Need a Quiet Door? Look for These Features
If you have an attached garage and want to minimize the racket caused by the garage door going up and down, choose a door with polyurethane insulation and nylon rollers. The insulation dampens any vibrations that would normally be amplified by an uninsulated steel door. And nylon rollers are simply quieter than metal ones. If you're also planning to replace the garage door opener, look for an opener with a belt drive. They're quieter than other types.
Choose 24-Gauge Steel
If you're going to buy an uninsulated steel door, make sure it's made from steel that's at least 24-gauge. Many economy garage doors are made from 25-gauge or thinner steel (the bigger the number, the thinner the steel). Insulation helps reduce denting by providing a backer for the steel. Without this reinforcement, you need thicker steel to prevent dents.
