Aluminum's benefits as a siding for houses are that it is lightweight, insulates and cools homes, resists rotting and insect infestations, does not rust, is fireproof and waterproof, does not grow mold and is easy to bend, which makes it easy to apply to horizontal and vertical surfaces. Aluminum siding, say authors at the International Association of Certified Home Inspectors, or interNACHI, is used less frequently as a housing material than other substances, but nevertheless provides some distinct advantages.
One trait that sets aluminum siding apart from other housing materials, say authors at interNACHI, is that it can be recycled. It requires minimal energy use for production, which makes it an environmentally friendly home insulation option. Aluminum is also a good insulator; it retains heat in the winter and holds cool air in the summer, which in turn reduces heating and cooling costs. Aluminum also has a long lifespan; it does not bend or crack, which makes it able to withstand temperature extremes and harsh conditions.
People in many environments use aluminum, but it is particularly useful in coastal climates and cold locales. Aluminum resists rust and corrosion, which makes it capable of weathering salt and moisture from coastal waters without sustaining damage. It does not swell or rot, and unlike vinyl does not crack in the winter, which reduces home repair costs.
Aluminum also comes in many colors and sizes. Homeowners can purchase aluminum in factory colors or paint it themselves. Some aluminum is made to resemble other housing materials, such as wood.
