Garage Door Materials Compared: Steel, Wood, Aluminum and Fiberglass
The material of a garage door affects how it looks and how much care it needs. It also affects weight. Weight matters because springs and the opener have to lift it. This guide compares the common choices.
Steel
Steel is a very common choice. It is strong and comes in many styles. A steel door can dent. Scratches can lead to rust if left alone. Many steel doors have insulation built in. Read garage door rust causes and prevention.
Wood
Wood gives a classic look that suits many older New England homes. It needs more upkeep. Paint or stain must be maintained. Wood is usually heavier. It can swell and shrink with the weather.
Aluminum
Aluminum doors are light. They are often used with glass panels for a modern look. Aluminum can dent more easily than steel. Glass panels also affect privacy and insulation.
Fiberglass
Fiberglass resists rust. It is lighter than wood. Finishes can fade in strong sun. Quality varies between products.
| Material | Upkeep | Weight | Good to know |
|---|---|---|---|
| Steel | Low | Medium | Can dent and rust if scratched |
| Wood | Higher | Heavier | Needs regular finishing |
| Aluminum | Low | Lighter | Often used with glass |
| Fiberglass | Low | Lighter | Check finish and sun fade |
Weight and springs
A heavier door puts more load on the springs. A door must be balanced for its weight. A new door usually needs springs sized for it. Read what a balance problem looks like and how long garage door springs last.
Insulation and winter
Insulation helps comfort and noise. It also adds weight. Read insulation R-value explained.
