Foamed concrete is typically made by mixing water, cement, and foam. It contains fewer chemicals and is a non-toxic, more environmentally friendly, and lightweight alternative to standard poured concrete. Its high air content and fire-resistant properties make it ideal for insulation, soundproofing, and filling those awkward gaps—old or unused pipes or spaces between bricks, for example. It is also used for structural elements, such as walls and floor slabs, and for interior buildings that aim to be more environmentally friendly.
