SUMMARY - Aluminum siding offers heat resistance and above-average durability. This type of siding originated in the 1930’s as a durable, low-maintenance alternative to wood siding. Although it has been surpassed by vinyl in terms of popularity, the current generation of aluminum siding still has a lot to offer. The paint is better, so the chalking and fading of early siding is no longer as prominent of an issue as it once was. Aluminum siding is a formed material, typically .019" thick. Aluminum siding has a baked on enamel finish, and if scratched, the paint will be removed and the bare metal below will be visible. However, due to the expansive properties of vinyl, aluminum siding takes paint better if you ever decide to re-paint. It is not recommended to paint vinyl. Aluminum Siding is available with both a textured or smooth finish. The upkeep is generally minimal, although it should be checked annually for dents and scratches. If you want a product that is resilient, works well through most weather conditions, and is resistant to heat, aluminum siding is an excellent choice.
