Definitions

  • the invention relates to an insulated single-layer roof over heatable rooms, consisting of at least three layers, namely a solid or other support structure, an insulation board and a roofing membrane.
  • a roof is known in which a leveling layer is arranged on a concrete ceiling provided with bitumen paint, on which a vapor barrier layer lies.
  • the actual insulation layer is placed on top, which is then covered with a 3-layer bitumen membrane over a vapor pressure compensation membrane with a single-layer plastic film.
  • the roof structure is weighted with gravel or receives a radiation layer e.g. from grit, slate, etc.
  • the roof structure often used in practice is very complicated and therefore prone to failure. If the vapor barrier layer is not properly laid or subsequently damaged (e.g. by building movements), water vapor penetrates to the roofing membrane, which then bulges upwards as a result of the vapor pressure and can finally tear or, if condensation forms, dampens the structure. It is also disadvantageous that the seals made of loose plastic films (e.g. PVC), which have to be installed due to migration of plasticizers by means of a separating layer, are weighed down by pebbles so that they are not lifted by the wind suction. In addition to the additional gravel, this also increases the cost of the concrete ceiling, which has to be designed more heavily in accordance with the weight percentage.
  • loose plastic films e.g. PVC
  • an insulating plate which consists from the outside inwards of a water-impermeable layer, a foam layer and a water vapor-retardant layer (vapor barrier), the water-impermeable layer having a greater water vapor permeability value than the water vapor retardant layer.
  • the invention has for its object to find an insulated 'single-skin roof that is easy to manufacture from prefabricated parts, requires no additional load against lifting, is sealed against surface water and, despite the absence of a vapor barrier on the underside, has no blistering of the roofing membrane as a result of water vapor diffusion.
  • This object is achieved according to the invention in that a separate layer, which acts as a vapor barrier, is missing, and in that the parameter / L .s with Iz as the diffusion resistance number and s as the layer thickness of the building materials of the layers lying one above the other decreases from the inside to the outside, with the exception of the The area of the overlap with the insulating foam panels arranged underneath and firmly connected to the roofing membrane with a parameter smaller than 4 m, in particular smaller than 1.5 m, is designed to be tight against surface water.
  • the roofing membrane consists of polyglycol ether urethanes with an elongation at break according to DIN 53504 of at least 120% and a diffusion resistance number of at most 4000.
  • a roofing membrane on this basis maintains a high elongation at break even in the low temperature range, which is particularly advantageous for roofs.
  • a further advantage is that, due to the blocking of free isocyanate groups, there is no sensitivity to moisture in the manufacture of the roofing membrane, and the formation of CO z gas bubbles in the roofing membrane is therefore ruled out.
  • polyether glycols known per se in polyurethane chemistry in particular polypropylene glycols in the molecular weight range 500 to 6000, preferably 2000 to 4000, with excess amounts of organic diisocyanates, for example 2,4-diisocyanate toluene, the mixtures thereof with 2,6- Diisocyanate toluene or 4,4'-diisocyanate diphenylmethane to give the corresponding NCO prepolymers with terminal isocyanate group contents of 0.5 to 6.0%, preferably 1.5 to 3.5% by weight, and then converting the NCO- Prepolymers with phenols, preferably C 4 -C 12 alkyl phenols such as 4-tert-butylphenol, isononylphenol or dodecylphenol reacted with blocking the free isocyanate groups.
  • organic diisocyanates for example 2,4-diisocyanate toluene, the mixtures thereof with 2,6- Diisocyanate toluene or
  • Suitable crosslinking agents for the resulting polyglycol ether urethanes containing carbamic acid arylester groups are any organic polyamines having at least two primary and / or secondary amino groups. Particularly suitable polyamines are, for example, cycloaliphatic diamines.
  • the reactants are generally used in stoichiometric amounts, but an up to 15% overdosing or underdosing of the amine is acceptable.
  • the reaction of reactants a) and b) is preferably carried out in the temperature range between 10 ° and 150 ° C.
  • the insulation panels consist of closed-cell PUR foam.
  • the insulation panels consist of strips which are connected in the factory by the roofing membrane.
  • This runway which may have an inclination even as a result of different thicknesses, covers larger areas, and, as with the panels, the roofing sheet can overlap on certain sides for overlaps.
  • the insulation materials are glued to the roof surface using the known adhesive techniques, e.g. Hot bitumen or cold glue or with mechanical fastening without gluing possible.
  • the bonding of the polyurethane sealing sheets to one another is to be connected using the known adhesive techniques; it is particularly advisable to use a one- or two-component polyurethane reaction adhesive mixture here, since it has the same property profile as the sheet.
  • the glass viies (paper) intermediate layer 2 which is located on the underside from the prefabrication, is glued directly to the polyurethane insulating plate 3 on a solid construction 1 made of reinforced concrete, while a protruding roofing membrane 4 made of blocked polyisocyanate is attached in situ on the upper side. which can move freely at the edges by paper strips (drag strips) 5, even after the overlap 6 of the adjacent roofing membrane has been connected.
