    The invention relates to an insulation board for insulating a roof, in particular a flat roof, an underside of the insulation board being provided with lower projections with which the underside of the insulation board can be arranged at a distance from an outside of the roof.
    Roofs are one of the most stressed components in building construction. Moisture damage is particularly common in flat roofs, for example due to a porous or otherwise aged roof seal or due to precipitation during the construction phase. Apart from the mold problem, moisture in insulation materials, especially mineral wool insulation materials, reduces the insulation properties and the load-bearing capacity of the roofs, which can significantly impair the functionality of the roofs. In addition, damage to the roof waterproofing or its components as well as the roof structure due to an insulation material that has become too soft and / or a long-lasting excessively high moisture content is to be expected, as well as a noticeable reduction in thermal insulation solely due to the loss of thickness of the damp insulation material.
    In the event of moisture entering or penetrating, a renovation of the roof is usually necessary, as drying out of the dampened insulation layer is often not possible or takes too long and is associated with consequential damage to the substructure or with the formation of mold. To repair such damage from the outside, the existing waterproofing and the soaked insulation are currently being removed from roofs. These layers must then be reapplied.
    From EP 2 186 958 it is known to provide insulation elements with rear ventilation means in order to remove moisture below the insulation. However, the drying potential of this solution is too low to repair major moisture damage.
    DE 360 03 74 shows a device for the early detection and localization of water damage, a pipe being inserted into an insulation layer of a roof / 31, which has sensors that detect the moisture in the transition area between
    Can measure ceiling and insulation. A possibility of renovating a roof or avoiding consequential damage is not shown.
    DE 360 56 33 shows a possibility for dehumidification and for early detection of water damage on a flat roof, a downpipe being led through the concrete ceiling below the insulation. This device is complex and error-prone, especially since the substructure of the roof has to be opened. In itself, such an opening should always be avoided.
    The object of the invention is to provide an insulation board with which the above disadvantages can be avoided and with which an existing roof can be renovated, the insulation material of damp-damaged roofs being able to be left in place and instead of being removed and replaced the insulation allows the wet insulation to dry. In addition, the insulation of a newly manufactured roof is to be made possible, and in the event of water ingress, drying takes place automatically and consequential damage can be avoided.
    This object is achieved by an insulation board with the features of claim 1.
    Since the insulation board has lower projections on its underside, i.e. on the side that is attached to the outside of the roof, it is possible to mount the insulation board on the outside of the roof while leaving a cavity underneath the underside of the insulation board. This cavity is created by arranging the underside of the insulation board at a distance from the outside of the roof, the projections resting on the outside of the roof and the parts of the underside apart from the projections being at a distance from the outside of the roof and thereby forming a cavity. This cavity serves to ventilate the existing roof or the substructure as well as a vapor barrier of a newly insulated roof arranged thereon.
    / 31
    The insulation board according to the invention can be used in two applications. On the one hand, it is conceivable to arrange this insulation board as insulation of a newly erected roof directly on the possibly sealed substructure instead of a conventional insulation board. Alternatively, the insulation board according to the invention can also be used on an existing insulation. In this case, the existing insulation, which may be sealed, forms the outside of the roof, from which the underside of the insulation board according to the invention is arranged at a distance. This is particularly useful in cases where moisture-damaged existing insulation has to be renovated.
    The mere ventilation is not sufficient in the case of water ingress or for the renovation of a roof damaged by moisture in order to dry it out. It is therefore provided according to the invention that the insulation board has a first through hole for the arrangement of a ventilation device. As a result, air can initially flow into the cavity created by the projections from the outside of the roof and the underside of the insulation panel. A second through hole is provided for the arrangement of a ventilation device, by means of which air can flow out of the cavity, which can result in a convective flow. In the case of moisture-damaged existing insulation, the moisture can be removed via the convective flow and the existing insulation can dry off. This is also possible if moisture enters a roof insulated with an insulation board according to the invention as a result of water damage. The moisture generated on the underside of the insulation board is removed convectively by means of the ventilation and ventilation device.
    Further advantageous embodiments of the invention are defined in the dependent claims.
    In one embodiment, the lower projections are designed as a plurality of knobs. The knobs rest on the outer layer of the roof, i. H. on the possibly sealed substructure or on the existing insulation of a roof.
    / 31
    In a preferred embodiment of the insulation board according to the invention, the lower projections form a lower channel-shaped structure at least in regions. In other words: the projections form the wall of channels through which the air flowing in by means of the ventilation device flows to the ventilation device and can escape there from the channel-shaped cavity. This removes moisture convectively. A channel structure has several advantages. On the one hand, the air flow can be directed from inlet openings in the ventilation device to outlet openings in the ventilation device by means of a channel-shaped structure. The air flow is maintained through the duct, so that larger amounts of moisture can be removed convectively and the drying potential is increased. The cavity created between the underside of the insulation panel and the outside of the roof can be smaller in the case of such a lower channel-shaped structure. This results in a larger surface with which the insulation board rests on the outside of the roof, which increases the insulation effect.
    As a rule, roof areas are too large to be covered by an insulation panel designed as a single component, even if this would have advantages in terms of the insulation effect. The insulation board according to the invention can therefore also consist of individual elements which are assembled during assembly on the roof. It is preferably provided that the first through hole for the arrangement of the ventilation device and the second through hole for the arrangement of the ventilation device are arranged on different elements of the insulation board in order to allow a sufficient distance between the ventilation device and the ventilation device. The distance between the ventilation and the ventilation device can be, for example, between 5 m and 30 m, preferably between 10 m and 20 m. No through holes are provided in other elements, only the lower projections arranged on the underside. In the case of a lower channel-shaped structure, it is advantageous if the assembled individual elements form a continuous channel for the air flowing through. In principle, it is also possible that in the first through hole for the arrangement of the ventilation device and the second through hole for the arrangement of the ventilation device in one and the same / 31
    Element of the insulation board are arranged. In the assembled state, an insulation board according to the invention then results in any case.
    The formation, at least in some areas, of a lower channel-shaped structure means that the channel-shaped structure does not have to extend over the entire underside of the insulation board. For example, it may be sufficient if such a channel-shaped structure is provided in the vicinity of the first and second through holes.
    The lower channel-shaped structure can be designed as lower grooves arranged in the insulation board. This enables particularly simple production of a channel-shaped structure. For example, the lower grooves can be designed as a profile of the underside of the insulation board. This profile can be milled into the insulation board or can be created in the course of manufacturing the insulation board.
    The lower grooves can be arranged in the longitudinal direction of the insulation board or perpendicular to the longitudinal direction. However, it is preferably provided that the lower grooves are arranged in the longitudinal direction of the insulation board and perpendicularly thereto, preferably in a regular pattern, the lower grooves being connected to one another. In the case of a regular grid on lower grooves, this results in a regular grid of interconnected ventilation ducts, which means that air can flow through the insulation panel over a large area when installed. This in turn is associated with a particularly high air throughput and a corresponding drying potential.
    In a preferred embodiment of the invention, the top of the insulation board is provided with upper projections. This can also create a cavity in the upper region of the insulation board, in which roof elements, which are arranged on the top of the insulation board, such as a further insulation board or a covering layer with the upper projections can be arranged at a distance from the top of the insulation board. Similar to the case of spacing the underside of the insulation board, a cavity is created between the top of the insulation board and the component to be arranged on it. By air from inlet openings of the / 31
    If the ventilation device flows into this cavity and subsequently flows out of this cavity from the cavity via outlet openings of the ventilation device, moisture can be removed convectively and the drying in the event of water damage in the inventive insulation board or when renovating a moisture-damaged existing insulation can be further improved.
    Again, the upper projections can be designed as a plurality of knobs. It is preferably provided that the upper projections have an upper channel-shaped structure. The projections thus represent the wall of an air duct through which air can be directed from the ventilation device into the ventilation device.
    During the drying of the existing insulation or in the event of water damage in the insulation board according to the invention, not all of the moisture can be removed convectively. As a result, the insulation board itself inevitably absorbs moisture. Due to the arrangement of an upper channel-shaped structure at least in some areas, this moisture can be reduced by convective flow in the same way as the moisture accumulated on the underside, so that the insulation board can dry quickly.
    The upper channel-shaped structure can have the same features as the lower channel-shaped structure, with the same effects. The upper channel-shaped structure can be designed as upper grooves arranged in the insulation board, for example as a profile of the top of the insulation board. Alternatively, it is also possible, in turn, to arrange a further insulation plate with knobs or grooves on a flat top of the insulation plate, whereby the upper channel-shaped structure is designed to be closed.
    The upper grooves can be arranged in the longitudinal direction of the insulation board or perpendicular to the longitudinal direction, but again it is preferably provided that the upper grooves are arranged in the longitudinal direction of the insulation board and perpendicular to the longitudinal direction, preferably in a regular pattern, with the upper grooves in one another Connect.
    / 31
    In one embodiment of the invention it is provided that there are air-permeable cross connections from the bottom of the insulation board to the top of the insulation board. For example, the lower channel-shaped structure is connected to the upper channel-shaped structure, whereby an even greater air throughput can be made possible, which further increases the drying of the existing insulation or the insulation board. The cross connections can be realized, for example, by perforations transverse to the board level of the insulation board. In the case of a regular grid on the upper and lower ventilation ducts, the crossing points of the upper grooves can be connected to those of the lower grooves, for example.
    An insulation board made of foam is preferably provided, a moisture-insensitive raw material, for example polystyrene, being preferred. Molded or automatic foamed polystyrene or extruded polystyrene (XPS) is well suited.
    In one embodiment of the invention, the insulation board has a thickness between 5 mm and 400 mm, preferably between 75 mm and 200 mm. This thickness is measured between the underside of the lower projections and the top of the insulation board or - if necessary - the top of the upper projections.
    In principle, the dimensions of the insulation board can be chosen arbitrarily and to match the respective roof area. To renovate an entire roof, the insulation board can be subdivided, whereby lengths and widths of less than 2 m have proven to be practical. During assembly, the individual elements of the insulation board are then put together to form an overall insulation board, the lower and possibly the upper channel-shaped structure of the respective elements merging into one another, so that a channel-shaped structure is created overall. It can be provided that an insulation panel consisting of many individual elements covers a total roof area of up to 500 m 2 . In other words, an insulation board with a first and a second through hole is required for each 500 m 2 area of the roof for the arrangement of the ventilation and ventilation device. It has proven to be useful that the ventilation device is arranged at the low point and the ventilation device at the high point. If there are several insulation panels / 31, the ventilation and ventilation devices can be arranged in a row.
    The lower projections and / or the upper projections can for example have a height between 5 mm and 50 mm, preferably between 10 mm and 20 mm. The upper grooves and / or the lower grooves can have a width between 5 mm and 50 mm, preferably between 15 mm and 25 mm.
    The invention further relates to an insulation system for roofs, in particular for renovating roofs, comprising an insulation plate as described above, which is arranged on the outside of a roof, a ventilation device which is arranged in the first through hole of the insulation plate and a ventilation device which is in the second through hole is arranged in the insulation board.
    By providing that the ventilation device has a lower opening and the ventilation device has a lower opening, air can flow from the ventilation device into the cavity defined by the lower projections, preferably the lower channel-shaped structure, and from there further into the ventilation device. By means of one or more insulation systems according to the invention arranged on the outside of the roof to be renovated, the existing roof is insulated or a new roof is insulated, the insulation system being flowed through convectively and thereby being able to remove moisture. The driving force for the convective ventilation of the channel-shaped structure is the ventilation and ventilation device, which can be mounted on the top of the roof when the insulation system is installed. In the case of a refurbishment, the ventilation and / or ventilation device can be located entirely outside the existing roof or can rest on the outside thereof. However, it is also possible for the ventilation and / or ventilation device to protrude into the insulation level of the existing roof when the insulation system is in the assembled state.
    In the installed state of the insulation system, the ventilation and ventilation device form suitable supply and exhaust air openings in the roof area, which are connected to one another via the cavity, preferably via the lower channel-shaped structure / 31, so that air can flow through the insulation system as completely as possible and thus moisture over a large area can be removed convectively. Via the ventilation and ventilation device, the moisture can be released to the outside air via the cavity, preferably via the lower channel-shaped structure, and moisture-damaged existing insulation or moisture damage in the insulation board can thus be dried primarily by convection.
    It has been shown that the insulation system according to the invention has a promising drying potential for moisture-damaged roofs. This applies particularly to roof-insulated flat roofs. Both in real tests and in simulations, the existing insulation was completely dried off in a short time.
    By maintaining the old roof structure, the work involved in the renovation is significantly reduced and the insulation effect of the old insulation that recurs after drying is also used. This significantly increases the cost-effectiveness of the renovation measures.
    In the case of insulation of a new roof with an insulation system according to the invention, precautionary measures are taken against newly created moisture damage. If there is water damage, the insulation board is quickly dried off so that consequential damage, such as mold growth, is avoided.
    In a preferred embodiment of the invention, the ventilation and / or the ventilation device have lower openings for the air flowing through, which open directly into the lower channel-shaped structure. In the installed state of the insulation system, the ventilation and / or ventilation device thus form supply and exhaust air openings in the roof area, which are convectively short-circuited with the lower channel-shaped structure and thus enable a particularly high air throughput in the insulation system with a correspondingly high drying potential.
    / 31
    In a particularly preferred embodiment of the insulation system, ventilation channels in the form of an upper channel-shaped structure are also arranged on the upper side of the insulation board, which in turn is connected to the ventilation device and the ventilation device, so that air from the ventilation device into the upper channel-shaped structure and from the upper channel-shaped structure Structure can flow into the ventilation device.
    In a preferred embodiment of the insulation system, the ventilation device is designed as a ventilation pipe and / or the ventilation device as a ventilation pipe. The ventilation and / or the ventilation device thus function as supply and / or exhaust air pipes, with which the cavity on the underside, preferably the lower channel-shaped structure and - optionally - the cavity on the top, preferably the upper channel-shaped structure, are convectively ventilated.
    It can further be provided that the ventilation device and / or the ventilation device has a convection device which maintains the convection. This can be, for example, a wind-driven ventilation fan, whereby the convection is maintained wind-driven and without the use of energy. The ventilation fan can be attached to the ventilation device, for example. The rotation of this fan creates a vacuum that actively draws air through the insulation system. In the case of an arrangement on the ventilation device, air can be actively conveyed into the insulation system.
    In one embodiment, the insulation system has a slope insulation on the top of the insulation board. This makes sense if the existing roof has no slope at all. Furthermore, it can be provided that a seal is provided on the top of the insulation board or on the top of the slope insulation, for example a foil seal or a bitumen membrane.
    The invention further relates to a method for renovating an insulated roof, which comprises an existing insulation and an existing seal arranged on the outside of the existing insulation / 31, which is perforated in the course of the method according to the invention or at least removed in certain areas, as a result of which the moisture can better escape from the existing insulation , It is preferably provided that the existing and possibly defective existing seal is perforated, preferably as uniformly as possible and over the entire area, so that the moisture which has penetrated can be dissipated as widely as possible.
    Subsequently, at least one insulation system as described above is arranged on the existing seal, the ventilation and ventilation device of the insulation system forming suitable supply and exhaust air openings in the roof area, which are connected to one another via the lower channel-shaped structure in such a way that air forms the insulation system can flow through as completely as possible and thus moisture can be removed convectively. As a result, the principle of the insulation system, namely the drying of the existing roof or water damage in the new insulation, primarily by convection, can be implemented.
    After perforation or removal of the existing waterproofing of the existing roof in certain areas, the insulation panel provided with the lower projections, for example in the form of assembled individual elements, as well as with the ventilation device and the ventilation device on the existing seal on the outside of the existing insulation. The ventilation and / or the ventilation device can be installed entirely outside the existing roof or rest on the outside thereof. However, it is also possible for the ventilation and / or ventilation device to protrude into the insulation level of the existing roof when the insulation system is in the assembled state. The ventilation and / or the ventilation device have openings, the ventilation and / or the ventilation device being preferably convectively short-circuited with the existing insulation. This can further support drying. In the case of a lower channel-shaped structure, ventilation channels are formed, so that the ventilation and ventilation device, which is designed, for example, as a supply and exhaust air pipe, releases the moisture from the ventilation channels to the outside air and the existing roof, in particular the existing insulation, is dried.
    / 31
    After the completion of the drying phase, the ventilation and / or ventilation device is removed or closed and, if necessary, insulated. In the case of removal, it makes sense to cover the resulting recesses in the insulation board with insulation material and seal them tightly. The ventilation and / or the ventilation device can be closed, for example, with a suitable insulation cylinder which is pushed into the ventilation and / or the ventilation device. Common insulation material can be used.
    The insulation system can thus remain on the existing roof and represents additional insulation via the insulation panel. Thus, not only can a dampened existing roof be renovated with the insulation system according to the invention, but additional insulation is also provided with which the insulation of the roof is further improved , The parapet is increased by the thickness of the insulation system, i.e. essentially by the thickness of the insulation board.
    In one embodiment of the invention, the existing seal is perforated generously by means of longitudinal cuts. These allow stronger ventilation than perforated perforations on the one hand and are easier to manufacture on the other.
    Further details and advantages of the present invention are explained in more detail below with the aid of the description of the figures and with reference to the drawings. It shows:

    FIG. 1 a shows a plan view of the underside of an element 1 a of an insulation board 1 according to the invention in a rectangular shape, in this exemplary embodiment the length in the longitudinal direction being 125 cm, while the length perpendicular to it is 60 cm. The first through hole 10 for arranging the ventilation device 8 is arranged in the element 1a. 1b shows a further plan view of the underside of the element 1b of the insulation board 1 according to the invention, in which the second through hole 11 is provided for the arrangement of the ventilation device 9. 1c shows a plan view of the underside of a further element 1c of the insulation board 1 according to the invention. The element 1c has no through holes. The insulation board 1 according to the invention can be assembled by assembling the element 1a and the element 1b. For this purpose, the elements 1a, 1b have a border with a stepped rebate 24, which allows a precise fitting, whereby insulation losses can be avoided. However, it is preferably provided to arrange a plurality of elements 1c between the element 1a and the element 1b, which likewise have a border with a step fold 24.
    Apart from the through holes 10, 11, the elements 1a, 1b, 1c are constructed identically. The lower projections 3 are approximately square elevations on the underside 2 of the elements 1a, 1b, 1c, which are arranged in a regular pattern and thereby also form a regular pattern on lower grooves 4, which have a channel-shaped structure on the underside 2 of the elements 1a , 1b, 1c form the insulation board 1. The width of the grooves 4 is 20 mm in this embodiment, the width and length of the projections 3 is about 50 mm.
    2 shows a side view of the insulation board 1 according to the invention, from which it can be seen that the upper side 5 is provided with upper projections 6, which in this exemplary embodiment are also approximately square and are arranged in a regular pattern and thereby form upper grooves 7, which in turn are arranged in a regular pattern and form an upper channel-shaped structure. The insulation board 1 has a step fold 24 on the edge. In this embodiment, the depth of the upper grooves 7 and the depth of the lower grooves 4 are each 15 mm. The thickness of the insulation board 1, measured from the / 31
    The underside of the lower projections 3 to the top of the upper projections 6 is 120 mm in this exemplary embodiment. The side view of the elements 1a, 1b and 1c from FIGS. 1a, 1b and 1c looks like the side view shown here.
    As a possible material for the insulation board according to the invention, for example, a polystyrene rigid foam can be used, which is provided with infrared reflectors and is foam-molded or automatic foam. This material provides an excellent thermal insulation value. Due to the molded part foaming, there is high dimensional accuracy. The insulation board 1 but also the individual elements of the insulation board 1 can have an all-round step fold, so that the individual elements can be assembled to form an insulation board 1 with the highest degree of welding.
    Fig. 3 shows a schematic representation of an existing roof, in which the substructure 19 consists of trapezoidal sheet metal. The roof insulation consists of a vapor barrier 16, an existing insulation 15 and an existing seal 17 arranged on the outside of the roof. If renovation is necessary, the existing seal 17 must be removed or perforated as far as possible. It has proven to be useful that at least five perforation openings 18 are created per square meter of existing seal 17. Longitudinal cuts over the entire length of the existing seal 17 can be produced even more effectively and quickly.
    An insulating plate 1 according to the invention is arranged on the perforated existing seal 17, whereby a dampened existing seal 17 can be dehumidified. This is shown in FIG. 4, the existing roof shown in FIG. 3 in the form of a flat roof being renovated with an insulation system according to the invention.
    As already mentioned, the existing seal 17 is provided with perforation openings 18. The underside 2 of the insulation board 1 is arranged on the outside of the roof given by the existing waterproofing 17. In the case of FIG. 4, the underside 2 of the insulation board 1 is designed as in FIG. 1a. The lower projections 3 are approximately square and arranged in a regular pattern, so that a lower channel-shaped structure in the form of regularly arranged lower grooves 4 is formed, both in the longitudinal direction L and perpendicularly thereto. The channel-shaped structure forms a cavity between the outside of the roof and the underside / 31 of the insulation board 1. In FIG. 4, the roof is shown interrupted in the longitudinal direction. The distance between the ventilation device 8 and the ventilation device 9 is preferably between 10 m and 20 m. Basically, this is possible with an insulating plate 1 designed as a single component, which has both a first through hole 10 for the arrangement of the ventilation device 8 and a second through hole 11 for the arrangement of the ventilation device 9. However, it is preferably provided to assemble a plurality of elements 1a, 1b, 1c here, one element 1a having the through hole 10, one element 1b the through hole 11 and many elements 1c having no through holes.
    The top 5 of the insulation board 1 is designed as in Fig. 1b. The upper projections 6 are also approximately square and arranged in a regular pattern, so that an upper channel-shaped structure in the form of regularly arranged upper grooves 7 is created. These upper grooves 7 form a cavity between the top 5 of the insulation board 1 and a slope insulation 13 arranged thereon. The slope insulation 13 represents a further insulation board, which can consist, for example, of the same material as the insulation board 1.
    The insulation system is connected to the existing roof by means of fastening devices 23. A protective mat or fleece 20 is arranged above the slope insulation 13. This protective fleece 20 can consist, for example, of polyamide or polypropylene. A possible example of such a protective mat 20 is known on the market under the ENKADRAIN® brand. A seal 14 is provided on the outside of the insulation system. These can be bitumen sheets, in particular polymer bitumen sheets. Elastomeric plastic sealing tarpaulins, thermoplastic plastic sealing tarpaulins or liquid plastic are also possible.
    A ventilation device 8 in the form of a ventilation pipe is provided in the first through hole 10. Lower inlet openings 21 open directly into the lower channel-shaped structure, upper inlet openings 21 'open directly into the upper channel-shaped structure. Fresh air can thus flow directly into the cavity on the underside 2 of the insulation board 1 and into the cavity on the top 5 of the insulation board 1. The venting device 9 arranged in the second through hole 11 is / 31
    Vent pipe trained. Lower outlet openings 22 open directly into the lower channel-shaped structure. Upper outlet openings 22 'open directly into the upper channel-shaped structure. The ventilation device 8 and the ventilation device 9 are thus convectively short-circuited with the ventilation channels formed by the upper channel-shaped structure and the lower channel-shaped structure. Air thus flows from the ventilation device 8 via the lower and the upper channel-shaped structure into the ventilation device 9, moisture which is collected in the lower channel-shaped structure and in the upper channel-shaped structure being transported away.
    The air flow is driven by a convection device 12. Such a convection device 12 is, for example, a wind-driven ventilation fan, which is shown in FIG. 5. This fan actively draws air through the system. For example, a fan from MADAC, e.g. B. a fan with the designation V-Master15. This fan has a raw diameter of 155 mm and an average output of 106 m 3 / h with wind force 2 to 4. The fan is selected depending on the area covered by the insulation system and the size of the ventilation or ventilation device 8, 9.
    FIG. 6 shows a schematic, perspective cross-sectional illustration of an insulation system arranged on an existing roof, which is used for the renovation of moisture-damaged existing insulation 15. The perforation openings 18, which are designed as longitudinal sections, can be seen in the existing seal 17. The ventilation device 8 and the ventilation device 9 provided with a convection device 12 are mounted on the outside of the existing roof. The lower inlet openings 21, the upper inlet openings 21 ″, the lower outlet openings 22 and the upper outlet openings 22 ″, which are convectively short-circuited with the lower channel-shaped structure and the upper channel-shaped structure. It can also be seen that the top 5 of the insulation board 1 is provided with approximately square upper projections 6, which are arranged in a regular pattern. The step fold on the broad side of the insulation board 1 can also be seen. Further steps of the insulation board 1 can be connected via this step fold. A slope insulation 13 is arranged above the top 5, since the substructure 19 of the flat roof itself / 31 has no inclination. Subsequently, a protective mat 20 and one
    Foil seal 14 is present, which forms the outside of the insulated roof.
