The Alucobond PLUS naturAL Terra Series, featuring six textured finishes inspired by iridescent stone, has been released by 3A Composites USA. The aluminum composite material (ACM) line includes Arctic Frost, Clear Ice, Lava, Precast Grey, Sierra Sand and Terra Cotta finishes, designed to sparkle in daylight like iridescent stone but, because the panels are ACM, they are lighter weight and can be formed into unique shapes. Terra Series panels also are weather-resistant and color fast. Alucobond PLUS consists of two sheets of 0.020-inch aluminum thermobonded to a proprietary fire-resistant core. The wall panels have a flame-spread index of less than 25 and a smoke-developed index of less than 450 when tested in accordance with ASTM E 84. They also have achieved a Class A interior finish classification.
