When it comes to keeping your home warm, secure, and free from unwanted drafts, many of us have resorted to a simple yet effective hack: placing a towel under the door. But does this age-old trick really work, or is it just a myth with no scientific basis? In this article, we’ll delve into the world of door drafts, explore the science behind the towel trick, and examine its effectiveness in various situations.
Understanding Door Drafts
Before we dive into the towel trick, it’s essential to understand what door drafts are and how they occur. A door draft is a flow of air that enters or escapes through the gap between the door and the floor. This gap, also known as the threshold, can be a significant source of heat loss in the winter and heat gain in the summer.
Door drafts can occur due to various reasons, including:
- Improper door installation: If the door is not installed correctly, it can leave gaps between the door and the frame, allowing air to escape or enter.
- Settling foundations: Over time, the foundation of your home can settle, causing the door to shift and create gaps.
- Worn-out door sweeps: The door sweep, also known as the threshold seal, can wear out over time, allowing air to pass through.
- Weatherstripping issues: Weatherstripping is designed to seal the gaps between the door and the frame. However, if it’s damaged or worn out, it can’t perform its function effectively.
The Science Behind the Towel Trick
So, how does placing a towel under the door help to reduce door drafts? The answer lies in the principles of air pressure and flow.
When you place a towel under the door, it blocks the flow of air through the gap, creating a barrier between the inside and outside environments. This barrier helps to:
- Reduce air pressure differences: By blocking the flow of air, the towel helps to reduce the pressure differences between the inside and outside environments, which in turn reduces the flow of air through the gap.
- Decrease convection currents: Convection currents occur when warm air rises and cool air sinks. By blocking the flow of air, the towel helps to decrease convection currents, which can contribute to heat loss.
Factors Affecting the Towel Trick’s Effectiveness
While the towel trick can be effective in reducing door drafts, its effectiveness depends on several factors, including:
- Towel material and size: A thicker, larger towel will be more effective at blocking air flow than a thinner, smaller one.
- Door gap size: The larger the gap, the less effective the towel will be at blocking air flow.
- Air pressure differences: If the air pressure differences between the inside and outside environments are significant, the towel may not be effective at reducing air flow.
- Door type and material: The type and material of the door can affect the towel’s effectiveness. For example, a towel may be more effective at blocking air flow under a wooden door than a metal door.
Alternatives to the Towel Trick
While the towel trick can be effective, it’s not the only solution to reducing door drafts. Here are some alternative methods:
- Door sweeps and threshold seals: Installing a door sweep or threshold seal can be an effective way to block air flow through the gap.
- Weatherstripping: Replacing worn-out weatherstripping can help to seal the gaps between the door and the frame.
- Door draft stoppers: Door draft stoppers are specifically designed to block air flow through the gap. They can be made of various materials, including foam, fabric, or metal.
- Adjusting the door: If the door is not installed correctly, adjusting it can help to reduce the gap and block air flow.
DIY Door Draft Stoppers
If you’re looking for a more permanent solution to reducing door drafts, you can create your own DIY door draft stopper using materials like foam, fabric, or wood. Here’s a simple DIY project:
- Materials needed:
- Foam or fabric
- Wood or PVC pipe
- Scissors or a saw
- Glue or nails
- Instructions:
- Cut the foam or fabric to the desired size.
- Cut the wood or PVC pipe to the desired length.

In conclusion, placing a towel under the door can be an effective way to reduce door drafts, but its effectiveness depends on various factors, including the towel material and size, door gap size, air pressure differences, and door type and material. While the towel trick can be a temporary solution, it’s essential to consider more permanent solutions, such as installing a door sweep or threshold seal, replacing worn-out weatherstripping, or creating a DIY door draft stopper.
By understanding the science behind door drafts and the towel trick, you can make informed decisions about how to reduce heat loss and keep your home warm and secure.
Additional Tips and Considerations
- Regular maintenance: Regularly inspect and maintain your doors and windows to ensure they’re functioning correctly.
- Seal other gaps: Don’t forget to seal other gaps and cracks in your home, including those around windows, electrical outlets, and switches.
- Consider professional help: If you’re not comfortable with DIY projects or if the issue persists, consider hiring a professional to inspect and repair your doors and windows.
By following these tips and considering the alternatives to the towel trick, you can keep your home warm, secure, and energy-efficient.
What is the purpose of putting a towel under the door?
Putting a towel under the door is a common technique used to block cold air, smoke, or odors from entering a room. The idea behind this method is that the towel will act as a barrier, preventing unwanted air or particles from passing underneath the door. This technique is often used in situations where a door sweep or weatherstrip is not available or effective.
In theory, the towel should be able to block the flow of air and particles by filling the gap between the door and the floor. However, the effectiveness of this method depends on various factors, including the type of towel used, the size of the gap, and the air pressure difference between the two sides of the door. In some cases, putting a towel under the door may provide a temporary solution, but it may not be a reliable or long-term fix.
Does putting a towel under the door really work?
The effectiveness of putting a towel under the door is a topic of debate. While some people swear by this method, others claim that it is nothing more than a myth. In reality, the success of this technique depends on various factors, including the type of towel used, the size of the gap, and the air pressure difference between the two sides of the door. If the towel is thick enough and the gap is small, it may be able to block some of the air or particles.
However, in most cases, putting a towel under the door is not a reliable solution. The towel may not be able to withstand the air pressure difference, and it may not be able to block all of the air or particles. Additionally, the towel may become displaced or damaged over time, reducing its effectiveness. Therefore, it is essential to separate fact from fiction and understand the limitations of this technique.
What are the limitations of putting a towel under the door?
