• a laminate floor may have been laid floating or glued to the substrate
• the papers are impregnated with aminoplasts and especially with urea resins and / or melamine resins If the papers are pressed with the support plate in a press under the supply of temperature and pressure, so soften the resins and hard from
• the document paper ensures the desired visual impression of the floor formed by the panels By the Schmidtpapier is to ensure that when pressing the layers or papers, the support plate or the panel does not warp
• Parquet panels differ from a laminate in particular by the surface
• the desired optics is by wood and thus not caused by printed paper
• a parquet floor is made of solid wood, but may also have a support plate made of HDF, MDF or chipboard material. However, a wood veneer layer is then applied on the reverse side. In this case, a wood layer or paper is applied in return
• the panels are laid on a floor surface, so occurs when entering the floor, a relatively strong noise development to avoid such a noise development is already provided in the prior art to use a so-called impact sound insulation It is a mounted below a panel layer with sound-absorbing and / or sound-absorbing properties Additionally or alternatively, the layer can cause a shift in the frequencies and the loudness of the generated sound, which are then so that they are subjectively perceived as less disturbing
• the impact sound insulation layer is generally referred to herein as a "sound enhancing layer"
• Sound-enhancing layers are in particular as follows
• the sound-improving layer is regularly elastically deformable in comparison to the panel defined above.
• a layer consists, for example, of polyurethane recycling material, rubber, cork, foams, thermoplastic materials, fiber mats or LDF (low-density material).

• the metal layer is preferably very thin for reasons of cost. The thickness is therefore advantageously less than 1 mm, particularly preferably less than 0.5 mm
• Running on a carpet is comparatively pleasant and quiet the panels have a surface made of textiles, felt or congressfhesen, so the running feeling is comparatively pleasant Also, such panels have a relatively low noise development
• the laying of panels is again comparatively easy compared to laying This is especially true when panels have fasteners that allow glueless joining of two panels. Unlike carpet rugs, soiled areas can be easily replaced when panels are bonded together without glue

• the temperatures are above 200 0 C. They are preferably 230 ° C. to 250 ° C. in order to achieve short pressing times. Short pressing times allow panels to be manufactured quickly, so that the method is inexpensive
• the used sheet or roll goods must be correspondingly temperature-resistant If so pressed at 200 ° C, so the materials used, of which the layers are made, to be selected so that they survive the selected temperature
• Papers or layers adjoining the sound-enhancing layers are preferably impregnated with aminoplast during the production of a laminate panel.
• the aminoplast material used causes the sound-improving layer to be attached to the panel
• connection thus produced between the sound-improving layer and the panel is particularly stable
• the manufacturing process is cost-effective and can be dispensed with the provision of additional adhesives This results in cost advantages Furthermore, the method is environmentally friendly, as no Adhesive must be used, which are also to dispose of solvents, which may be present in adhesives are avoided

• the result is a flush edge termination between the individual layers.
• the panels can also be bigger or smaller After saying more layers can be connected to the announced panels
• polyurethane recycling mate ⁇ al is used and from this the sound-enhancing layer formed
• the material is inexpensive It has very good sound-improving properties It is recovered from the recycling industry, so that it is umweltgeshch If this material is used on the surface, then arise at the same time pleasant running properties as well as new decorative effects
• a sound-enhancing layer should be at least 0.5 mm thick in order to obtain good sound-enhancing properties that are acceptable to the consumer.

• the pressure can then reproduce a wood, a stone or a fantasy image
• a transparent abrasion-resistant layer can be applied
• the sound-enhancing layer thus performs a dual function On the one hand, it forms the carrier for the decor and on the other hand it improves the sense of sound
• the sound-enhancing layer consists in particular of an elastically restrained or thermoplastic material when the sound-improving layer is at the top of a panel. Then impacts are instantly damped when walking and sound waves are only transmitted to lower layers underneath
