A flooring assembly comprising a flooring unit comprising a stability core layer having a plurality of edge surfaces, two of which have an interlocking mechanism for attachment to the edge surfaces of the stability core of adjacent flooring units; a sound attenuating acoustic layer attached to the bottom surface of the stability core layer; and a finish layer attached to the top surface of said stability core layer.

A construction and methods of assembly and construction of boards, e.g. floor boards, are described. The boards have a peripheral connection arrangement for interconnecting of one board to another, a core layer e.g. made from a wood or fiber based material and a top layer applied to the core layer which may be decorative and may include or provide a wear layer. A further bottom layer may be applied to the underside of the core layer and is designed to be in contact with the floor or an underlay can be applied when in use. The connection arrangement includes interconnecting hooking tongues and corresponding catches which co-operate to produce both vertical and horizontal locking.

A flooring system includes at least two discrete layers. The at least two discrete layers include at least a first discrete layer comprising variably responsive elastic subfloor. The at least a first discrete layer includes at least first sublayer having area elastic properties and at least a second sublayer, wherein at least a portion of the at least a second sublayer includes a first material displaying dilatant properties. The at least two discrete layers include at least a second discrete layer comprising a wear layer disposed on top of the at least a first discrete layer.

A flooring system is provided comprising a plurality of (identical) floor panels, which are mechanically connectable to each other along at least one pair of adjacent first and second opposite joint edges. The panels comprise locking elements for connecting said panels in both horizontal and vertical direction. In order to consider the often occurring situation that in panelsespecially when stored under changing external conditions, especially changing humiditymight warp, the (vertical) locking element in the panels is constructed with a (slight) play, so that in the event that two panels have slightly different warp nevertheless can easily and reliably be mechanically connected with each other omitting the need to exert an excess of force to fit the panels.

The invention discloses a wooden floor with high utilization, a connection assembly, and a connection structure of a wooden floor with high utilization and a connection assembly. The wooden floor with high utilization includes a floor body. The floor body defines a first groove on one side surface thereof in a horizontal direction. The floor body defines a second groove on the other side surface thereof in the horizontal direction. The first groove and/or the second groove define a notch. The floor body of the present invention is merely required to define grooves on two sides thereof, and is not necessary to provide a protruding male buckle, as long as the first groove or the second groove is connected with a male buckle of the connection assembly, so that wood can be saved, thus increasing a utilization rate of the wood. The wood saved by a single piece of wood floor is limited, but many a little makes a mickle. Moreover, two adjacent floor bodies can be connected by the groove to reserve a certain gap therebetween according to need, which can increase the air permeability of the floor. The use of wood can be greatly saved to protect the ever-decreasing trees, and benefit the human society.

An insulated panel assembly having improved insulative R-value. The insulated panel assembly comprises a cover panel, a first insulation layer, and at least one additional insulation layer, wherein the at least one additional insulation layer has a higher R-value than the first insulation layer. The first insulation layer is secured to the cover panel. The first insulation layer further forms at least one recessed portion. The at least one additional insulation layer is positioned in the at least one recessed portion of the first insulation layer. Examples of the at least one additional insulation layer may include vacuum insulated panels and modified atmosphere insulation panels.

Floor panels include a top portion that is molded from a plastic material. The top portion has a substantially planar top surface and side surfaces. The side surfaces depend downward from the substantially planar top surface forming a cavity in an underside of the substantially planar top surface. A bottom support structure fills the cavity, thereby providing support and shock absorption to the substantially planar top surface.

An apparatus includes a first floor tile that includes a bottom layer that is composed of a wood polymer composite and having a main portion, a tongue portion extending beyond a first edge of the main portion, a groove portion extending within the main portion at a second edge of the main portion opposite the first edge, the base portion having a width. The first floor tile includes a top layer that is composed of ceramic and having a width greater than the width of the main portion, the top layer fixed to the bottom layer such that (1) a first edge of the top layer extends beyond the first edge of the main portion and covers a portion of the tongue portion, (2) a second edge of the top layer extends beyond the second edge of the main portion and covers a portion of the tongue portion.

A floor panel is of synthetic material and forms a layer-shaped substrate with first and second pairs of opposite edges. The first pair of opposite edges has coupling parts forming a first mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking in the plane of the floor panels and perpendicular to the respective edges, and forms a second mechanical locking system, which, in a coupled condition of two of such floor panels, effects a locking transverse to the plane of the panels. The coupling parts on the first pair of opposite edges are realized substantially in the material of the floor panel itself. The floor panel is provided with an edge configuration on the second pair of edges allowing two of such floor panels to be positioned with their respective edge alongside each other and free from mechanical horizontally active locking systems.

Extruded floorboards having integrated standoffs, or legs, to offset them from the ground or floor underneath, are disclosed in which adjacent floorboards share a common leg for standing off. On each side of the cross section of a floorboard, a shorter leg mates with a longer leg of an adjacent floorboard through a tongue & groove. The mated legs are supported by the longer leg and a foot at the bottom of the longer leg. A stiffening rib is included. The longer leg is longer than the shorter leg and stiffening rig by a predetermined distance so as to leave clearance for air bearings or other components underneath an assembled floor.
