The invention relates to a sheet (10) for protecting a form-work surface, intended to surround a construction material. According to the invention, the sheet (10) comprises at least: a front layer, including at least one polymer material and provided to be in contact with the construction material so as to reduce wear and the formation of grooves on the framework surface and to limit adhesion of the construction material during removal of the formwork; and a rear adhesive layer, provided to be positioned against the formwork surface and rigidly connect the sheet (10) to the formwork surface before the construction material is introduced. The invention also relates to a formwork installation (1) equipped with at least one such sheet (10). The invention further relates to a method of producing and a method of using a sheet (10) of this type.

The disclosure relates to a multilayer panel for producing a floor covering, comprising a wear layer bonded to a back layer, said back layer being made up of at least a thermoplastic material, a plasticizer and fillers, the wear layer comprising a surface layer made up at least of PVC, said surface layer having a Shore D hardness greater than or equal to 60 and a Young's modulus greater than or equal to 1000 MPa.

A film with a gas barrier resin having a glass transition temperature of 70° C. or below and an elastomer, and having an oxygen permeability coefficient of 200 mL/(m.sup.2.Math.day.Math.atm) or less. In a case where tension is applied to stretch the film in a machine direction (MD) at 20° C. such that a twofold increase in length of the film is kept for 30 seconds, and then the tension is released, a ratio L.sub.2/L.sub.1 is 1.5 or less, where L.sub.1 denotes the length of the film prior to application of the tension and L.sub.2 denotes the length of the film subsequent to release of the tension. An elongation ratio at break E.sub.TD/E.sub.MD of the film is preferably 0.9 or more and 1.7 or less, there E.sub.MD denotes the elongation at break in MD and E.sub.TD denotes the elongation at break in the transverse direction (TD).
