    Technical area
    The present invention relates to an insulation panel for a rafter insulation system for insulation of a sloping roof structure having the features of the preamble of claim 1. Furthermore, the invention relates to a rafter insulation system comprising such a panel and a sloping roof with such a rafter insulation system ,
    Technical background
    Savings insulation systems that are arranged or installed above the static elements of the roof construction and in particular above the rafters are known. This type of insulation can be used both in new constructions and in the renovation of old buildings. In this system, the roof cover (brick and the like) is disposed above the insulation members. The insulation above the rafters offers important benefits in terms of avoiding thermal bridges compared to insulation wedged between the rafters. In particularly efficient installations, the insulation above the rafters is used in combination with the insulation between the rafters. In this case, the rafters responsible for the thermal bridges are covered with the insulating material. On some occasions, by using the appropriate insulation above the rafters, the builder can completely dispense with the insulation between the rafters, resulting in an improved visual appearance of the space seal in the case of rafters visible from the inside.
    Isolation elements for insulation above the rafters are typically formed from a mineral wool material (e.g., glass wool or rockwool) shaped as panels (rectangular parallelepiped). The two larger parallel flat surfaces form an upper surface and a lower surface of the insulation panel. The panels further have two lateral sides and two longitudinal sides which respectively define the width and the length of the panel, two of which are mutually parallel and which are perpendicular to the larger lower and upper surfaces.
    In the prior art, it is known that the upper surface of the panels is provided with a membrane, as described for example in DE 19 922 592 A1. The membrane, for example, covered by a polymeric non-woven such as e.g. A polyester nonwoven fabric is laminated to the top surface of the panel by an adhesive applied in the form of a dot or striped pattern coating. This membrane is impermeable to water, but it is open for the diffusion of water vapor at a certain rate. The membrane, which is also referred to as a vapor barrier or vapor barrier membrane, serves to protect the panel against the penetration of water from its upper outer surface.
    According to the usual construction methods, a plurality of insulation plates are arranged with their lower surface in the vicinity of the rafters, either in direct contact with them or alternatively via a wood cover layer which is arranged on the rafters. The panels are arranged in abutment with each other so as to cover the entire area to be insulated, forming a continuous insulation layer. This type of construction is described, for example, in DE 19 922 592 A1.
    In this type of construction, the technique further recognizes the possibility that the water vapor membrane has a width and a length which is larger than the width and the length of the panel. Thus, it can be achieved that the vapor barrier membrane projects beyond a longitudinal edge and beyond a widthwise edge of the panel. In this embodiment, when the panels are installed, the membrane laminated on one panel overlaps two other adjacent panels. These overlapping protruding portions of the membrane are then preferably attached to the respective membranes of the adjacent panels, for example by staples or adhesive. Thus, a water and wind impermeable continuous layer is achieved on the insulation panels, which acts as a roof pad. An example of this type of arrangement is described in DE 3 615 109 C2.
    The insulation panels may be subjected to mechanical stress during or after installation due to roof assembly work, such as attaching a slatted formwork or covering by bricks. The mechanical stresses are caused, for example, by missteps of the construction workers or by the dropping of tools or construction components. It is therefore necessary that the insulation panels can at least temporarily survive such point loads.
    Various methods are known in the art to increase the mechanical compression resistance of mineral wool. One possibility is to increase the mineral wool density and / or the panel thickness. Although this increases the rigidity and compression resistances of the panels, this leads to higher material consumption and the level of density / thickness is often limited by the production line capabilities, especially in the case of glass wool production. This "densification" of the glass wool materials is usually achieved by forming a primary fiber mat with a non-cured binder material and by applying compression in the thickness direction of the mat, reducing it several times in thickness before the resin in the mat has cured and the final thickness is set. Thus, in order to achieve high densities and high thicknesses in the final products, the primary mat would have to be made with a very high thickness, which is often not possible in the glass wool production lines.
    Another technique for increasing the mechanical stiffness of the mineral wool panels is to align the mineral fibers within the panel in the direction perpendicular to their upper and lower surfaces. Two such techniques have been extensively described, commonly referred to as lamella panel formation and crimping. In the first one, the cured mat is cut into strips (slats) as manufactured and then rotated 90 ° and then reconnected to form a panel. This rotation of the strips realigns the fibers, which are originally in parallel alignment with the top and bottom surfaces, perpendicular to them. In the crimping process, the uncured mineral wool mat is subjected to successive longitudinal compression by pairs of conveyors that run sequentially at lower speeds. The longitudinal compression creases and re-aligns the fibers before the binder hardens and sets the new orientation. Although these techniques have been shown to be effective in increasing the compression resistance of the obtained panels, they often result in a great reduction in their thermal insulating property.
    Disclosure of the invention
    The present invention is therefore directed to an improved insulation panel for use in a rafter insulation system for isolating a sloped roof which aims to overcome the limitations and deficiencies of panels known in the art.
    The object is solved by a rafter insulation panel having the features of claim 1, a rafter insulation system having the features of claim 12 and by a sloping roof having the features of claim 13. Preferred embodiments follow in the other claims.
    Throughout the description, top and bottom are relative terms that designate the position relative to the ground of the elements when the panels are installed in the roof construction. Thus, the upper surface is above the lower surface when the panel is installed. The upper surface is directed towards the outside of the building, while the lower surface is directed toward the interior of the building.
    The inventive insulation panel has an insulation core with a certain thickness. The panel also provides an upper surface and a lower surface substantially parallel to the upper surface, as well as two lateral sides and two longitudinal sides each defining the width and length of the upper and lower surfaces and forming the width and longitudinal edges of the core , The panel is further provided with a first web, preferably made of glass fibers, laminated to the upper surface of the insulator core. The first nonwoven preferably completely covers the upper surface of the insulation core. The panel also includes a vapor barrier membrane which is laminated to and covers both the first nonwoven and the top surface of the insulator core, and having a width and a length each greater than the width and length of the core. Thus, the diaphragm protrudes at least beyond an edge in the width direction and an edge in the longitudinal direction of the core. Preferably, the vapor barrier membrane is laminated with an adhesive, referred to in this specification as a second adhesive, to the first nonwoven disposed on the top surface of the insulator core. In other words, the vapor barrier membrane is indirectly laminated to the insulation core by inserting the first nonwoven fabric by applying a second adhesive between the membrane and the nonwoven fabric.
    In the inventive panel, the insulating core has at least two glass wool plates having a thickness smaller than the thickness of the core. Each of the at least two glass wool plates is provided with further fleeces laminated on the surface or surfaces of the plates opposite to the other plate or plates. In other words, the surfaces of the glass wool panels to be laminated to each other are provided with other fleeces. The glass wool panels are laminated to each other at their opposite surfaces by an adhesive, which is referred to as a first adhesive, with the insertion of the other nonwovens. In other words, the glass wool plates are indirectly laminated to each other at their opposite surfaces, which were previously covered by the other nonwovens.
    The glass wool sheets provided in the core of the panel can be made by ordinary glass wool manufacturing techniques with increased density and thus with increased rigidity and compression resistance. Since the plates have a thickness smaller than the total thickness of the insulator core, they can be manufactured without problem, overcoming the limitations of density / thickness of glass wool production. To obtain panels of greater thickness, for example more than 100 mm, as required for some rafter insulation applications, a plurality of panels may be laminated together. The total insulation core thickness is then a sum of the thicknesses of the individual plates plus the thicknesses of the other nonwovens.
    The glass wool should be understood as a collection of several interwoven glass fibers of different lengths connected by a cured polymer resin at their crossover points. One skilled in the art can easily identify the properties that make up a mineral fiber composition and a glass fiber composition, and can distinguish a glass from other materials. As a simple distinguishing feature, the term glass fiber means that the mineral fiber composition of the fibers is characterized by an alkali / alkaline earth ratio greater than 1. In comparison, rockwool fibers have an alkali / alkaline earth ratio of less than 1.
    The glass fibers constituting the glass wool plates contained in the insulating core of the panel of the embodiments are bonded by cured resins. The type of resin is not limited. It is preferred that the resin used is a thermosetting resin, such as those already known in the art. Non-limiting examples are phenol-formaldehyde resins, acrylic resins, polyester resins made by a reaction between polyols and organic polybasic acids, Maillard type or carbohydrate-based resins, or inorganic resins such as colloidal silica, silicates, phosphates, and mixtures thereof. These resins are preferably applied to the glass fibers as aqueous compositions, which are produced by a Faserherstelleinrichtung before they are collected and compacted on the receiving feeder. In a subsequent step, the resins are cured to cause the thermosetting reaction and to join the fibers at their crossover points.
    The resin content of the glass wool fibers, which is measured as loss on ignition (LOI) according to ISO 29 771: 2008, can be chosen so that it further contributes to the increase in the rigidity and mechanical resistance of the plates. In embodiments, the LOI of the plates is preferably greater than 4 weight percent, based on the total weight of the glass fibers, preferably between 4 and 12 weight percent and even more preferably between 6 and 10 weight percent.
    The average fiber diameter of the glass wool panel (calculated from an optical microscopy analysis) is less than 15 microns, preferably less than 10 microns, and even more preferably in the range of 4 to 8 microns.
    Preferably, the glass wool panels have a laminar orientation of the fibers. A laminar glass wool plate is understood to mean that the fibers forming the glass wool plate are mainly directed parallel to the major surfaces of the plate and the panel. The laminar alignment of the fibers results from depositing the fiber, freshly formed by a fiberising means, onto a receiving feeder with suction of air from beyond the receiving feeder. In the laminar glass wool panels, the fibers have not been subjected to a process of increasing their orientation perpendicular to the major surfaces of the panel, such as lamella formation or crimping.
    The laminar orientation of the fibers in the glass wool panels increases the thermal insulation properties of the panels in their thickness direction.
    The thickness of the plates is preferably in the range of 40-80 mm and the density in the range of 40-80 kg / m 3. Preferably, the final thickness of the insulating core is in the range of 120-200 mm and is obtained by laminating 2 or 3 glass wool plates together.
    The glass wool plates are preferably rectangular Parallelepipedformen. The lengths of the plates are preferably in the range of 1000 mm to 3000 mm, more preferably in the range of 1800-2200 mm. The width of the plates is preferably in the range of 300-900 mm, and more preferably in the range of 500-700 mm.
    The panel is further provided with a vapor barrier membrane laminated to the first web, i. E. the nonwoven fabric disposed on the upper surfaces of the insulation core. The membrane is impermeable to water, but water vapor and other gases can diffuse through it at a certain rate. Preferably, the vapor barrier membrane is a polymeric nonwoven film. More preferably, the vapor barrier membrane is a multi-layer polypropylene nonwoven film. Preferably, the thickness of the membrane is in the range of 400-1000 microns and its surface weight in the range of 100-300 g / m 2. The membrane preferably has a sd permeability for steam, measured according to DIN EN 12572, in the range of 0.02-0.08. Commercial products suitable as a vapor barrier membrane are, for example, SECO PRO 0.04 from Ursa Insulation.
    According to the embodiment, the membrane is provided with a width and a length each greater than the width or the length of the insulation core. The membrane is laminated to the first nonwoven disposed on the top surface of the insulator core such that the membrane covers the entirety of both the first nonwoven and the insulative core and also protrudes beyond one of the side edges and one of the longitudinal edges of the core. The parts of the membrane that protrude beyond the edges of the insulator core are intended to partially cover the adjacently disposed panels when the panels are installed in the roof and to seal the insulation system from the top, so as to seal the insulation system from above continuous roof underlay.
    The protruding parts of the membrane beyond the insulation core preferably have a width in the range of 5-20 mm, more preferably in the range of 8-15 mm, to ensure a good seal when the panels are installed with overlapping membranes.
    Advantageously, the parts of the membrane which protrude beyond the edges of the glass wool core are further provided with an adhesive, which for reasons of clarity will be referred to as the third adhesive from now on, for example in the form of a strip along the length of the protruding part. The third adhesive is preferably a pressure-sensitive adhesive. This third adhesive is intended to secure the protruding part of the membrane to the membrane of an adjacent panel during installation. The adhesive is preferably protected by a release layer prior to use. A first fleece, preferably a glass fiber fleece, is laminated to the upper surface of the insulation core. The first nonwoven fabric is thus arranged between the insulation core and the vapor barrier membrane. The first web is preferably laminated directly onto the glass fibers of the core by any method of the prior art. However, it is preferred that the nonwoven be adhered to the glass fibers with the same resin as used for bonding the fibers of the glass wool plate. Particularly preferred is the application of the nonwoven fabric to the uncured glass wool mat during the manufacture of the panels and the subsequent introduction of both the glass wool mat and the nonwoven fabric into a curing oven to cause the bonding of the glass fibers of the glass wool mat and the nonwoven by the cured resin.
    Each glass wool panel, which is provided in the insulation core is provided with further nonwovens, preferably glass fiber webs, which is on the surface or the surfaces of the plate, which are to be laminated with the other plates, laminated. The further nonwoven layers can be laminated to the glass wool plates by the same procedures described in the previous section. The further nonwovens may be similar to or different from the first nonwoven provided between the insulator core and the membrane. Preferably, all nonwoven layers have a similar structure and properties.
    In the embodiments, the first and further nonwovens are preferably glass fiber webs. Such fiberglass webs are made of glass fibers having a defined fiber diameter and fiber length which have been randomly deposited and which are bonded to a binder. Reinforcing fibers can be incorporated into the nonwoven structure to increase dimensional stability. The thickness of the first and further nonwovens is preferably in the range of 100 to 700 micrometers. The surface weight of the first and further nonwovens is preferably in the range of 20-100 g / m 2. The tensile strength in the machine direction and in the transverse direction of the first and further nonwovens is preferably in the range of 100-300 N / 5 cm and 50-250 N / 5 cm, measured according to DIN EN 29 073-3: 1 992-08. Examples of useful commercial fiberglass webs are those of the Evalith® brand from Johns Manville.
    The presence of the nonwoven layers, both the first nonwoven layer and the further nonwoven layers, has the advantage of increasing the resistance to stresses, such as tensile stresses, and to selective compression forces of the insulation panel, as a result of the distribution of forces through the surface thereof. In addition, they improve the bond strength achieved by the adhesive lamination of the various panel components and reduce the amount of adhesive required by providing a smoother, less penetrable and more homogeneous surface than the glass wool panels.
    In further embodiments, the panel is provided with an additional non-woven in the lower surface, namely the surface which is closer to the rafters when the panel is installed. This additional nonwoven fabric is preferably a fiberglass mat and improves handling of the panel, reduces the release of loose fibers and dust from the core, and further contributes to improved mechanical resistance.
    The membrane is preferably laminated to the top surface of the insulation core and to the first nonwoven laminated to the top surface of the core, preferably with a second adhesive. This second adhesive can be any of the prior art adhesives, such as a polyolefin hot melt adhesive, reactive polyurethane, and the like. Preferably, the second adhesive is a reactive one-part polyurethane.
    In preferred embodiments, the second adhesive is applied in an open pattern by any known technique, such as spraying, troweling, direct or transfer coating, so as not to hinder the water vapor permeability through the adhesive layer. Preferably, the adhesive is applied as separate strips or tapes of a certain width and is cured after the membrane and the insulator core carrying the mat have been bonded together. The amount of second adhesive that is applied must be sufficient to maintain sufficient bond strength between the membrane and the first web and / or core and to avoid delamination during handling, installation or use of the panel.
    The glass wool panels are laminated together using a first adhesive to form the insulation core. This first adhesive may be any of the adhesives mentioned above with respect to the second adhesive used to laminate the membrane to the first nonwoven, and may be applied by similar techniques. It is also preferred that the first adhesive be applied in an open pattern, more preferably in the form of separate strips or bands. Similarly, the amount of first adhesive that is applied must be sufficient to maintain sufficient bond strength between the laminated panels and to avoid delamination during handling, installation or use of the panel. As above, the preferred first adhesive is a reactive one-part polyurethane.
    Preferably, the glass wool plates contained in the core have similar dimensions and are arranged in alignment of their lateral and longitudinal surfaces, which means that their longitudinal surfaces and their side surfaces are each contained substantially in the same plane.
    In alternative, preferred embodiments, the glass wool panels are arranged at mutually displaced positions, so that an insulation core is formed with a stepped or Stufenfalzkanten. The step seam edges result in the further advantageous prevention of thermal bridges when the panels are arranged side-by-side, as is customary in the target application as a rafter roof insulation. In comparison, thermal bridges can potentially be formed between adjacent straight edges of the adjacent panels.
    The invention also relates to a rafter insulation system comprising an insulation panel according to the embodiments. In preferred embodiments, the rafter insulation system includes a plurality of insulation panels disposed adjacent to other panels, engaging the lateral and longitudinal insulation core edges, such that a continuous layer of insulation panels is formed. This continuous layer of juxtaposed panels advantageously extends to cover the entire roof area to be insulated. In the built-in insulation system, the vapor-permeable membrane of each of the adjacent plurality of insulation panels is arranged so that their protrusion portions overlap with the adjacent panels.
    The invention also relates to a pitched roof having the rafter insulation system described above. The sloped roof installation is completed by an additional water-impermeable membrane disposed between the rafters and the insulation panels, by wooden slats and counter-slats disposed on the insulation panels, by double-threaded screws for securing the slats and counter slats to the rafters, and by the roof tile covering ,
