Composites are engineered or naturally occurring materials made from two or more constituent materials. They have significantly different physical or chemical properties that are predominantly used in the manufacture of building products. The market encompasses fiber type used in construction composites such as glass fiber, natural fibers, and other fibers that are used in the industrial, commercial, housing, and civil sectors. The construction sector offers an abundant potential for the use of composites since they significantly improve the product performance over traditional building materials. Some of the key composite applications in the construction sector include structural components, roofing, doors and window profiles, acoustics, cladding, and facades, in addition to customized fabrication of structures and components. The composites used in the construction sector are lightweight, durable, and offer flexibility to engineers, architects, and designers, to bring out innovative designs that are not constrained by material limitations.
