A floor panel may include a substrate and a top layer located above the substrate. The substrate may include a closed cell foamed synthetic material layer with fillers, and have an average density of more than 300 kilograms per cubic meter. The top layer may include a back layer, a printed synthetic material film above the back layer, and a transparent or translucent synthetic material wear layer above the printed synthetic material film. The back layer may include a vinyl compound with fillers, and have a thickness of at least 45 percent of the thickness of the top layer. The floor panel may include first mechanical coupling parts at the pair of long edges and second mechanical coupling parts at the pair of short edges. The first mechanical coupling parts may allow horizontal and vertical locking of two of such floor panels using a turning movement along the respective long edges.

A floor panel may include a substrate and a top layer. The top layer may include a printed thermoplastic film and a thermoplastic transparent or translucent layer provided on the printed thermoplastic film. The substrate may be a synthetic material board including a filler. The substrate may include coupling means provided at edges of the synthetic material board. The coupling means may enable locking with a similar floor panel and prevent separation in a horizontal direction using locking parts with horizontally active locking surfaces. The horizontally active locking surfaces may be oriented at an angle A of more than 90 degrees with the horizontal direction. A first one of the locking parts may be an upstanding part at a bottom lip of a first one of the edges. The angle A may be between (a) a tangent of the horizontally active locking surfaces, and (b) a direction in a horizontal plane that points away from an open curved surface of the upstanding part.

A floor panel has a rectangular and oblong shape, and includes a substrate and a top layer provided on the substrate and forming a decorative side of the floor panel. The top layer is composed of a print provided on a carrier sheet and a transparent thermoplastic layer situated above the print. The substrate has a thickness from 2 to 10 millimeter and forms at least half of the thickness of the floor panel. The substrate is a polyurethane-based substrate and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.

A composite wall assembly edge joint including a first composite buildup pad having a first tapered section is secured to and extends along a first composite face sheet. A second composite buildup pad having a second tapered section is secured to and extends along a second composite face sheet, wherein the first and second composite buildup pads are positioned between spaced apart first and second composite face sheets. A composite flute core member includes a tapered first portion positioned between and secured to the first tapered section and to the second tapered section. A second portion of the composite flute core member extends in a direction away from the tapered first portion of the composite flute core member and is positioned between, extends along and is secured to the first and second composite face sheets.

An interlocking glue stick is a hot-melt glue stick with non-planar features on each end of the glue stick. The non-planar features allow a second glue stick to be coupled to the end of a first glue stick before the first glue stick has been pulled into the hot-melt glue gun. Interlocking glue sticks allow the operator of a hot-melt glue gun to place two or more glue sticks into a position where they can be pulled through a hot-melt glue gun in advance of the need to reload the hot-melt glue gun. This allows the operator to use both hands for purposes of operating the hot-melt glue gun and holding materials in alignment. At least one embodiment of the interlock glue stick allows the non-planar features at each end of the glue stick to be created with a single cut of a cutting tool.

A floor may include a substrate having a top side and a bottom side. A top layer may be provided on the substrate. The top layer may consist of a printed thermoplastic film and a thermoplastic transparent or translucent layer provided on the printed thermoplastic film. The top layer may be directly adhered to the substrate by heat welding the printed thermoplastic film and the top side of the substrate, in the absence of a glue layer. The substrate may be a synthetic material board including a filler. The substrate at least at two opposite edges may include coupling means provided in the synthetic material board. The thermoplastic transparent or translucent layer may be provided with a structure.
