Modern house-construction techniques include light-frame construction and adobe or sometimes rammed-earth construction. Some areas use brick almost exclusively, and quarried stone has long provided walling. Increasingly popular alternative construction materials include insulating concrete forms (foam forms filled with concrete), structural insulated panels (foam panels faced with oriented strand board or fiber cement), and light-gauge steel framing and heavy-gauge steel framing.
