Abstract
A floor construction of wood panels (12) overlying a base support (11) with a layer (13) of yieldably resilient materials (14, 15) sandwiched between the panels (12) and the base support (11). The materials (14, 15) are of mutually different stillnesses, one being a relatively large main panel area of an open-cellular material (14) and the other being a relatively small area of a closed-cellular material (15) in the form of strips bordering the main panel area. The open-cellular material (14) provides a large degree of vibration isolation, whilst the closed-cellular (stiffer) material (15) stabilizes the panels in the vicinity of panel-to-panel joints and/or the floor periphery.
