A construction panel for installation on a construction surface and interlocking connection to a another construction panel comprises a moisture barrier base to inhibit migration of moisture from the construction surface. The base has a pair of opposed first connector edges comprising a first pair of releasable mating elements, and a pair of opposed second connector edges comprising a second pair of releasable mating elements. A plurality of projections extend from the underside of the base for support and to permit air circulation and drainage of water between the base and the construction surface. In one embodiment, an upper panel having selected physical characteristics is attached to the base. The positioning of the first and second pairs of mating elements on the first and second pairs of connector edges enables the interconnection of entire or partial construction panels.

According to the invention, it is provided that the carrier web (3) comprises as material a copolymer comprising ethylene and vinyl acetate, in particular a copolymer of ethylene and vinyl acetate, preferably ethylene-vinyl acetate (EVA), and/or consists thereof.

A load distributing and absorbing system that lies below a superstructure material which is exposed to percussive forces. The load distributing and absorbing system is interposed between the superstructure material and a foundation. The system has a barrier layer that lies below the superstructure material and an underlayment infrastructure positioned below the barrier layer. Included in the underlayment infrastructure are hat-shaped absorbing members.

A universal membrane is configured to be installed between a subfloor and floor tiles to allow movement of the floor tiles relative to the subfloor. The universal membrane includes a base layer, a plurality of studs projecting from the base layer, and a plurality of sidewalls projecting from the base layer and disposed between adjacent ones of the plurality of studs. Each sidewall of the plurality of sidewalls forming a perimeter of a pocket. The base layer forms a bottom wall of the pocket.

A composite comprising a core, a first cover layer and a second cover layer, wherein the core is provided from an uncut flat body, wherein the core is a three dimensional structure having a first main surface and a second main surface, the first cover layer is in contact with the first main surface creating multiple contact areas and the second cover layer is in contact with the second main surface creating multiple contact areas, wherein the multiple contact areas between the first cover layer and the first main surface are offset in x-direction and y-direction to the multiple contact areas between the second cover layer and the second main surface, characterized in that the first cover layer and the second cover layer are different.

The invention relates to a device for supporting and fastening heating pipes (20) of a heating system placed in subfloors, walls or ceilings of a building. The device comprises: a laminar body having a first face and an opposite second face, a plurality of fastening elements made in one piece on the first face of the laminar body and configured to fasten said heating pipes on the first face. The invention is characterized in that both the laminar body and the fastening elements of the device are in a mixture comprising at least one thermoplastic polymer and thermally conductive inorganic fillers.

The invention relates to a composite tile for an installation system, more particularly for the production of a floor covering or wall covering, comprising a tile of a floor covering or wall covering and a backing disposed on the lay-on face of the tile. The invention also relates to a connecting element for the connection of two composite tiles and to an installation system composed of composite tiles and also to a method for the fabrication of a composite tile. The backing consists of a fiber composite material, more particularly fiber cement.

A structural element, including a base portion and a connecting central pin, has its base portion formed hallow, and having an internal reinforcement in the shape of WOW or MOM, to connect these elements with an insertable central pin so that the cross-section of the pin corresponds to the shape of the chamber between the reinforcements, when the upper surface of the structural element has longitudinal grooves, and is made from a modified polymer or elastomeric material comprising India rubber mixtures. The foundation is monomer ethylene propylene diene or natural rubber or styrene-butadiene rubber and/or combinations of the natural rubber/styrene-butadiene rubber, or thermoplastic elastomers, whose base is monomer ethylene-propylene-diene or polypropylene/monomer ethylene-propylene-diene or polyvinylchloride, or thermoplastic vulcanizates, whose base is monomer ethylene-propylene-diene and polyethylene or natural and/or synthetic rubber, modified by polyethylene or polypropylene.

The membrane is for use with a planar surface and includes a generally planar member and a plurality of resilient tabs. The generally planar member, in use, is disposed in parallel relation to and adjacent the planar surface and, at least in use, defines a plurality of troughs, the troughs being interconnected to define a planar network of troughs that is disposed parallel to the surface, each trough presenting away from the surface in use and terminating in a common plane that is parallel to and spaced from the surface. The tabs are provided for each of one or more of the troughs, the tab lying in the common plane and spanning at least in part across said each trough.

An underlay cushioning sheet that is arranged on the surface of a foundation and that has a waterproof coating film formed thereon. The underlay cushioning sheet includes a cushioning layer having an overlay surface and a curing acceleration layer having a coating film formation surface on the opposite side from the overlay surface. A waterproof coating film including a polyurethane resin is formed on the coating film formation surface of the curing acceleration layer by applying a one pack-type liquid waterproofing material. The curing acceleration layer includes a reactive material capable of reacting with the liquid waterproofing material. The reactive material either (1) includes a functional group capable of reacting with an isocyanate included in the liquid waterproofing material or (2) reacts with a latent curing agent included in the liquid waterproofing material and generates a functional group capable of reacting with the components of the liquid waterproofing material.
