    Title: Hydro-insulating, roof boarding or wall membrane
    FIELD OF THE INVENTION
    The invention relates to a hydro-insulating roof boarding or wall membrane, in particular for roof constructions with sloping roofs and for wall constructions. The constructions supplied are equipped with hydro-insulating, roof-boarding or wall membranes and materials that serve as protection against penetrating water and also for the drainage of water from the roof and wall construction. These membranes make it possible, partly due to their construction, to achieve high mechanical parameters, in particular the tensile strength and the nail strength. The strength of the nail is the tear resistance of the membrane at the point of attachment with the nail. This is defined as a maximum force that is required for tearing the nail out of the material, in this case from the membrane.
    State of the art
    The roof construction of the sloping roof usually consists of the roof covering that is mounted on slats and cross bars. A suitable roof covering must be selected depending on the slope of the roof. The hydro-insulating roof boarding membrane or any other insulation is placed under the roof covering, which prevents water penetration into the roof construction or the covered object, for example when snow is blown under the roof covering or if the roof covering is damaged. The roof boarding membranes are watertight, but at the same time permeable to vapor, which makes it possible to evaporate water from the roof construction into the environment. The following membranes are used as fundamental hydro-insulating membranes.
    - polyolefin roof boarding membranes with microperforations, - polyolefin roof boarding membranes with a microporous film, - roof boarding membranes made of special polymers, - bitumen membranes and composites, - composites consisting of, for example, the insulating materials connected to the hydro-insulating layer and other layers.
    The roof boarding membranes are attached to the bottom layer by means of nails, clamps or other fasteners, which can be a formwork or another wooden construction, or the roof boarding membranes are built into entire roof parts.
    Roof board membranes are known on the market on the basis of water systems, namely those that are produced with the technology of subtraction. Subtraction is the designation for the functional layer of the relevant composite material, whereby this designation is derived from the applied technology. These membranes available on the market, however, are only simple two-layer materials, namely a base substrate, usually a non-woven textile, and an upper subtraction layer, this in contrast to complicated systems, which still contain, for example, vapor-permeable films or the like. However, there are no membranes from a composite material with an inner reinforcement layer to achieve such high mechanical properties, such as tensile strength and nail strength.
    Although the solutions mentioned are sufficient for the requirements of the hydro-insulating, roof-boarded or wall-mounted membranes, they have the following disadvantages: - with the current strippers, such high mechanical parameters cannot be achieved and there is no lattice-reinforced membrane or other membrane material on the market that could provide the high mechanical parameters.
    - Insofar as some membranes with a grid or a fabric or other membranes reinforced with a layer are on the market, the functional layer is formed on an acrylate basis and not by a subtraction system, and thus the properties that this layer performs are not achieved, for example a high resistance to UV rays.
    Essence of the invention
    An object of the invention is to eliminate the disadvantages cited and to form a new construction of the roof boarding or wall membranes. The stated object is achieved by a hydro-insulating roof boarding or wall membrane for a roof or wall construction, in particular for pitched roofs, which are accommodated in the roof construction or wall construction, and serves as protection against penetrating water in the roof construction or in the wall construction or in the covered object and also for the removal of any penetrating water and water from condensed vapor from the roof cladding or from the wall, the invention being characterized in that it comprises at least one functional hydro-insulating layer which is vapor-permeable and which has watertightness and which guarantees the vapor permeability of the product, or which contains at least one functional hydro-insulating layer, which is vapor-permeable and which guarantees the vapor-permeable permeability of the product, or at least one functional hydro-insulating layer, which is non-vapor-permeable and which has water resistance and which is non-permeable. vapor permeability of the product, which furthermore guarantees a non-woven cover 1, further comprising a support substrate, further comprising a reinforcing lattice or reinforcing fabric or a non-woven textile, the actual layers being mutually connected.
    According to a further advantageous embodiment, the membrane comprises a functional hydro-insulating acrylate layer, based on aqueous dispersion systems, wherein the support substrate is a fabric or non-woven textile or a similar fabric.
    The functional hydro-insulating acrylate layer is vapor-permeable for the roof boarding membranes and wall membranes or non-vapor-permeable for the vapor blockage or vapor-permeable for the vapor inhibitors, the concepts given being explained in more detail.
    According to a further advantageous embodiment, the actual layers are arranged from top to bottom in this order: above, the functional hydro-insulating layer is accommodated, below is the support substrate, below is the reinforcing lattice or reinforcement fabric or non-woven textile and below is non-woven woven cover textile accommodated, the actual layers being mutually connected.
    According to a further advantageous embodiment, the actual layers are arranged from top to bottom in this order: above is the non-woven cover textile, below is the reinforcing lattice and the reinforcing fabric or the non-woven textile, below is the functional hydro-insulating layer, and below the support substrate is accommodated, the actual layers being mutually connected.
    According to a further advantageous embodiment, the actual layers are arranged from top to bottom in this order: at the top the support substrate is accommodated, below is the functional hydro-insulating layer, below is the reinforcing lattice or reinforcement fabric or the non-woven textile and below is the non-woven woven cover textile accommodated, the actual layers being mutually connected.
    According to a further advantageous embodiment, the actual layers are mutually connected by means of gluing or calendering or extrusion lamination or ultrasonic welding or by means of a combination of these processes.
    The invention consists of a combination of the functional layer of the product from the point of view of watertightness and vapor permeability - it is, for example, an acrylate fabric applied to the non-woven fabric. This function application can consist of several layers. Furthermore, the functional product may consist of a layer which guarantees high mechanical properties, which may be, for example, a reinforcement grid based on polyester, polyamide or polyolefin. The lattice can be protected on the underside by means of a further non-woven textile. The layers are mutually bonded after the laminating process by applying the adhesive, or a laminating, calendering or ultrasonic welding process can be used.
    The entire layered structure can be used for both an application in the wall and in the roof construction.
    The new construction of the hydro-insulating, roof-boarded or wall-mounted membrane has the following advantages: - The function / acrylate application has a high stability from the point of view of UV and heat effect, whereby the reinforcement system is fixed by means of a grid or another very solid non-woven textile guarantees high mechanical parameters, usually defined in a strength greater than 300 Newtons per 5 centimeters in both directions and furthermore 225 Newtons in nail strength, tested in accordance with EN 13859 (part 1-roofing membranes or 2 - windblocks - membranes in walls after application) EN 13984 - vapor blocks and according to further subsequent standards. As long as the mechanical parameters have been measured according to other standards, the equivalent or aforementioned values apply; - When using the polyester lattice, a product is formed that does not contain polyolefin; - The high mechanical parameter increases the safety of the workers on the construction sites, so that in the event that the worker falls down, he can grab at the roof boarding membrane; - The high mechanical parameters guarantee the application even in very demanding conditions from the weather point of view (high load due to snow, areas with a high wind speed, etc.).
    The product can be supplemented with other layers according to the requirements of the application.
    Furthermore, the terms such as vapor-permeable, vapor-permeable, non-vapor-permeable, etc. are specified.
    Vapor permeable is a material that allows water vapor to pass through. All materials are vapor-permeable, it only depends on the amount of water vapor. Vapor permeable is defined by the value Sd - equivalent diffusion thickness. Such a material is considered good vapor permeable in construction, as long as Sd is equal to or smaller than 0.3 m. No material is absolutely non-permeable. Usually a material with the value Sd higher than 20 m is considered non-vapor-permeable. Vapor-permeable is a material with an Sd value of 0.3 - 20 m. The vapor brake is a material with an Sd value of 3 - 20 m.
    The vapor block is a material with an Sd value higher than 20 m.
