Although still not as common a choice as other metals, aluminum vent covers are becoming an increasingly popular option for today's remodelers and home builders. The popularity of aluminum heats registers and return air grilles can be attributed to three advantages over vent covers with brass, bronze and cast iron grilles:
The most obvious advantage of vent covers with aluminum grilles is that they are much lighter than vent covers with cast brass, bronze and iron grilles. This makes aluminum grilles logical choices for wall and ceiling applications. However, vent covers with aluminum grilles are also suitable to be used as floor vent covers with a few exceptions. Aluminum is not offered in extra large sizes and therefore not an option for extra large air returns. Additionally, aluminum grilles are not recommended for floor vent covers that will potentially endure a lot of foot traffic as their painted surfaces can scratch.
Aluminum heat registers and grilles are also an excellent alternative to cast iron in areas where the vent cover will be exposed to moisture like bathrooms and exterior applications. Quality aluminum and cast iron grilles have durable powder coat finishes, however, aluminum will not rust if the powder coat finish becomes worn or damaged like cast iron might.
Cost is often a key concern of those shopping for decorative vent covers and price has attracted many to choose aluminum grilles. Aluminum heat registers and grilles are generally considerably more affordably priced compared to their cast brass, bronze and aluminum counterparts. Including aluminum grilles as a substitute for cast iron or bronze grilles will reduce the total cost of your project while maintaining the desired consistent look among your floor, walls and ceiling vent covers.
