The height at which you install your awning is very important. The right height ensures your awning works well, looks good, and provides the best shade and sun protection.

This article will explain the key points to consider when choosing the height for your awning, such as necessary clearance, proper angle for rain runoff, and adjustments for different heights. We will also show you how to measure correctly to make sure your awning fits perfectly.

Read on to learn the essential tips for setting your awning at the right height so it functions well and enhances your outdoor space. Understanding these factors will help you get the most out of your awning.

Measuring for Awning Installation

Height Measurement

Using the 3/12 pitch rule helps determine the best height for your awning. For every 12 feet of projection, the awning should drop by 3 feet. This ensures proper water drainage and optimal shade.

And if you're wondering, what is the suggested minimum height for awning installation? For patios or decks, the bottom of the awning should be at least 7’6” from the patio floor. For doors or windows, the awning should be 10-12 inches above the frame.

A proper pitch ensures rainwater flows off the awning, preventing water buildup and damage.

Width Measurement

Measure the horizontal length of the wall where you plan to install the awning. Ensure you measure across any gutters. Add 5 inches on each side of the measured width for a better fit and to ensure the awning covers the desired area effectively.

Ensure there are no downspouts, pipes, or other obstructions that could interfere with the awning installation.

Projection Measurement

Decide how far you want the awning to extend from the wall. Common projection sizes range from 5 to 14 feet. Consider the direction your patio or deck faces. For example, a West-facing area may need a longer projection for better shade.

You can add a Valance Plus retractable valance for extra shade when the sun is low. This feature can be particularly useful for West-facing patios or decks.

Determining the Ideal Awning Mounting Height

Factors Influencing Mounting Height

The ideal mounting height for your awning depends on two main factors: the required leadrail height and the desired pitch. The leadrail height is the height needed to walk under the awning when it’s fully extended.

The desired pitch, or angle, of the awning, ensures proper water runoff and optimal shading.

European Directive EN13561: Pitch Requirements

According to European Directive EN13561, a minimum pitch of 14 degrees is necessary for proper rainwater runoff. This means for every metre of projection, the awning should drop 25 cm in height. This pitch ensures effective drainage and extends the awning's lifespan.

Recommended Mounting Heights Based on Projection

Based on a 14-degree pitch, the recommended mounting heights are as follows (1):

• 1.50m projection: 2.38m
• 2.00m projection: 2.50m
• 2.50m projection: 2.63m
• 3.00m projection: 2.75m
• 3.50m projection: 2.88m
• 3.75m projection: 2.94m

Adjusting for Different Leadrail Heights

To adjust for different leadrail heights, add or subtract the difference from the standard mounting height. For example, if a 2.1m leadrail height is required, add 10 cm to the recommended heights:

• 1.50m projection: 2.48m
• 2.00m projection: 2.60m

Other Considerations

Consider obstructions like pipes, balconies, or single-story buildings that may impact the mounting position. Projections greater than 3.5m may require a steeper pitch to ensure adequate rain protection.

Larger awnings over 3.5m may not shed water as effectively, even with a good pitch, so plan accordingly.

What Is The Minimum Clearance For An Awning?

Minimum Clearance Needed

For awnings installed over patios or decks, a minimum clearance of 8 feet from the ground is essential. This height ensures there is ample space for people to move comfortably underneath the awning.

When installing an awning above doors or windows, it's important to maintain 10-12 inches of space between the top of the door or window frame and the awning. This clearance allows the awning to extend and retract properly without hitting the frame or blocking the view.

Importance of Unobstructed Space

It's crucial to have at least 6 inches of unobstructed space along the wall where the awning will be mounted. This space ensures that the mounting brackets and mechanisms have enough room to function smoothly.

Without this clearance, nearby structures or objects could interfere with the awning's operation, potentially causing damage or reducing its effectiveness. Keeping this space clear helps maintain the awning's performance and longevity.

Frequently Asked Questions

Is A Retractable Awning A Good Option For My Patio Or Deck?

Yes, retractable awnings are an excellent option for patios or decks. They provide adjustable shade, protect your outdoor furniture from the sun, and can even help lower indoor temperatures.

Additionally, retractable awnings can be retracted when not in use, giving you flexibility and control over your outdoor space.

My Wall Brackets For My Awning Seem To Be Too Low, What Can I Do?

If your wall brackets are too low, you may need to check for unobstructed horizontal space higher up the wall. Consider using roof mount brackets or beam brackets to achieve the proper height. Ensuring the correct mounting height is crucial for optimal awning performance and water drainage.

How Do I Find Out The Projection Of A Window Awning?

To determine the projection of a window awning, measure how far you want the awning to extend from the wall. Use a tape measure to mark this distance on the ground, keeping in mind any obstructions that might interfere with the awning's extension.

Typically, the projection should be sufficient to provide adequate shade and protection.

Do I Need To Measure The Awning Fabric When Determining The Width?

Yes, when determining the width, it is important to measure both the fabric width and the entire width of the awning frame. The fabric width is usually slightly less than the frame width, so accounting for both ensures a proper fit.

This will help you achieve the desired coverage for your space.

Are Soffit Brackets Necessary For Awning Installation?

Soffit brackets are not always necessary for awning installation, but they can be very useful in specific situations. They are ideal for mounting under an overhang or eave when wall space is limited.

Soffit brackets provide a secure and stable mounting option, ensuring your awning functions properly.

What Size Awning Do I Need For My Patio Or Deck?

The size of the awning you need depends on the area you want to cover. Measure the width of the space and consider the desired projection to ensure adequate coverage. Adding a few extra inches on each side can provide better protection and shade.

Is It Safe To Install An Awning Near An Electrical Outlet?

Yes, it can be safe to install an awning near an electrical outlet, but you must ensure the electrical cord is properly managed. Make sure the cord does not interfere with the awning's operation and is kept away from any water sources.

Always follow safety guidelines and consult a professional if needed.

Conclusion

In conclusion, selecting the right height and placement for your awning is crucial for optimal performance and longevity. By following the guidelines for measuring height, width, and projection, you can ensure your awning provides the desired mounting height and effective coverage.

Consider factors like unobstructed space and the specific needs of your patio or deck to achieve the best results. With the proper installation, your awning projects will enhance your outdoor space, providing shade, protection, and comfort.
