Shade sails add great value to businesses operating pools, parks or sports fields. However, some business owners hesitate to install these structures because they fear they will not withstand strong winds.
Our guide will explore how a shade sail’s design can offer optimal wind resistance. We’ll also discuss some installation techniques for improved stability in all weather conditions.
What Is a Shade Sail?
A shade sail is a piece of weatherproof fabric tensioned between one or more points. These structures shade businesses and public spaces, enabling people to make better use of outdoor areas. The space available will determine your sail shape and size. In addition, businesses have the option to customize the sail’s color and pole length for a unique design.
Once a professional team has installed the shade sail, they are easy to maintain. Your business can then enjoy benefits such as increased ultraviolet (UV) protection, cooler temperatures and enhanced use of space for years to come. Using a bespoke design or color also helps to boost the aesthetic value of your premises.
Understanding Shade Sails and Wind Resistance
Shade structures come in various shapes and sizes, allowing business owners to select the best design for their space and to withstand weather conditions like strong winds.
Shade structures offer many benefits to businesses, such as increased space, lower energy costs and improved comfort. Since shade sails are exposed to various elements, correct installation and optimized design are a must.
Importance of Wind Resistance
Strong winds pose the biggest threat to improperly installed shade sail structures. Here are three reasons why you should optimize shade sails for maximum protection:
- Flapping: Intense winds can cause the fabric to flap, increasing wear and tear. The anchor points may also become damaged with excessive movement.
- Tearing: If the sail’s design is not suited to withstand strong winds, it could tear and cause costly repairs. In addition, you will not gain the benefits of the structure during the repair period.
- Instability: Sails installed incorrectly could collapse and injure people. If the structure’s purpose is to cover equipment, these components may become damaged.
Which Areas of the United States Experience Extreme Winds?
Some parts of the United States — such as the Southwest and Pacific Coast — are at higher risk of rain, storms and high winds. Similarly, areas along the coastline are more prone to severe weather conditions. However, research indicates that global warming is altering weather patterns. A greater amount of inland states are now experiencing damaging winds, causing business owners to relook at the durability of their structures.
Business owners operating in both established locations and new areas should keep updated on weather trends. Seeking information from reliable sources, such as the National Oceanic and Atmospheric Administration and the Environmental Protection Agency’s storm surge inundation map, helps you make informed decisions.
If your organization is located in an area where wind may be a concern, a strong shade sail design is essential.
Do Shade Sails Hold Up in Wind?
The short answer is yes. However, consider the conditions in your area and choose a shade design carefully. Ensure proper tensioning and anchoring for structure stability. Regular maintenance will also help your shade sail stand up against robust winds. Periodically check the posts and hardware for signs of corrosion that may impact the sail’s wind resistance for peak longevity.
Design Variations for Enhanced Wind Resistance
Engineering teams have altered shade sail designs to ensure maximum wind resistance. Two ways they’ve achieved this include:
- Arched or dome shapes: Curved shapes allow wind to flow over the surface rather than pushing against it directly. Choosing an arched or domed structure helps to reduce drag, which could lead to damage.
- Tensioned canopies: A tensioned canopy design can help maintain shape and stability against wind forces. A canopy that retains its shape is able to prevent rain and UV rays from filtering through the mesh. In addition, it will stand up to strong winds, making these structures a good option in high-velocity winds.
The sail’s design plays a crucial role in wind resistance — yet business owners can further optimize its stability with height variation. Positioning the sail’s points at multiple heights results in the fabric corners sitting at various levels. Ideal height variation ensures better tensioning, which prevents flapping in high winds and potential damage.
Types of Shade Sails
There are various types of shade sails, each suited to different spaces and applications. Here’s an overview of the most popular shade sails for high-wind areas:
- 3-point sail: This option is compact in size, making it ideal for smaller areas. Businesses and schools often use 3-point sails to create shaded meeting or picnic areas.
- 4-point hypar sail: The expansive hyperbolic shape of 4-point hypar sails provides adequate cover for outdoor areas. Businesses can also select adjustable columns to accommodate tall structures beneath the sail.
- 5-point sail: If you’re looking to shade a larger area, 5-point sails are your solution. Each point is adjustable, enabling you to customize your structure for maximum ultraviolet (UV) protection.
- Cantilever hypar sails: Some outdoor areas have minimal mounting space, making cantilever hypar sails a good choice. High-end apartment buildings and recreational facilities benefit from these structures.
Finding the right sail for your area will help your business ensure optimal energy efficiency, space maximization and protection from the elements.
Material Selection
Selecting the right materials for a shade structure helps to ensure its durability. Common components include fabric, steel, wood or wood composites. While wooden frames offer aesthetic and insulation benefits, steel frames ensure superior stability in various weather conditions.
There are two fabric options renowned for their durability — Colourshade® and Shadesure®. Both these options comprise of high-density polyethylene (HDPE) mesh that effectively blocks approximately 97% of UV rays. In addition, they carry an extensive manufacturer’s guarantee to protect the shade solution against significant fading, deterioration, breakdown, mildew and extreme heat or cold.
When choosing shade structure materials, it’s best to consider the following aspects:
- Location and climate: Different regions experience varying levels of sun, rain and wind. Consider the weather patterns where your business operates to inform your material selection.
- Aesthetics: Shade structures stand out in any landscape. Choosing a powder coating finish and HDPE mesh in colors that match your brand also helps reinforce your business’s image.
- Budget: High-quality materials often come at a higher price point, yet they offer greater longevity. If your premises experience extreme weather conditions, it’s worth investing in more durable materials from the start.
Reinforcements and Additions
While it’s paramount that your business prioritizes a high-quality fabric and proper installation for your shade sail, there are a few ways to make it even more durable. These include:
- Double-stitched seams: Providing an additional seam will help prevent the fabric from fraying at the edges. Maintaining the solidness of the fabric will provide better resistance against the wind.
- Reinforced corners: Adding a layer of fabric to the corners ensures extra strength — this is particularly helpful if your business uses a cable system connected to the corners.
- Sturdy poles: Select poles made from durable materials, such as steel. Ensuring a sturdy frame will provide extra strength to the structure.
Best Installation Techniques for Windy Areas
Once your business has chosen the appropriate sail for your space, a team of professionals can begin the installation process. Discover some top techniques to enhance the structure’s stability in windy areas.
Select Your Location
Businesses can help reduce wind’s impact on their shade solution by considering its placement. For example, it’s preferable to install it near other buildings or natural elements such as trees to provide a windbreak. Open fields or large bodies of water will expose the structure to stronger winds, so it may be best to avoid placing your structure in these locations.
If your business is restricted on where to place the sail, then another idea is to create windbreaks by building low walls or planting vegetation. The type of soil at your location will also impact the stability of your shade sail. Working with a professional team will help businesses decide whether they require a base plate, recessed base plate or embed mounting component to secure your sail onto the ground.
Proper Anchoring Methods
The height and location of your anchors play a crucial role in your sail’s stability. Here are some common anchor types for a more robust installation:
- Ground anchors: These anchors are ideal for soft surfaces. Installers will screw them into the ground, enabling your posts set up to remain secure.
- Concrete footings: As an additional stability measure, teams can pour concrete into the post holes. This will help prevent them from shifting during gale-force winds.
- Post anchoring: Take care to select a structure with strong posts. Steel posts are a great option and will act as a robust anchor for your fabric.
- Wall mounts: If you’re using a cantilever structure and plan to attach it to your wall, you will need a wall mount. These contain heavy-duty brackets and bolts for enhanced strength.
Optimal Tensioning
Tensioning refers to stretching the fabric across two points. Optimal tensioning prevents the fabric from flapping in the wind, potentially resulting in wear and tear. Ahead of the tensioning process, your business may need to gather the following materials:
- Turnbuckles: These components assist with tightening the cables attaching the fabric to the frame.
- Ratchet straps: A ratchet strap is a fastener, allowing you to ensure consistent tension.
- Cable systems: Installers can use stainless steel cables to enhance the stability of the structure during tensioning.
- Anchoring hardware: Ground and post anchors are necessary for securing the frame to the surface.
Once installers erect the frame, they can place the fabric in position. An expert installer will begin by slightly tightening the cable on one corner and then moving to the next. Equal tensioning on all corners to allow for even stress distribution. Tensioning is an ongoing process. It’s a good idea to appoint someone to adjust tensioning on windy days and conduct a visual inspection after severe weather.
Professional vs. DIY Installation
When it comes time to install a shade sail, businesses have two options — tasking the job to a professional or a do-it-yourself (DIY) installation. Expert options are always best. A DIY project too often leads to expensive repairs and replacements later on.
Here are some key benefits of a professional installation:
- Compliant with regulations: Shade structures must comply with local building regulations. A professional team will be knowledgeable about the required permits and assist you in obtaining them.
- Customized to your area: A professional team can examine the local soil and make informed anchoring decisions. In addition, they can conduct wind load calculations to ensure your design can withstand them.
- Improved health and safety: An incorrectly installed shade structure is a significant safety risk. Using a certified team gives you greater peace of mind.
- Time efficiency: Professional teams have the equipment and knowledge for seamless installation. This makes the process quick and simple.
- Maintain your warranty: Shade sails typically have a warranty on the structural integrity of posts and fabric. Warranties are only valid if an approved installation professional tackles your project.
