How to stop a motorhome awning from flapping


Best Awning Storm Straps For Motorhomes & Campervans

Have you ever tried enjoying a quiet evening by your motorhome, only to be interrupted by the incessant flapping of your awning? It’s a common issue many motorhome enthusiasts face. But why does it happen, and how can we stop it? Let’s delve into the nitty-gritty of how to stop a motorhome awning from flapping.

Understanding the Issue

Motorhome awnings serve as a functional extension to our vehicles, offering shade and protection against elements like rain or sun.

Our awning has been a life saver to us whilst travelling around hot countries like Spain and Portugal in our motorhome, without it, we would really have struggled.

However, like any other outdoor equipment, they’re exposed to various external conditions which, when combined with factors like material and installation, can lead to the frustrating issue of flapping.

Delving deeper into understanding the causes and implications of this can offer insights into effective prevention and management.

Why awnings flap

Awning flapping is more of a science than a random act of nature. At the heart of this issue are the dynamics between the fabric of the awning, its frame, and the external environment.

  1. Aerodynamics: As the wind flows around your motorhome, it encounters resistance, especially with added structures like awnings. The wind doesn’t just hit the awning directly; it swirls around it, causing lift and turbulent flows which, when strong enough, result in the flapping motion.
  2. Material Flexibility: Most awnings are made of lightweight, flexible materials. While this makes them easy to install and retract, it also means they are more susceptible to being manipulated by forces like wind.
  3. Loose Areas: Over time, awnings can develop loose areas due to stretching, poor retraction practices, or damage. These loose parts act like sails, catching even the slightest breeze and initiating the flapping.

Why it’s important to stop your awning from flapping

Beyond the annoyance, continuous flapping can lead to more severe consequences:

  1. Wear and Tear: Continuous flapping strains the material, leading to faster degradation. Over time, this weakens the awning, making it more prone to tearing.
  2. Structural Damage: The repetitive force from the flapping can damage the mounting brackets or the side of the motorhome where the awning is attached.
  3. Safety Concerns: A wildly flapping awning can pose safety risks. Loose parts can detach and fly off, potentially injuring someone or causing property damage.
  4. Reduced Efficiency: The primary role of the awning is to provide shade and shelter. An awning that’s constantly flapping fails to fulfil this role efficiently, making outdoor spaces less comfortable.

The cost of having to repair and potentially replace your awning is something you just don’t need, luckily there are measures that you can put in place to help with this problem.

How to stop a motorhome awning from flapping – prevention tips

Preventing your motorhome awning from flapping starts long before the first gust of wind hits. By incorporating preventive measures during installation, maintenance, and daily use, you can significantly reduce the chances of your awning flapping and reduce the risk of damage. Here are some more detailed prevention methods to consider:

Proper Installation

  1. Level Mounting: Ensure that the awning is mounted evenly. Any slant or angle can create pockets where wind can catch, leading to flapping.
  2. Tight Seals: When attaching the awning to your motorhome, ensure all seals and brackets are tightly secured. A loose mount can result in more movement and, by extension, more flapping.
  3. Professional Help: If you’re unsure about the installation, don’t hesitate to get a professional. They’ll have the experience and tools to ensure a snug fit.

Regular Maintenance

  1. Cleanliness: A clean awning is less likely to have weakened spots. Regularly cleaning off dirt, bird droppings, and other debris prevents them from becoming ingrained and eroding the material.
  2. Inspect for Damage: Over time, wear and tear are inevitable. Look for weak spots, holes, or areas where the fabric seems thinner. Addressing these early can prevent bigger problems later on.
  3. Lubricate Moving Parts: Awnings have several moving parts, especially retractable ones. Ensure they’re lubricated so they move smoothly without straining the fabric or mechanisms.

Correct Tension

  1. Balanced Tension: It’s crucial to strike a balance. Too much tension can strain the fabric and fixtures, while too little leaves slack that can flap. Adjust until the awning feels taut but not overly stretched.
  2. Retraction Practice: When retracting your awning, ensure it rolls up evenly. Uneven retraction can lead to areas of slack when it’s extended again.
  3. Regular Adjustment: Over time, the tension of the awning can change due to various factors like temperature fluctuations or prolonged use. Regularly adjust to maintain optimal tension.

Additional Precautions

  1. Weather Forecast: Before setting up your awning, check the weather forecast. If strong winds or storms are predicted, it might be best to keep the awning retracted.
  2. Retract When Away: If you’re going away from your motorhome, even for a short duration, consider retracting the awning. This ensures that sudden gusts of wind don’t catch you off guard.
  3. Use Side Panels: These panels act as windbreakers, reducing the force of side winds that can cause the awning to flap.

By regularly implementing these prevention tips, you can enjoy the benefits of your awnings without the nuisance and risks associated with flapping. Remember, proactive care often saves time, money, and frustration in the long run.

Quick Fixes on the Go

Sometimes, despite our best prevention efforts, we find ourselves faced with a flapping awning while out on a trip. Whether it’s an unexpected gust of wind or an oversight in setting up, having a few quick fixes up your sleeve can be invaluable.

Using Awning Straps

  1. Ground Anchoring: Awning straps are essentially tie-downs. Attach one end to your awning and the other to a sturdy point on the ground. This gives the awning additional stability against the wind.
  2. Adjustable Length: Look for straps that are adjustable. This allows you to determine the tension, ensuring that it’s tight enough to reduce flapping but not so tight that it strains the awning.
  3. Positioning: Placing straps at intervals across the width of the awning can distribute tension evenly, preventing any particular section from flapping.

De-Flapper Tools

  1. Clamping Action: De-flapper tools are designed to clamp onto the awning fabric, adding weight and reducing movement. Their primary purpose is to ‘pin down’ sections of the awning that are prone to flapping.
  2. Versatility: Many of these tools are adjustable to fit different awning thicknesses and materials, ensuring a firm but non-damaging grip.
  3. Placement Strategy: For best results, observe which parts of the awning flap the most and attach the de-flappers there.

Stabilising with Weights

  1. Weight Choices: While there are specially designed awning weights, in a pinch, you can use sandbags, bags filled with rocks, or even heavy bottles.
  2. Hanging Points: Attach weights to the front rail or the end corners of the awning. This downward force can counteract the lifting effect of the wind.
  3. Even Distribution: Ensure weights are distributed evenly to avoid putting undue strain on one part of the awning.

Temporary Side Screens

  1. Break the Wind: By attaching screens or panels to the sides of your awning, you create a barrier against lateral winds which are often responsible for intense flapping.
  2. Fabric Choices: Use breathable fabrics to ensure the wind doesn’t catch the screens themselves. Mesh screens can be particularly effective.
  3. Easy Attachments: Velcro, ties, or clips can be used to attach these screens quickly without the need for any tools.

Retraction as a Last Resort

  1. Safety First: If the flapping becomes too intense and none of the quick fixes seem effective, consider retracting the awning. This ensures that neither the awning nor the motorhome suffers damage, and more importantly, keeps everyone safe.
  2. Partial Retraction: If you still require shade but want to reduce the awning’s exposure, consider retracting it partially.

Out in the great outdoors, where conditions can change rapidly, it’s always handy to have a few quick fixes ready.

Long-term Solutions

While quick fixes can address the immediate problem of a flapping awning, adopting long-term strategies ensures lasting and effective solutions.

By investing in these permanent measures, you can enhance your outdoor experience and reduce frequent maintenance costs.

Invest in Quality Awnings

  1. Material Matters: High-quality awnings typically use durable materials that resist wear and tear and are less prone to flapping. Consider fabrics like acrylic or heavy-duty vinyl, which offer a good balance of flexibility and rigidity.
  2. Retraction Mechanism: Awnings with robust retraction mechanisms ensure even roll-up and roll-out, preventing slack areas which can lead to flapping.

Install Wind Sensors

  1. Automated Response: Wind sensors detect strong gusts of wind and automatically retract the awning. This is particularly useful if you’re not around or inside the motorhome when a sudden storm hits.
  2. Adjustable Sensitivity: Some advanced sensors allow you to set the wind speed threshold, giving you control over when the awning should retract.

Use Permanent Side Screens

  1. Barrier Creation: Similar to the temporary screens, permanent side screens or walls offer a lasting solution to block side winds, significantly reducing flapping.
  2. Material Durability: Opt for materials that can withstand the elements, ensuring longevity and reduced maintenance.

Incorporate Additional Supports

  1. Support Rafters: These are additional bars or rods that can be attached to the awning to provide extra rigidity. They spread the tension across the awning, preventing any particular area from becoming a wind pocket.
  2. Centre Support: Adding a support beam in the middle of larger awnings can break up the space, reducing the surface area exposed to the wind.

Regular Professional Check-ups

  1. Scheduled Maintenance: Just like you’d get your motorhome serviced regularly, having a professional inspect and service your awning ensures its longevity. They can spot potential problems before they become severe and ensure all parts are functioning optimally.
  2. Upgrades: A professional can also advise on the latest technologies or upgrades that can be integrated into your existing setup to reduce flapping.

Proper Storage

  1. Protective Covers: When not in use, especially during off-season or prolonged periods, using protective covers can prevent damage due to UV rays, dust, and other environmental factors.
  2. Clean and Dry: Ensure the awning is clean and completely dry before storage to prevent mould and mildew, which can weaken the fabric and make it more susceptible to flapping.

Stay Updated on Weather Patterns

  1. Advanced Forecasting: Use weather apps or systems that offer real-time and accurate forecasts. This can allow you to anticipate and prepare for wind events.
  2. Climate Awareness: If you frequent certain locations with your motorhome, understanding the local climate can help in setting up the awning accordingly.

Implementing these long-term solutions provides a more relaxed and carefree motorhome experience. Though they may require a bit more investment upfront, the peace of mind and reduced repair costs in the long run are well worth it.


A motorhome trip should be about relaxation, not constant battles with a flapping awning. By understanding the root causes and implementing preventive and corrective measures, you can enjoy a flap-free experience.

So, the next time you’re out in the wild, remember these tips and enjoy a peaceful evening by your motorhome.
