Solid aluminum: the safe alternative
Aluminium itself is a non-combustible material with good thermal conductivity. It is only when combined with flammable materials such as a polyethylene core or a wet paint finish that aluminum claddings can pose a fire hazard. Solid aluminum cladding is usually made from extruded, powder-coated aluminum, which dissipates heat, and if it is exposed to fire for a long period of time it will melt, not burn, preventing the spread of flames.
Powder coatings will also only char, again keeping flames from moving rapidly across the surface. Solid aluminum contains no combustible materials or core and is, therefore, a far safer cladding option for residential buildings. On top of this, solid, powder-coated aluminum has the added advantage of being a flexible, lightweight, and corrosion-resistant cladding type.
