Neither is better for everyone. Composite suits traditional and woodgrain styles at a lower cost with good insulation, while aluminium suits slim, contemporary looks and large glazed doors and is generally longer-lived. Both can reach high security ratings, so style, budget and exposure should decide.
How do aluminium and composite doors compare?
| Factor | Composite | Aluminium |
|---|---|---|
| Look | Traditional, woodgrain options | Slim, modern lines |
| Strength | Strong skin over insulated core | Very strong, allows slim sightlines |
| Lifespan | Often quoted at 25 to 30 years or more | Often quoted at 40 years or more |
| Upkeep | Wash and service hardware | Wash and service hardware |
| Cost | Generally lower | Generally higher |
Which is better in strong sun?
Aluminium does not warp, while a dark composite door can move in strong sun. A lighter colour or reinforced core reduces that risk for composite.
Which should you choose?
Choose composite for a traditional front door and a tighter budget, and aluminium for a modern home or a lot of glass. Check the lock and certification on either.
