Cassette floors are prefabricated floor sections that include flooring, joists or trusses, bracing, and bearing stiffeners that are designed and prefabricated in a factory, delivered to site, and lifted into place with a crane.
Lightweight cassette floors are often used in multi storey buildings. They can be designed and manufactured for specific projects; it is possible to manufacture different sizes and shapes, with set-downs for wet areas and specific openings to accommodate services such as air conditioning ducts.
The main advantages of using floor cassettes is the speed of construction, and once a cassette has been lifted into position, it is immediately available as a working surface.
LVL is cost-effective as top and bottom chords in long span floor cassettes.
