost of the fabric (when it was purchased) provided your supplier is still in business and can produce receipt to prove the purchase. There is no contribution to the cost of removing, remaking and re-installing the shade – labour is the highest component cost of professionally manufactured and installed Shadesail.

The most valuable warranty is the one offered by the Sail Shade supplier so it is important that you select a reputable supplier who understands firstly, how to design good sailshade and then how to make a quality sail. It is also important to deal with a company who will be in business long enough to provide support if required!

Where Can Shade Sails Be Installed?

Shade sails are a fantastic covered solution for a wide variety of applications and environments, including:

Nurseries & Primary Schools

Shade sails are a perfect addition to any nursery or primary school playground. Thanks to the UV protection properties of our high-strength fabric cloth, shade sails allow nursery children and primary school pupils to play outside and enjoy the fresh air while remaining safe from harmful exposure to the sun. The safety of children in any nursery or junior school is of utmost importance; so, too, is giving them the freedom to play, learn and socialise outdoors, which will positively contribute to their overall early development.

What’s more, our shade sails’ bright, eye-catching colours will go down a treat with young children while their robustness and durability mean they’re built to last, even with little ones running about!

Secondary Schools & Sixth Form Colleges

Shade sails serve many different purposes in secondary schools and sixth form colleges. A popular choice for outdoor seating areas, shade sails give senior school students a shaded and sheltered space to eat their lunch alfresco style — or to simply socialise and hangout with their friends while enjoying the fresh air. This will do wonders for your students’ productivity and overall well being which, in turn, will help to raise your school’s reputation. Furthermore, instead of taking the costly route of extending your dining room, bespoke shade sails allow you to increase your seating capacity in a much more affordable (and aesthetically-pleasing) way while keeping your students onsite and out of trouble during lunchtimes and break periods.

Colleges & Universities

With many colleges and universities across the UK having benefited from multi-million pound developments over the last few decades, it’s important that you find a covered solution that complements your state-of-the-art campus without looking out of place. Shade sails do just this. Combining practicality with aesthetic beauty, they allow you to provide your students with much-needed shade and shelter, whether it’s for studying, socialising, eating or meeting outdoors, while enhancing your campus in a way that captures the quality of your higher education courses. Thanks to their structural solidity, high-strength materials and striking design, shade sails not only improve the experience of your current college or university students, but are sure to impress future applicants upon their visit to your campus.

Parks & Public Spaces

When it comes to parks and public spaces, a covered area solution needs to be both fun and functional. Lucky for you, shade sails tick all of these boxes. Thanks to their tensile UV-resistant fabric, shade sails provide much-needed shade for children, safeguarding them from the sun’s harmful UV rays as they play in the park. They can also be used for outdoor seating or café areas to keep parents safe, dry and cool while they keep an eye on their children. Our high-strength, high-quality materials mean our shade sails are built to withstand the rough and tumble of a childrens’ play area, as well as our unpredictable British weather! Thanks to their vibrant shade sail designs and variety of colours and finishes, our shade sails add brightness and buoyancy to any park or public space.

Garden Centres

Shade and shelter is absolutely essential in any garden centre. Covered solutions are needed to protect not just your customers, but your products, too — especially wooden, steel or metal items that can degrade when exposed to the elements for too long. Shade sails can do just this, providing shade and shelter from whatever our unpredictable British weather throws at us while enhancing your garden centre site. Beyond their purely practical benefits, our range of stylish shade sails can improve your garden centre’s hospitality provision, especially when it comes to your onsite café or refreshment area, giving your customers a place to sit down, relax and enjoy a hot cuppa and a tasty treat.

Public Attractions

Between outdoor eating areas, viewing areas and queuing areas, there is a high demand for covered spaces at any public attraction, whether it’s a theme park, a zoo or a museum. Shade sails provide shade and shelter for all of these applications, ensuring your visitors remain dry, safe and protected so they can enjoy their day to the fullest.

A sleek, stylish and striking shade sail can be an attraction on its own, so installing one at your entrance or around your exterior can help to drive more people through your doors.

Pubs, Restaurants & Hotels

Whether you run a pub, a restaurant or a hotel, comfort is something that will always rank high for customers when deciding where to spend their money — and shade sails provide just this. From creating a cool, shaded and UV-resistant area in the hotter months to providing a dry, sheltered and wind-protected space in the wetter ones, shade sails are an ideal solution for outdoor areas in the hospitality industry, whether these areas for eating, drinking, smoking or waiting.

Shade sails can not only improve the experience for your existing customers, but they can help you to attract new customers, too. Thanks to their elegant design and bright, bold colour schemes, shade sails are guaranteed to catch the eye, enhance your establishment and help you to entice more paying customers through your doors.

What are the Benefits of Shade Sails?

Weather and UV protection

With shadecloth or waterproof fabric options, rain or shine, you can rest assured that a bespoke shade sail from A&S Landscape can protect you from all the elements. While most of us can agree that getting plenty of sunshine is important — not only to our tan levels, but to our health and happiness — too much exposure to direct sunlight can increase your risk of skin cancer. That’s why UV protection is so important, especially for young children who are most likely unaware of this danger.

At A&S Landscape, our shade sails use high-quality shade cloth that offers 90-98% UV protection along with a multi-year UV degradation warranty. Whereas in the past shade fabric would often suffer from UV degradation, we add UV inhibitors to our shade cloth during the manufacturing process, ensuring it provides safe protection from the sun for many years to come.

As an alternative to shade cloth, we use PVC fabric, which is an excellent waterproof option that boasts an even longer lifespan.

Sleek and stylish

Our shade sails aren’t just functional and durable, but they add a bold, elegant and dynamic focal point to your premises. Between the Maxima Sail™’s sleek and striking appearance, the Maxima Umbrella™’s smart and timeless design, the Maxima Tepee™’s snug yet sturdy feel, and the Maxima StarSail™’s trendy and breezy look, our range of high-quality shade sails will enhance any space, whether it’s a school playground, a college or university campus, or a pub or restaurant.

Affordable and cost-effective

Shade sails offer high-quality shelter without the high costs. Thanks to their minimalistic designs, they’re reasonably priced and offer great value for money while still delivering all the benefits you want from a covered area solution, including weather protection, UV resistance and a long lifespan. When used to provide cover for outdoor eating areas, shade sails are a far more affordable and cost-effective way of increasing your seating capacity without having to extend your dining room, which can be a disruptive, time-consuming and not to mention an expensive endeavour.

Easy to install

No matter how large or small your shade sail structure is, what your chosen configuration looks like or the optional extras you want, shade sails are a breeze to install. That’s not to say anybody can do it; correct installation of a shade sail requires carefully plotted and highly secure mounting points, as well as the right shade sail foundation. This is to ensure that there is adequate tension applied to the sail so that it will maintain its shape and remain functional in all conditions.

With our experienced team of covered area experts handling the entire process from conception to completion, we’ll carry out your installation with maximum efficiency while causing minimum interruption to your normal working day. What’s more, we always clean up after ourselves and ensure your site is left clean and tidy so you can start enjoying your brand new shade sail from day one.
