What are the advantages of aluminum garage doors (polyurethane injected)?
Aluminum doors (injected with urethane, 1 ¾''
thick doors) offer the advantage of being lighter (compare to a steel
door) and therefore tend to be easier on their opening mechanism. In the
long run, great savings can be made on maintenance costs since the
mechanism will last longer. Other advantage: high resistance to salt
air. However, when it comes to doors measuring 3,6 m (12 ft.) wide or
less, there is little difference between aluminum and steel. Finally,
remember that aluminum is recyclable.
