Why Belt Drive Is Quieter
Chain drive uses a metal chain on a metal track — metal-on-metal contact creates noise. Belt drive uses a rubber-reinforced belt on a smooth track — no metal contact, dramatically quieter.
The 10-15 dB difference is perceived as roughly half as loud. In a bedroom directly above an attached garage, this means you don't hear it open at 11 PM when someone gets home.
Why Chain Drive Lasts Longer
Steel chain doesn't wear out — it just needs lubrication. Rubber belt eventually frays after 15-20 years.
For detached garages, frequently-used heavy doors, or single-story homes where noise doesn't matter: chain drive is the more durable, cheaper choice.
Which Should You Buy?
Buy belt drive if: garage is attached with bedroom above, you open the door at all hours, you want zero maintenance.
Buy chain drive if: garage is detached, single-story home, budget-conscious, OK with annual lubrication.

Will chain drive wake me up?
If garage is attached with bedroom above and you operate at night: probably yes. Belt drive solves it.
Belt drive maintenance?
None — belt is sealed. Chain drive needs annual silicone lubricant.
