Aluminum is one of the metal sidings. It is more popular than steel
because exposed areas of steel tend to rust. Aluminum siding comes in long panels with baked-on enamel finish that can be
smooth or textured. Aluminum may dent and depending on how high or low the damaged panel is replacing it may be difficult.
Aluminum is a good heat insulator and is very waterproof. Aluminum is composed of the same 3 basic parts as vinyl.
