A trestle mat construction panel configured for use with building equipment and a method of manufacture and use thereof. The trestle mat construction panel is preferably formed of a partially hollow core body and strong support material to allow the construction panel to be easily placed and moved and to support various materials, such as construction equipment including cranes and the like, when in use.

Separating membrane of plastic material, made up of a bossed and waterproof sheet which is coupled with a permeable base layer. The bosses are of the cylindrical type with a double diameter and have such a shape and arrangement as to feature improved adhesion on both faces. The gripping of the adhesive is increased in order to obtain greater tear strength, on the upper face, and at the same time increases the area of contact with the base layer for a greater resistance to delamination on the lower face. In particular, inside each chamber there is an internal crown, which divides it like a necking into two superimposed compartments having the same diameter, wherein the first compartment has a depth amounting to at least of the total. A production process for obtaining the membrane is also disclosed.

Gypsum board having a core, said core having at least one side covered with a non-woven fabric; characterized in that the inner side of the non-woven fabric, which is in contact with the core of the gypsum board, has a surface roughness Ra of from 25 to 60 micrometers, preferably from 25 to 50 micrometers, advantageously from 25 to 40 micrometers.

An exterior sheathing cementitious panel which prevents water penetration and air leakage is provided. Methods for manufacturing exterior sheathing cementitious panels with a highly efficient integrated air/water barrier sheet are also provided. An exterior sheathing system employing the exterior sheathing cementitious panel is provided.

Gypsum panels, sheathing systems, and methods of making and using the same are provided. A gypsum panel includes a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core, wherein gypsum penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated. A building sheathing system includes at least two gypsum panels and a seaming component to provide a seam at an interface between the gypsum panels.

Separating membrane (10) of plastic material, made up of a bossed and waterproof sheet (100) which is coupled with a permeable base layer (101); the bosses (102) are of the cylindrical type with a double diameter (D1, D2) and have such a shape and arrangement as to feature improved adhesion on both faces (110-111). The invention increases the gripping of the adhesive in order to obtain greater tear strength, on the upper face, and at the same time increases the area of contact with the base layer for a greater resistance to delamination on the lower face. In particular, inside each chamber (103) there is an internal crown (104), which divides it like a necking (D2) into two superimposed compartments (105-6) having the same diameter (D1), wherein the first compartment has a depth (H1) amounting to at least of the total (H). The invention also relates to the production process for obtaining said membrane (10).

The invention relates to a floorboard (1, 2) which has a carrier plate (3) having a top-side veneer (4), in particular a wood veneer. The carrier plate (3) and the veneer (4) are connected to each other via a resin (6). There is an edge strip (14, 15) at least on two side edges (12, 13) of the veneer (4). Said edge strip (14, 15) consists of resin (6). Carrier plate (3) and veneer (4) having the resin (6) are hot-compressed to each other. During compressing, pores, cracks, and/or gaps in the veneer (4) are filled with resin (6).

A floor, wall, or ceiling panel and to a method for producing same. The panel has a base made of a wood material and an upper veneer. The base and the veneer are hot-pressed together while incorporating a resin layer. During the pressing process, pores, cracks, and/or gaps in the veneer are filled with resin. In particular, the pressing process is carried out such that the veneer is saturated with resin, and the resin can be seen on the surface of the veneer after the pressing process. The adhesion of the veneer to the base and the smoothing of the veneer are thus carried out in one operation.
