Definitions

  • the invention relates to an insulation element for thermal and / or acoustic insulation a building roof construction, in particular a rafters and purlin roof a residential building that can be installed between neighboring rafters.
  • Insulating elements for heat and / or sound insulation are in itself by the load-bearing parts and through outside covers / seals respectively the room-side cladding of the roof structures resulting spaces built-in.
  • the load-bearing parts mostly consist of solid wood, glued wood, Bridge beams, boards, etc.
  • Another application of such insulation elements exists in the area of floor ceilings as a boundary surface to the surroundings, as far as these floor ceilings at least with supporting wood clad on the underside are provided, between which insulation elements can be arranged.
  • the insulation elements to be preferred are made of mineral wool fibers made of insulating felts glued onto carrier foils in graded widths between 50 and 100 cm, so that an insulating felt is selected according to the rafter width and can be processed.
  • the graded widths lead both from the Manufacturer as well as on the part of the stocking dealer or the processing Companies to a large stock of individual products.
  • the construction area to be insulated, especially with regard to the rafter width carefully measured before the insulation felts of the appropriate width are selected, whereby in usually the gradation is in the 10 cm range, so that additional cutting work insulation felts are required.
  • the width of the insulation felt is greater than the rafter width large, it is necessary to cut the insulation felt through a longitudinal cut to the rafter width adapt.
  • the insulation felt may be adjusted over several meters, which is cumbersome in the mostly narrow loft spaces. It there is also a risk that the generally in the rolled state supplied insulation felt can only be processed imprecisely, so that only one insufficient heat and / or sound insulation is achieved. Insulation felts therefore mostly pressed into the rafters with excess width, which leads to building physics Problems due to lack of back ventilation can, at least always results in increased consumption of insulation materials.
  • the poor Laying - also with sub-widths - is covered by the carrier foils on the underside and is usually not recognizable to the building owner.
  • Another solution is to use insulation felts with a higher bending stiffness to use that rolled up under pressure in the manufacturing plant to save space be and of which after unrolling sections according to the width of the Rafter fields are separated. Applied to one of the large surfaces striped markings make it easier to cut to length. But it is considered a disadvantage considered that with increasing insulation thicknesses, for example ⁇ 140 mm different tensile and compressive stresses in the zones of the insulation roll become too large so that they tear on the outside or on the inside structural damage from over-compression. Reduce both damages the stiffness of the insulating felt section, so that there is a not inconsiderable risk, that the insulation element under the force of gravity from the rafter field falls out before a load-bearing sub-layer is installed.
  • Rollable and compressible insulation felts usually have a pronounced laminar arrangement of the individual fibers.
  • One results from this orientation high compressibility perpendicular to the large areas and on the other hand one extremely low transverse tensile strength and shear strength.
  • When rolling up Such insulation materials are shifted against each other. After unrolling, the individual layers gap apart, which naturally increases a reduction in strength and difficulties when installing these insulation felts can lead.
  • the length of the rolled-up insulation felt or the roll diameter drastically increase. In any case, there are disadvantages with regard to Processing the insulation felts.
  • the invention has for its object to further develop a generic insulation element such that its installation between rafters is significantly simplified and rationalized without the disadvantages described above, in particular a deterioration in thermal and acoustic insulation is caused.
  • the insulating element consists of a plate made of mineral wool fibers, the mineral wool fibers being aligned at least ⁇ 90 degrees to the adjacent side surfaces of the rafters in the area of the side surfaces of the plate adjacent to the rafters, and wherein the plate is a Has a length of at least 2 m with a material thickness of ⁇ 100 mm and usual width.
  • the insulation element according to the invention for thermal and / or acoustic insulation Building roof construction thus shows sufficient stability to to be placed between the rafters without the risk of falling out consists.
  • the fiber arrangement also enables an extraordinary good interlocking of the insulation material with the rafters surface, because of the fiber arrangement on the one hand the necessary rigidity for the required friction pressure provides and on the other hand sufficient compressibility of the Insulation board in its longitudinal direction allows.
  • Insulating element advantageous that a large-sized plate is formed can be cut according to the rafter spacing without that sections can no longer be used.
  • the design of the Insulation element as a large-format plate thus enables a far-reaching Adaptation of the insulation element to the rafter spacing and beyond that economical and fast processing of the insulation elements.
  • the angle between the adjacent side surfaces of the rafters and the grain between 0 and 45 degrees. It is advantageous here that the positive engagement of the The flatter the fibers, the tighter the insulation material with the rafters surface are. On the other hand, the stiffness decreases parallel to the big ones Surfaces so that the clamping effect of the insulation elements drops.
  • the optimal one Angle of attack is dependent on the width of the rafter field, however also significantly from the desired resistance moment of the insulation material, which is significantly influenced by the thickness of the insulation material.
  • the arrangement of the Individual fibers are therefore dependent on a further feature of the invention varies from the thickness of the insulation.
  • the plate preferably has a material thickness of more than 120 mm also to meet the higher requirements for insulation performance.
  • the plate Glass and / or rock wool fibers and / or their derivatives are provided.
  • the mineral wool fibers are preferably over the entire extent of the Plate at an angle ⁇ 90 degrees, preferably ⁇ 45 degrees to the adjacent Side surfaces of the rafters aligned, so that the advantageous orientation of the Mineral wool fibers are also present in the areas after cutting to length the plate are outer surfaces which abut the rafters.
  • the individual fibers are completely oblique to the in the direction of the longitudinal axis large surfaces.
  • a surcharge of, for example, 1.2 cm from the Insulation board separated, which sections are pressed between the rafters.
  • the usual installation technique is that the section first to a the rafters flanks are attached and then pushed into the rafters field.
  • the inventive arrangement of the individual fibers allows the insulation element be compressed more with the same effort, so that it is easier in the rafter field can be pushed in.
  • the individual fibers in the edge area are due to the possible large compression of the insulation element when installed in redirected and displaced only slightly in a deeper area, whereby there are advantages in the insulation effect of the insulation elements.
  • the plate in at least one large Surface has incisions that are perpendicular to the length of the tarpaulin run.
  • the incisions are evenly spaced from one another, for example, individual cuts compared to other cuts through greater or smaller depth and / or width as well as color markings or the like are highlighted.
  • the one in the big surfaces Incisions made at the factory can have depths of at least 5 mm have several centimeters.
  • the section of the incised The plate is clamped between the rafters so that the cuts on the top, i.e. installed in the pressure zone of the horizontal or parallel to the roof pitch Insulation element.
  • the incisions can be made at regular intervals, for example be provided every 2 cm.
  • the regularly required width of the insulation from 1 to 5 cm, preferably taken into account 1 to 2 cm. If, for example, regionally determined Rafter widths are preferred, they can be alone or excellent be marked.
  • a surface the plate is partially or completely provided with a color coating to a To ensure orientation for the installation of the plate.
  • the insulation panel on one side with, for example, glass fleece, tissue, paper or similar. to cover non-positively.

  • the insulation element next to the insulation board Has insulation board and / or insulation felt section, which is arranged laterally on the board , the width of which corresponds to the thickness of the plate.
  • the insulation board and / or insulation felt section is glued to a glass fleece.
  • a mineral wool product is used for this, which is a lower one Compressive strength, as the mineral wool product for the insulation board.
  • the insulation material for the insulation board and / or insulation felt section a compressive strength that is parallel between that of the insulation board to the large areas and a slightly compressible insulation felt.
  • the sections are used as filler pieces, so that after processing a Plate narrow sections must be separated from the next plate.
  • the fibers preferably run in the insulation board and / or insulation felt section essentially parallel to the adjacent side surfaces of the rafters.
  • Figure 1 is an insulation element 1 for thermal and / or acoustic insulation Building roof construction, in particular a rafter and purlin roof Residential building shown.
