With multiple attachment points, these sails ensure sturdy installation and can be customized in size and color to fit various architectural styles and project needs.

Twisted (Hypar Designed) Shade Sails

A hyperbolic paraboloid shade sail (“hypar” for short) is a dynamically curved design that optimizes tension and water-shedding capabilities across its fabric. 

Creating dynamic height variations in shade sails enhances their visual appeal and serves practical purposes. 

Varying the attachment points' heights helps water shedding, preventing pooling and weight accumulation on the sail. 

This design, known as a hyperbolic parabola, features alternating high and low points to maintain tension across the fabric. This configuration minimizes sagging and eliminates flapping in the wind. 

Tenshon recommends a height variation ratio of 5:1 (meaning for every 5’-0” horizontal, increase the rise by 1’-0”), ensuring optimal performance and durability for shade sails spanning different distances. 

Even for three-sided sails, adjusting heights effectively reduces sagging by directing water towards attachment points rather than the center, ensuring efficient functionality and aesthetic appeal.

Design Considerations

Material Choices

High-density Polyethylene (HDPE) is the product of choice when creating a shaded space. Offering up to 95 % UV protection, HDPE is known for its strength and longevity, making it a durable and resilient fabric for long-term sun exposure. 

Due to its knit construction, HDPE fabric can be tensioned into place to create a beautiful form and eliminate sagging. Additionally, heat can rise through the shade material, rather than be trapped like under a steel ramada, allowing for a solution that offers both sun protection and a cooler space.

We work with a range of high-quality knitted HDPE fabrics, each graded for commercial or architectural use, so we can match the right material to the size and scope of your project.  

Color Options

When looking to deck out an outdoor space, you need to choose the best shade sail for the job, but choosing the right color is about more than good looks. Color significantly affects your shade sail project’s functionality and appeal. 

Lighter colors reflect more sunlight, reducing heat absorption and providing a cooler area underneath, but may result in more glare and less visibility through the material. 

Darker shades absorb more UV rays and heat, offering better protection and reduced glare, making them preferable for areas where sun protection is a priority.

Take a look at our available color selections.

Structural Support

The design of the support structure is crucial for the durability and effectiveness of shade sails. 

Utilizing a hypar shape (involving alternating high and low fixing points) increases tension and reduces flapping, extending the sail's life. Height variation in the attachment points adds visual interest and aids water runoff.

Additionally, ensure the attachment points are structurally sound, especially when mounting to existing buildings, to handle the lateral forces exerted by the sails. 

For larger installations, consider the use of thick-walled steel poles and secure concrete footings to support the substantial forces involved.

By carefully considering these design elements, you ensure not only the functionality of your shade sails but also enhance their contribution to the overall aesthetic of the space.

Consider Sun Exposure for Optimal Shade Sail Placement

When picking a spot for your shade sail, sun exposure is a critical factor. Look for an area that gets plenty of sunlight but doesn't become too hot. Be mindful of how the sun moves throughout the day, as the direction and intensity of sunlight can vary.

Understanding sun angles is also key. In summer, the sun sits higher in the sky, casting more direct light. In winter, it’s lower, providing more indirect light. 

By factoring in the sun's position and the time of year, you can choose the best location for year-round comfort and effective shading.

Optimize Your Shade Sail Placement for Maximum Comfort

Where will people spend the most time? Identify high-traffic areas in your design and location as prime spots for shade structures. Shade attracts people, so think about where you want visitors to gather. 

Adding shade near seating areas, pathways, or activity zones encourages people to use these spaces even when the sun is intense. Placing shade in popular gathering spots makes these areas more comfortable and inviting, enhancing the overall experience for your guests.

Installation

While some smaller shade sail systems can be installed by skilled DIYers, custom or commercial-grade projects typically require the expertise of a licensed contractor to ensure structural integrity and code compliance. 

This knowledge not only helps in planning but ensures the installation process is smooth and the final structure is secure and durable. 

Proper installation is key to maximizing the lifespan and effectiveness of your shade sail, ensuring it stands up to the elements and provides optimal shade and comfort.

FAQs for Designing with Custom Shade Sails

1. What considerations are important when designing shade sails?

When designing shade sails, several factors are critical to ensure optimal functionality and longevity. Firstly, avoid having the shortest side of a shade be less than half of the longest side, as narrow sails are prone to sagging and instability. 

The angle of the sail is equally important; designs like triangles or flat shade sails should have a sufficient slope to prevent rainwater from pooling, which can lead to fabric damage and structural failure. 

We also recommend having our shades be no less than 5’-0” directly above anything that can poke or damage the shades. 

When designing over playground equipment, playground safety standards dictate that the shade should be no less than 7’-0” above a standing platform or deck.  

Consider the environment and climate where the shade sail will be installed. Ensure the design allows for adequate airflow to prevent heat buildup and includes UV-resistant materials for maximum sun protection. 

Proper tensioning of the sail is essential to maintain its shape and prevent wear. The choice of materials, color, and structural support should align with the overall aesthetic and functional requirements of the space.

2. How should I select the shape of a shade sail?

Selecting the shape of a shade sail depends on the specific coverage needs and the design aesthetics of the space. Triangle shade sails are versatile and effective for smaller areas, but multiple sails might be required for larger coverage. 

Rectangle and square sails provide extensive coverage and are ideal for larger areas like patios, pools, or playgrounds.

Consider the site's layout and any existing structures that might influence the sail's design and placement. 

Each shape has unique benefits; for instance, triangle sails offer flexible configurations and aesthetic appeal, while rectangular sails ensure broad coverage and structural stability. 

The shape should also complement the architectural style and intended use of the space, enhancing both functionality and visual impact.

3. Are shade sails waterproof?

Shade sails are made from high-density polyethylene (HDPE) fabric, which is water-resistant but not entirely waterproof. This material is designed to withstand mold and water damage, making it durable in rainy conditions. 

However, due to its breathable nature, HDPE allows small amounts of water to pass through, especially if water pools on top. 

Properly sloping and layering the sails can improve water deflection and prevent pooling, enhancing their performance in wet weather.

4. What about weather and wind?

Shade sails are crafted from strong fabric and, when properly tensioned, can endure typical weather conditions for years. 

However, it is advisable to take them down in the event of unusually high winds or snow. Accumulated snow can overstretch the sail, causing it to lose tension and effectiveness.

Engineering specifications, including wind ratings, should be adhered to for safety and durability. The anchor points are crucial; they must be sturdy enough to support the sail. 

Weak anchor points, like undersized posts or poorly placed eye bolts, can fail even if the fabric remains intact. Always ensure the installation is robust to maximize the sail’s lifespan.

5. How long will my shade sail last?

The lifespan of a shade sail can vary based on several factors, including tension, environment, and weather conditions. Ensuring the sail is properly tensioned and maintained can prevent premature wear and extend its life. 

Generally, well-installed and maintained shade sails can last between 5-7 years, though many can exceed this timeframe, continuing to provide effective shade for up to a decade. 

Regular inspections and adjustments are recommended to keep the sail in optimal condition.
