Infill walls are lightweight, high durability, resistant to fire, ensure excellent thermal insulation and soundpenetration. Also they require less maintenance. A wide variety of materials or combinations of materials can be employed such as timber, steel, aluminium and plastic. Usage of any prefabricated components, including infill walls, wall parts, floor components, roofs, trusses etc., allows to decrease construction costs and time required compared to building on-site. Prefabricated wooden components are relatively light and can be erected at any heights using simple lifting equipment, like mobile cranes, in some cases with the cranes fitted on the trucks that deliver the components to the site.
