This article will delve into the intricacies of torsion springs, focusing on what you need to know to make an informed decision about your garage door’s spring system.

2. Basics of Torsion Springs in Garage Doors

What is a Torsion Spring?

A torsion spring is a type of spring that is wound tightly to store mechanical energy. When the garage door is operated, the torsion spring unwinds and releases this energy to lift the door. As the door moves up, the torsion spring coils tighten, storing potential energy. When the door is lowered, the spring unwinds, releasing the stored energy to help lower the door.

Torsion Springs vs. Extension Springs

Torsion springs and extension springs serve similar purposes but operate differently.

• Torsion Springs: Mounted above the garage door, torsion springs are attached to a metal shaft. They provide a smooth lifting action by evenly distributing the door’s weight across the spring. This results in less wear and tear on the door’s components and a quieter operation.

• Extension Springs: These are mounted on either side of the door and stretch as the door opens. While they are less expensive than torsion springs, they can be noisier and may require more frequent adjustments. Extension springs also tend to be less durable and may wear out more quickly than torsion springs.

Why Torsion Springs are Preferred

Torsion springs are generally preferred for residential garage doors due to their superior performance. They offer:

• Smooth Operation: Torsion springs provide a smoother, quieter door operation compared to extension springs.

• Durability: They are designed to last longer and handle heavier weights, making them ideal for larger and heavier doors.

• Safety: Torsion springs are mounted high above the door, reducing the risk of injury compared to extension springs, which can snap and cause injury if not properly maintained.
