The Differences Between Torsion and Extension Springs

Garage doors need springs to operate smoothly, and understanding the differences between torsion and extension springs can help homeowners maintain their garage door systems.

Garage doors need springs to operate smoothly, and understanding the differences between torsion and extension springs can help homeowners maintain their garage door systems. Both types of springs play a crucial role in lifting and lowering the door, but they function differently and have distinct advantages. Below is an overview of the key differences between torsion and extension springs and how they impact garage door performance.

Torsion Springs: How They Work

Torsion springs are installed on top of the garage door and mounted horizontally on a metal shaft. When the door is closed, these springs wind up, storing energy. When the door opens, the stored energy is released, helping lift the door. Torsion springs provide a controlled and balanced lifting force, allowing for smoother and more stable operation. They are known for their durability and can last for many years with proper maintenance.

Torsion springs are often preferred for heavier garage doors due to their strength. They distribute the door’s weight evenly, reducing strain on the opener and other components. Because they are located above the door, they also contribute to a cleaner and more organized appearance in the garage.

Extension Springs: How They Function

Extension springs are installed on the sides of the garage door and work differently from torsion springs. Instead of winding and unwinding, extension springs stretch and contract to lift and lower the door. When the door is closed, the springs are stretched, and as the door opens, they contract, using stored energy to assist in the lifting process.

Extension springs are usually utilized on lighter garage doors and are more common in older systems. They provide a strong lifting force but can create more bounce and instability compared to torsion springs. Although they are typically cheaper than torsion springs, they may wear out faster due to the constant stretching and contracting during use.

Durability and Lifespan

One of the primary differences between torsion and extension springs is their durability and lifespan. Torsion springs are designed to last longer, often providing 15,000 to 20,000 cycles before needing replacement. Their design allows for a slower wear rate, making them a more reliable choice for long-term use. Regular maintenance, such as lubricating the springs, can further extend their lifespan.

Conversley, extension springs have a shorter lifespan, typically lasting around 10,000 cycles. Because they undergo more strain due to constant stretching, they may require more frequent replacement. Garage professionals often recommend torsion springs for homeowners seeking a more durable and long-lasting solution for their garage door systems.

Safety Considerations

Both torsion and extension springs require careful handling, as they store a significant amount of energy. However, torsion springs are generally considered safer to use. Because they are held on a stationary metal shaft, they are less likely to snap or break unexpectedly. If a torsion spring does break, it remains contained within the shaft, reducing the risk of injury or damage.

Extension springs, however, can pose more safety risks. If an extension spring breaks, it can snap with force, potentially causing damage to property or injury. For this reason, extension springs are often outfitted with safety cables that run through the center of the spring. These cables help contain the spring in the event of a break. Homeowners with extension springs should regularly inspect the safety cables to guarantee they are intact and functioning properly.

Cost and Installation

In terms of cost, extension springs are generally more affordable than torsion springs. They are a common choice for budget-conscious homeowners or for those with lighter garage doors. However, while extension springs have a lower upfront cost, they may require more frequent upkeep and fixes over time.

Torsion springs, though more expensive initially, offer better long-term value due to their durability and reduced need for repairs. The installation process for torsion springs is more complex, often requiring the expertise of a garage door company to install and maintain them properly. Garage professionals can confirm that the springs are installed correctly and safely, helping to avoid potential issues in the future.

Performance and Smoothness of Operation

When comparing performance, torsion springs provide a smoother and more controlled operation. Because they lift the door evenly, they reduce wear on other garage door components, such as the opener and tracks. Torsion springs also minimize the jerking or bouncing motions often associated with extension springs, offering a quieter and more reliable operation overall.

Extension springs, while effective, can create more bouncing or swaying motions during operation, which can lead to instability. This issue can cause additional wear on the door and opener, especially over time. Homeowners looking for a more stable and balanced system often prefer torsion springs for their performance advantages.

Both torsion and extension springs have their place in garage door systems, and understanding the differences between them can help make the right choice for specific needs. Consulting a garage door company can provide expert guidance on which spring type is best suited for the door, guaranteeing optimal performance and safety.
