The plank may further include optionally one or more of a padding layer and veneer layer below the waterproof substrate. The edges of the planks are routed to form a click locking system, squared or angled edges, or a tongue and groove configuration for assembling different planks together to form a floor or a wall covering. The waterproof substrate includes, in weight percentage, about 20-50% polymer material such as vinyl containing thermoplastics resin, about 20-50% calcium carbonate filler, and about 3-20% of the wood flour. A method is provided to make the floor and wall covering plank. The method includes extruding the waterproof core substrate.

The instant system is a panel made of several layers that is a highly decorative, fire resistant, water resistant, sound proof, R valued insulated, light weight, and energy efficient panel. Such layers include: glass fiber reinforced concrete, glass fiber reinforced concrete with alkaline resistant fibers, alkaline resistant hurricane tested scrim mesh, a solar powered radiant tubing, a fire resistant foam that contains a steel reinforcement, and an epoxy adhesive.

A pre-fabricated construction panel (100) for use on an external surface and/or as part of a building or construction is provided. The panel comprises at least a first layer (110) which is at least partially provided from thermally insulating material having a first surface, said panel comprising at least a second layer (120), said at least second layer being provided from fiber cement board, said second layer having a second surface facing said first surface, said first and second layers being connected one to the other by a spacing means located between and adhering to said first and said second surface, which spacing means provides at least one interspace (140) between the first and second surface, said at least one interspace having at least two openings to the external of said panel for enabling air to flow into and out of the interspace towards the external of said panel. The thermally insulating material means material has a thermal conductivity (lambda) less than or equal to 0.05 W/mK.

The invention relates to a ventilated wall for buildings comprising a thin coating or first layer (1) comprised of porcelain or ceramic stoneware, of marble, of travertine or of volcanic stone or of cement compounds, suitable for being provided at a distance from said building to realize an interspace for air circulation, said ventilated wall comprising a reinforcement system (10) for said first layer (1) comprising, on the side faced toward said building, a second fiberglass layer (2), coupled with said first layer (1), a third layer (3) comprised of foamed material, and a fourth layer (4), the coupling of said layers (1, 2, 3, 4) being realized by gluing material having flexibility properties.

A ceiling tile comprises a first layer of material and a second layer of a structurally stiff material distinct from the material of the first layer, positioned to be below the first layer when installed in a ceiling, wherein the second layer can support its weight and the weight of other layers. The first layer is visible through the openings in the second layer when installed. The second layer might be steel, aluminum, copper, bronze, brass, or iron with openings cut into the second layer. The first layer can be acoustical fiber, wool, fabric, wood, leather, rubber, and acrylic and supported the second layer, with the openings being sufficiently arranged so that the first layer is fully supported by portions of the second layer that are not the openings. Three or more layers are also possible, with some or all of the layers are visible through lower layers.

A method of assembling wall panels includes mounting a plurality of PVC fastening extrusions to a wall in a predetermined parallel, spaced apart relationship, each having a length much greater than a length of a wall panel and having two spaced apart resilient bent end securing walls extending from a base, each securing wall having a projection, each wall panel having a main wall panel and four bent end sections with recesses and corner openings, pressing a bent end section into the spacing between the securing walls to cause deformation and snapping back thereof a projection engages in a respective recess, sliding said wall panel along the parallel, spaced apart fastening extrusions to a desired position with the corner openings permitting said sliding action, and repeating the steps of pressing and sliding for additional wall panels.

Structural insulated wall and roof sheathing systems for use in building construction designed to provide a structural building envelope that is moisture permeable but protects from bulk water, excess air, and thermal transfer.

A set (1) of tiles (5) adapted to cover a surface (10) perpendicular to a thickness direction (V) of the tiles (5), each of the tiles comprising at least one upper layer (24), and an underlying rigid core layer (22), the core layer and the upper layer being superimposed in the thickness direction, and the core layer defining a lower surface (S) opposite the upper layer. The tiles comprise at least one first tile (15) having a first edge extending in a longitudinal direction (L), the core layer of the first tile (15) defining a connecting groove (28) in the first edge. The tiles comprise at least one second tile (20) having a second edge extending in the longitudinal direction, the core layer of the second tile defining a connecting tongue (34) protruding from the second edge, the connecting tongue being adapted to be snap-fit into the connecting groove in a connecting direction (C) perpendicular to the longitudinal direction (L) and to the thickness direction in a locked configuration of the first tile and the second tile. The lower surface defines an additional groove (30) parallel to the first edge.
