The present invention has the following features. The present invention relates to a flammable flame-proof material provided with a metal material, comprising a metal material and a non-flame-proof-treated thin film sheet on the top of the metal material, wherein an adhesive agent is between the metal material and the non-flame-proof-treated thin film sheet, and relates to an attachment structure for attaching a metal plate with a flammable thin-film construction interior material.

[Object] To provide a building material having excellent durability.

[Solution] A building material has a convex part formed on a surface thereof, the convex part including a first lateral surface part and a second lateral surface part corresponding to the first lateral surface part. The building material is formed from a mixture containing a hydraulic material, an admixture, and a plant-based reinforcing material, and the plant-based reinforcing material at least in the convex part is distributed in the mixture with the hydraulic material and the admixture attached to the plant-based reinforcing material. A distribution of the plant-based reinforcing material in the first lateral surface part and a distribution of the plant-based reinforcing material in the second lateral surface part are substantially the same. Desirably, the convex part includes a first edge part that is an edge part of the first lateral surface part and a second edge part that is an edge part of the second lateral surface part and that corresponds to the first edge part, and a distribution of holes formed in the first edge part and a distribution of holes formed in the second edge part are substantially the same.

The present disclosure provides an artificial floor. The artificial floor comprises a plate body with a pad portion on a surface thereof. The pad portion contacts with a subfloor when the plate body is disposed on the subfloor. The plate body could be various kinds of the simulated floor such as linen, wood, or stone. The simulated floor is poor in wear resistance. The vibration or shaking during transportation may cause wearing between the simulated floors so as to damage the surfaces of the simulated floors. The subfloor may have an uneven surface, which may affect the surface flatness of the plate body disposed on the subfloor. Therefore, the pad portion of the plate body could be used as a cushion for the transportation process to protect the collision and wearing between the plate bodies. The pad portion could also be deformed locally to close the surface of the subfloor.

The invention relates to a flooring panel suitable for constructing a floor covering, which panel comprises a core layer and a decorative top layer and a layer situated between the core layer and the decorative top layer which enables improves sound performance.

Waterproof engineered floor and wall planks have a veneer layer bonded with a plastic composite core, and an underlayer, preferably an underlayer of cork.

An engineered wood product with at least one engineered-wood substrate or core layer (such as, but not limited to, OSB), with a connectivity layer configured to reflect RF signals (e.g., wifi and/or cellular signals), thereby enhancing connectivity in adjacent or proximate spaces or areas. The connectivity layer may be a metallic material, such as, but not limited to, aluminum or copper. The layer may be a sheet or film or foil of the metallic material applied to the surface(s), or integrated into the interior, of the substrate or core layer. The layer also may be a coating or deposited layer. A connectivity layer may be “sandwiched” between two or more engineered-wood substrates, thereby forming a composite panel or product. The surface of the connectivity layer may be embossed or patterned.

A thermoplastic composite article comprising a porous core layer and an open cell skin disposed on a first surface of the core layer is described. The composite article comprises a noise reduction coefficient of at least 0.5 as tested by ASTM C423-17 and a flame spread index of less than 25 and a smoke development index of less than 150 as tested by ASTM E84 dated 2009.

Provided is a panel, in particular a floor panel, ceiling panel, or wall panel, having a laminated multi-layer structure which includes a core layer, a decorative layer above the core layer, a transparent top layer above the decorative layer, and an intermediate layer situated between the decorative layer and the top layer. The intermediate layer is transparent, and made from a protective material which includes a polyurethane composition which is the reaction product of a polyester polyol, a polyether polyol, and an isocyanate. The polyurethane composition is a thermoset polymer material. Also provided is a use of an additional layer in a laminated multi-layer structure of a panel in particular a floor panel, ceiling panel, or wall panel. The additional layer is transparent, and is made from a protective material which includes a polyurethane composition which is the reaction product of a polyester polyol, a polyether polyol, and an isocyanate. The polyurethane composition is a thermoset polymer material.

The invention relates to a flooring panel suitable for constructing a floor covering, which panel comprises a core layer and a decorative top layer and a layer situated between the core layer and the decorative top layer which enables improves sound performance.

A tile system for covering a surface. The tile system comprises a first tile assembly connected to a second tile assembly by a connector. Each tile assembly comprises a first tile stacked on a second tile, the first tile and the second tile joined to a reinforcing material disposed therebetween. The connector comprises a first component and a second component that is complementary to the first component. The first component is mounted to the first tile assembly, and the second component is mounted to the second tile assembly.
