The The invention relates to a floor thermal insulating material and a floor thermal insulation layering for application on a raw floor.

Today, there are heat protection regulations for buildings in many countries, which can only be met with targeted thermal insulation. Such a heat protection regulation is in the countries of the European Union the EN 1264 , for Germany also applies the stricter German Energy Saving Regulation EnEV.

thermal insulation For example, on the outside facade of a building, between buildings or individual rooms of a Building and floors of a building be attached. In the thermal insulation of floors It is beside the effective guarantee of the prescribed thermal insulation also important that the thermal insulation, if necessary still footfall sound insulation, screed and flooring, such as linoleum, Parquet, tiles etc., existing floor construction on the Total gross floor is not too high, hence the effective available room height not only due the amount of required thermal insulation is unnecessarily reduced. This is especially true at the retrofitting of insulation on Floors in existing buildings to consider, because there the distance between raw floor and Doors and thus the finished floor already is fixed.

moreover It is important today due to the cost pressure in the construction industry, a easy to install thermal insulation for floors to provide the installation costs of thermal insulation as small as possible.

It is therefore an object of the invention, a Bodenwärmedämmmaterial and a floor thermal insulation layering for application on a raw floor available in which both the applicable heat protection regulations can be met as well as the requirements of a low construction height and easier and less expensive Assembly are fulfilled.

These Task is on the one hand by the Bodenwärmedämmmaterial for protection claim 1 and on the other by the Fußbodenwärmedämmschichtung for application to a bare floor for protection claim 7 solved.

The Floor thermal insulating material has a plate and a tear-resistant and waterproof film. The plate exists expanded polystyrene with granules. The foil is on her Laminated bottom side of the plate and has on its upper side of a film Mark on, the mounting locations for on the plate indicates attachable elements.

advantageous Embodiments of the floor thermal insulating material are set forth in the subclaims.

Preferably the plate is a folding plate. Here, the folding plate is made a plate whose top surface is laminated to the underside of the film is and whose plate underside substantially perpendicular to the underside of the plate at least partially incised, with the underside of the plate in an extension direction in the entire length of the extension direction is cut.

The Foil may be a composite foil which is a polyolefin fabric having a coating of polyolefin.

It is possible on the Bodenwärmedämmmaterial a fastener for attaching attachable to the plate To install elements, wherein the Befestigungsele element through the film is attached to the plate and from the top of the film projects.

The Fastener may have a substantially U-shape. Here, the two legs of the U-shape at their Ends be provided with hook-shaped parts, which for Serve hooking in the plate.

moreover can the fastener on the outsides of his U-shape each one of the U-shape obliquely outward and above projecting support member for supporting of the fastener on the top of the film.

It is also advantageous if the fastening element between the legs of its U-shape has a molded part, the shape of which to the on the plate ( 31 ) is adapted to be fastened element.

The Floor thermal insulation layer for application on a raw floor can be a floor thermal insulating material as previously described and screed have. The floor thermal insulating material is applied here on the unfinished floor and screed is on the floor thermal insulating material applied.

Each of the in 1 shown fasteners 50 has a substantially U-shape and has at the ends of its two legs of the U-shape hook-shaped parts 51 with which the fastener 50 in the floor insulation material 30 can be hooked. Moreover, in 1 a support element 52 shown, which for supporting the fastener 50 serves at the top of the film when the fastener 50 on the floor insulation material 30 is attached. For this purpose, each support element 52 on an outer side of a leg of the U-shape of a fastener 50 is mounted such that it protrudes from the U-shape obliquely outwards and upwards or in the direction of the ends of the leg of the U-shape or protrudes or protrudes. In addition, the fastener has 50 a molding 53 between the legs of the U-shape of the fastener 50 is appropriate. As in 1 shown, lies the molding 53 in the assembled state of the fastener 50 on the floor insulation material 30 flush with a floor heating pipe 40 on, which by means of the fastener 50 on the floor insulation material 30 is mounted. That is, the shape of the molding 53 is at the floor heating pipe 40 or adapted to be fastened element.

2 also shows that on the raw floor 10 applied additional insulation material 20 between which an installation tube 80 for example wise heating, plumbing or electrical installation is inserted, such as a water pipe or floor heating pipes for electrical cables or cables. About the additional insulation material 20 and the installation pipe 80 is again the floor thermal insulation material 30 applied.

The additional insulation material 20 can either mainly have the function of a footfall sound insulation, which thus also simultaneously mitübernimmt a certain thermal insulation function. If a footfall sound insulation is not required, the additional insulation material 20 take over only the function of an additional thermal insulation. However, the additional insulation material can also be omitted. This is especially possible when on the unfinished floor 10 under the floor thermal insulating material 30 no conduit 80 is relocated.

Now the floor thermal insulation material will be 30 with reference to 3 to 5 described in more detail.

As in 3 shown has the floor thermal insulating material 30 a plate 31 and a foil attached thereto 32 which will be described later in more detail. On the slide 32 can be an adhesive strip on the edges 33 , in particular a self-adhesive strip, be attached. In this case, the film overlaps 32 the edge of the plate 31 partly at least in the area of the adhesive strip, as in 3 shown. The overlapping part of the edge of the film 32 with adhesive tape 33 can on a slide 32 another floor thermal insulation material 30 , which is also the edge of the plate 31 at least partially overlapped, are attached to two juxtaposed elements of a Bodenwärmedämmmaterials 30 by means of the film overlap with adhesive strips 33 to connect with each other.

The foil 32 in 3 has a foil top and a foil bottom. The bottom of the film lies in 3 on the plate 31 or on the top of the plate and is not visible. On the upper side of the film are markings in the form of lines 34 and + -signs or crosses 35 intended. The lines 34 and crosses 35 are in the form of a regular pattern or raster on the foil 32 imprinted or recorded. The lines 34 and crosses 35 mark possible attachment locations to which the underfloor heating pipes 40 or elements to be fastened by means of the fastening elements 50 on the floor thermal insulating material 30 and in particular the plate 31 of floor thermal insulating material 30 can be attached to a professional installation of underfloor heating pipes 40 to ensure. An installer can thus easily the required fastening supply locations according to the prescribed installation intervals between the underfloor heating pipes 40 Find. In addition, the orientation of the underfloor heating pipes 40 on the floor or floor thermal insulation material 30 through the lines 34 and crosses 35 and simplifies the screening formed thereby.

The foil 32 is with the foil bottom on the plate 31 Laminated, wherein laminating is to be understood as the joining of several layers of identical or different materials (usually foils) with the aid of suitable laminating agents (lacquer, glue, wax). Laminated in this case, to on the plate 31 a protective layer with markings for possible attachment locations of the fasteners 50 apply and thus an addition of both the material properties of the plate 31 , in particular good thermal insulation and solid polystyrene foam, and the film 32 , in particular tear resistance and water resistance.

• a) Nasskaschieren, womit ein Verbinden mittels nassem Klebstoff bezeichnet wird
• b) Trockenkaschieren, womit ein Verbinden mittels trockenem Klebstoff bezeichnet wird, und
• c) Thermokaschieren, womit ein Verbinden ohne Klebstoffe, jedoch mit Wärme oder Druck bezeichnet wird.

The foil 32 can, for example, with at least one of the three types of laminating on the plate 31 be upset:

• a) wet lamination, which means bonding by means of wet adhesive
• b) dry laminating, which means bonding by means of dry adhesive, and
• c) thermal laminating, which means bonding without adhesives, but with heat or pressure.

The plate 31 is made of polystyrene foam or expanded polystyrene (PS) with a granulate, in particular a heat granules, as in 4 reproduced in greater detail in an enlarged view. Polystyrene foam or expanded polystyrene (PS) is known in Germany, for example, under the registered trade name Styrofoam. The granules give the polystyrene foam a dark, especially gray, color and is in the plate 31 enriched as needed. In addition, the plate has 31 a comparatively greater strength than a polystyrene foam without granules. The traffic load of the plate 31 is at a thickness of 40 mm or 50 mm at 5 kN / m ² . In addition, plates have 31 with a thickness of 40 mm and 50 mm a Torsional Noise (TSM) value of 20 dB (A). The thickness of the plate 31 is preferably in a range of 30 to 60 mm.

As in 1 shown, the hook-shaped parts can 51 the fasteners 50 , in the 1 are shown as needle-shaped or arrow-shaped ends when introduced to and into the plate 31 clamp in the polystyrene foam. The hook-shaped parts 51 are preferably made of plastic and have a much smaller depth than their in 1 shown width and height.

In 5 is a floor thermal insulating material 30 shown in its entirety. How out 5 Obviously, both have the plate 31 as well as the foil 32 one with respect to their length and width directions very small diameter. The plate 31 Because of its material made of polystyrene foam with said granules a comparatively greater strength than a polystyrene foam without granules. The foil 32 has a much smaller thickness than the plate 31 and is thus usually a flexible and usually variable moldable material, which is also tear-resistant, temperature-resistant and waterproof. As a result, on the floor thermal insulating material 30 , in particular the film 31 , Screed 60 , such as cement screed or floating screed are applied.

For better handling of the floor thermal insulation material 30 , especially when laying on a floor, the plate points 31 , at the upper side of the plate, the underside of the film is laminated, at its underside of the plate in three places in 5 board cuts 36 perpendicular to the surface of the plate 31 on. The plate cuts 36 go so far in the thickness of the plate 31 in that the floor thermal insulating material 30 along the plate cuts 36 can be unfolded as in 5 shown. Thus, the floor thermal insulating material forms 30 a folding plate with three partial plates 31 on which the slide 32 is laminated.

In the floor thermal insulation material described above 30 it is therefore a laying ready insulation after DIN 13163/65 For cement and floating screeds with increased thermal insulation, which meets the requirements of the German Energy Saving Ordinance EnEV and thus also the EN 1264 enough. It is also preferably a folding plate with tear-resistant and waterproof composite film after DIN 18560 and DIN 1264 with printed label grid and self-adhesive foil overlap. The insert is according to 4108-10 (4109-2) EN 1264 (4725) and EnEV possible. The floor thermal insulating material 30 is particularly suitable for requirements under the EnEV in the field of soils against soil, outside air and unevenly heated rooms.

The additional insulation material 20 can a ready-to-lay heat and impact sound insulation after DIN 13163/65 for cement and self-leveling screeds with a tear-resistant and waterproof composite foil after DIN 18560 and DIN 1264 is laminated with printed Verlegeraster and self-adhesive film overlap, similar to the Bodenwärmedämmmaterial 30 , The impact sound reduction index (TSM value) is in a range of, for example, 20-34 dB (A). The insert is according to 4108-10, 4109-2 EN 1264 (4725) and EnEV possible. The traffic load of the additional insulation material 20 is at a thickness of 15 mm to 30 mm at 4 kN / m ² . In addition, the additional insulation material 20 in the same form as before for the floor thermal insulation material 30 relating to 5 described be executed as a folding plate.

The previously described embodiments of the floor thermal insulation material 30 and the floor thermal barrier coating for application to a bare floor 10 can be used individually as well as in all possible combinations.

The foil 32 is preferably a composite film of a fabric consisting of at least one polyolefin, such as polypropylene (PP), and a coating, which may also consist of at least one polyolefin, such as polypropylene (PP). The fabric is used for better and more permanent fixation of the fasteners 50 , in the 1 are shown.

For example, the film may 32 have the following properties: a basis weight of about 92 g / m ² after EN 2286 , a tensile strength along about 700 N / 50 mm after ISO 527-3 , a tear resistance across from about 700 N / 50 mm after ISO 527-3 , an elongation at break of about 18% after ISO 527-3 , an elongation at break of about 17% ISO 527-3 , a temperature resistance of about -40 ° C to + 80 ° C. A slide 32 with such material properties is thus a tear-resistant and waterproof film, which is also temperature-resistant in a wide temperature range and has a comparatively low elongation at break.

In addition, as a means for laminating the film 32 at the plate 31 a pressure-sensitive hotmelt adhesive based on hydrocarbons, styrene-rubber copolymers and resins, a specific gravity of 99 g / cm§ after DIN 51757 has, forms a strong surface-sticky, elastic film, an R + K softening point at about 72 ° C after Duke ASTM E 28-99 , a viscosity of about 8000 mPa.s (150 ° C) according to Brookfield DV II, SP 27, 20 RPM, ASTM D 3236-88 , and a viscosity of about 4000 mPa · s (175 ° C) according to Brookfield DV II, SP 27, 20 RPM, ASTM D 3236-88 Has.

The dimension of the plate 31 and the foil 32 may preferably be a width of about 1030 mm. The lines 33 Both in the longitudinal direction and the transverse direction of the film can form a grid with an edge length of for example 5 or 10 cm. Depending on requirements, however, other edge lengths for the grid are possible. This way you can on the slide 32 by means of the lines 33 Raster be formed in either square or rectangular shape. The crosses 34 can be in the center of Squares or rectangles of the grid may be provided.

Even if the number of plate cuts 36 in 5 is given as three, only one plate section, two or even more than three plate cuts are conceivable. The number of panel cuts 36 depends solely on the desired application of the floor thermal insulation material 30 and the thereby required handling. In addition, the plate cuts 36 , in the 5 in the transverse direction of the plate 31 are shown, also in the longitudinal direction of the plate 31 to be available. It is also a combination of panel cuts 36 in the transverse direction and longitudinal direction of the plate 31 conceivable.

Instead of underfloor heating pipes 40 Other tubes can also be used on the floor insulation 30 with the help of fasteners 50 be attached.
