Gegenstand der Erfindung ist ein schütt- und maschinell einblasfähiger Wärme-Dämmstoff aus dem Stroh von Getreide fur die Wärmedämmung von Steildächern, Innen- und Außenwänden, Fußböden und Decken im Hochbau.The subject of the invention is a pourable and machine-injectable thermal insulation material made from cereal straw for the thermal insulation of pitched roofs, interior and exterior walls, floors and ceilings in building construction.
Stand der TechnikState of the art
Durch Wärmedämmung von Wohnhäusern sowie von Gebäuden, die eine wohnraumnahe Nutzung aufweisen, lassen sich deren Wärmeverluste entscheidend verringern. Der Umfang der zur Zeit ausgeführten Wärmedämmaßnahmen in Wohnhäusern ist beträchtlich. Man kann davon ausgehen, daß für ein mittleres Haus je m2 Hausgrundfläche etwa 0,4 bis 0,5 m3 Dämmstoff eingesetzt werden. Die Dimensionierung der Wärmedämmungen erfolgt nach der gültigen Wärmeschutzverordnung vom 01.01.95. Die wesentlichen Dämmbereiche in einem Haus sind das Dach, die Außenwände, die oberste und die unterste Geschoßdecke sowie manche Innenwände. Für jeden Bereich haben sich spezielle Konstruktionen herausgebildet, die den Anforderungen am besten entsprechen und den Stand der Technik repräsentieren. Für das Steildach sind das z.B. die Dämmausführungen über, unter oder zwischen den Sparren mit oder ohne Hinterlüftung und für die Außendämmung der Außenwand das Wärmedämmverbundsystem oder die Dämmung unter einer hinterlüfteten Vorhangfassade bzw. Verblendmauerwerk (Kerndämmung).By insulating residential buildings and buildings used as living quarters, heat loss can be significantly reduced. The extent of the thermal insulation measures currently being carried out in residential buildings is considerable. It can be assumed that for an average house, around 0.4 to 0.5 m3 of insulation is used per m2 of floor space. The thermal insulation is dimensioned in accordance with the current thermal insulation regulations of 01.01.95. The main insulation areas in a house are the roof, the external walls, the top and bottom floor ceilings and some internal walls. Special designs have been developed for each area which best meet the requirements and represent the state of the art. For pitched roofs, for example, these are insulation designs above, below or between the rafters with or without rear ventilation and for external insulation of the external wall, the thermal insulation composite system or insulation under a rear-ventilated curtain wall or facing brickwork (core insulation).
Der Dachboden (oberste Geschoßdecke) wird, wenn er nicht begehbar sein muß, durch
einfaches Auslegen eines geeigneten Dämmstoffes und wenn er begehbar sein muß, durch Verlegen des Dämmstoffes zwischen Kanthölzern oder Holzbaiken mit
aufgebrachter Dielung oder Spanplatten gedämmt. Die unterste Geschoßdecke wird bei Neubauten in der Regel von oben unter einer Dielung gedämmt und sonst von unten
mit Dämmstoffen, die eine sichtflächenfertige Oberfläche bieten. Die zur Erfüllung der
Wärmeschutzverordnung erforderlichen ungefähren Mindest-Dämmdicken liegen am Dach bei 100 mm, an der Außenwand bei 80 mm und an der Kellerdecke bei 60 mm,
wenn Dämmstoffe, die dem Stand der Technik entsprechen, eingesetzt werden. In den
aufgeführten Dämmkonstruktionen werden überwiegend Mineralfaser-Dämmstoffe und Schaumkunststoffe eingesetzt. Sie teilen den Hauptteil des Dämmstoffmarktes mit etwaThe attic (top floor ceiling) is insulated, if it does not have to be accessible, by simply laying a suitable insulating material, and if it has to be accessible, by laying the insulating material between squared timbers or wooden beams with floorboards or chipboards applied. In new buildings, the bottom floor ceiling is usually insulated from above under floorboards and otherwise from below with insulating materials that provide a surface ready for viewing. The approximate minimum insulation thicknesses required to meet the thermal insulation regulations are 100 mm on the roof, 80 mm on the outside wall and 60 mm on the basement ceiling.
if insulation materials that correspond to the state of the art are used. In the insulation constructions listed, mineral fibre insulation materials and foam plastics are predominantly used. They share the majority of the insulation market with about
95 % unter sich auf. Dieser h&.in QeutsChländ; zur ZQii"eT:wä einen Umfang von ca. 18 Millionen Kubikmetern pro Jahr. Einen nennenswerten Anteil haben nur diverse Zellulose-Dämmstoffe. Von diesen Dämmstoffen wird gegenwärtig das Niveau derWärmeschutztechnik repräsentiert.95% among themselves. In Germany, this amounts to around 18 million cubic metres per year. Only various cellulose insulation materials have a significant share. These insulation materials currently represent the highest level of thermal insulation technology.
Die Zielstellung der Erfindung besteht darin, den Anteil an Dämmstoffen aus natürlichen und einfach recycelbaren nachwachsenden Rohstoffen am Dämmstoffmarkt zu erhöhen.The aim of the invention is to increase the proportion of insulation materials made from natural and easily recyclable renewable raw materials on the insulation materials market.
Merkmale der Erfindung
Die Erfindung beinhaltet die Herstellung von Fasern aus Getreidestroh in genau solcher
Qualität, daß sie als schütt- und einblasfähiger Dämmstoff verwendbar sind, der nach
Einbringung eine dichte, federnde und fugenlose Dämmung bildet. Zu den Merkmalen
der Erfindung gehört weiterhin, daß die Naturfasern imprägniert werden damit sie nach
DIN 4102 der Baustoffklasse B2 (normal entflammbar) entsprechen und widerstandsfähig gegen Schimmelbildung und Feuchtigkeit sind. Weitere Merkmale
sind, daß der geschüttete oder maschinell in Hohlräume, vorgefertigte Konstruktionen
ein-oder auf freie Flächen aufgeblasene faserige Dämmstoff durch Übereinanderschichten und Verwirbeln der Fasern einen leicht federnden dichten
Strukturverband aufbaut, wodurch eine in sich geschlossene, homogene und fugenlose
Dämmschicht mit reproduzierbarer und gleichmäßig verteilter Rohdichte und deshalb
auch einstellbarer Wärmeleitfähigkeit entsteht, die außerdem nur eine geringe Setzung
zeigt und einen aus reichend hohen längenspezifischen Strömungswiderstand aufweist.
Der dargestellte Dämmstoff wird nach seinem Hauptbestandteil mit der Kurzbezeichnung Strohflex benannt.
Ausführungsbeispiel Features of the invention
The invention involves the production of fibers from grain straw in such a quality that they can be used as pourable and blown-in insulation material, which, once inserted, forms a dense, resilient and seamless insulation. The features of the invention also include the fact that the natural fibers are impregnated so that they correspond to building material class B2 (normally flammable) according to DIN 4102 and are resistant to mold and moisture. Further features are that the fibrous insulation material, which is poured or blown into cavities, prefabricated structures or onto free surfaces by machine, builds up a slightly resilient, dense structural bond by layering and swirling the fibers, which creates a self-contained, homogeneous and seamless insulation layer with a reproducible and evenly distributed bulk density and therefore also adjustable thermal conductivity, which also shows only a small amount of settlement and has a sufficiently high length-specific flow resistance. The insulation material shown is named after its main component with the abbreviation Strohflex.
Example
Die Erfindung wird nachstehend am Beispiel einer der möglichen Zusammensetzungen beschrieben:The invention is described below using the example of one of the possible compositions:
Bild 1 zeigt eine ausgeführte Baukonstruktion mit Strohflex als Einblasdämmung auf der
Innenseite einer Außenwand.
Hierbei besteht die Einblasdämmschicht EDS zwischen der Außenwand A und der Dampfsperre D aus Fasern aus dem Stroh der Gerste mit einer durchschnittlichen Länge
von 15 mm, behandelt mit einem Imprägnat nach Schutzanspruch bei einem Masseanteil
von ca. 20 %. Sie bilden nach Eintrag in eine Dämmkonstruktion eine winddichte, diffusionsoffene und homogene Dämmschicht, deren Dämmwirkung in Abhängigkeit
von ihrer Dicke dem heutigen Stand der Technik entspricht.Figure 1 shows a completed construction with Strohflex as blown-in insulation on the inside of an external wall.
The EDS blow-in insulation layer between the outer wall A and the vapor barrier D consists of fibers from barley straw with an average length of 15 mm, treated with an impregnating agent according to protection requirements with a mass proportion of approx. 20%. After being introduced into an insulation structure, they form a windproof, vapor-permeable and homogeneous insulation layer, the insulating effect of which, depending on its thickness, corresponds to the current state of the art.
