Definitions

  • the invention relates to a fire protection membrane with a vapor barrier for covering roof and wall surfaces and the like with a load-bearing membrane and a flame-retardant membrane made of a non-woven glass fiber and containing crystalline-bound water.
  • fire protection membranes are installed on roof constructions and membranes that are not «hard roofing» in the sense of DIN 4102 and therefore not resistant to flight fire and radiant heat. With these fire protection membranes you can achieve the desired «hard roofing».
  • the fire protection membranes are placed between the insulation and an upper layer. They are mainly used for plastic films or high polymer sheets. An example of a "hard roof” achieved in this way is described in DE-A-3 220 821.
  • EPS rigid foam is mainly used as the insulation material.
  • EPS means expanded polystyrene.
  • Polystyrene is a thermoplastic. In terms of wind load, moisture absorption, elasticity, value for money and good installation options, this synthetic foam is the optimal solution.
  • thermoplastics laid on insulating steel sheets behave particularly favorably in the initial phase of a fire.
  • they sinter or melt and absorb heat. This delays the transfer of heat to the steel profile sheet. It is said that the temperature flows upwards. If the fire persists, however, the roof skin is subjected to greater stress. If the insulation material burns or disappears, the temperature will break through. If the fire lasts longer, the surface may burn.
  • the steel profile sheet collapses, it makes no difference whether a melting thermoplastic or a non-melting material was used as the insulation material.
  • the object of the present invention is to develop a roofing membrane which forms both a fire protection membrane and a vapor barrier.
  • the fire protection membrane should be equipped in such a way that in the event of a fire from below, burn-through until the steel profile sheet collapses is reliably prevented.
  • the solution to this problem according to the invention results from the fact that the supporting sheet is an aluminum foil, plastic foils are laminated onto both sides of the aluminum foil, and the glass fiber fleece containing crystalline water is laminated onto one of the plastic foils and is coated on its free surface with a wax layer.
  • the glass fiber fleece, which contains the crystalline water is designed, for example, according to DE-A-3 220 821.
  • This fire protection membrane with vapor barrier according to the invention is laid over the load-bearing roof structure, for example with steel profile sheet, and under the insulation membrane.
  • the wax layer applied to the free surface of the glass fiber fleece is water-repellent but permeable to water vapor. This ensures that the water bound in the glass fiber fleece or the fire protection agent is not washed out during installation on the construction site. With this feature, sufficient moisture security is achieved for the laying time on the construction site. It should be mentioned that the fire protection membrane according to the invention can and should be covered with additional membranes immediately after it has been laid.
  • the plastic film laminated onto the underside of the aluminum foil expediently consists of polyester, while the plastic film laminated onto the upper side consists of polyethylene.
  • the fire protection membrane according to the invention When the fire protection membrane according to the invention is laid on a profile sheet, the profile spaces which are then left free can be partitioned off.
  • rods or cubes made of plastic foam can be inserted into them. These bars or cubes close the profiles or beads of the profile sheet. This prevents flammable gases, smoke and the like from continuing to flow and spread.
  • the rods or cubes consisting of a plastic foam are expediently soaked with a fire protection agent.
  • the use of such rods or cubes made of plastic foam for closing the profile cavities or beads of the profile sheets is known per se.
  • the use of these cubes or rods is new in the fire protection membrane according to the invention. It is also new to treat or soak these cubes or rods with a fire protection agent.
  • the remaining free profile cavities can also be sealed off with sand or gravel. This is simply poured into the profile cavities.
  • the fire protection membrane according to the invention has a high tear resistance. It can therefore be laid on steel profile sheets or trapezoidal steel sheets and over their beads. It is protected against corrosion by the thin polyethylene foils.
  • the fire protection membrane according to the invention can be stuck on with a bitumen cold adhesive which itself brings only few flammable components onto the roof. The overlaps between adjacent fire protection membranes can also be glued with a bitumen cold adhesive. For special fire protection requirements, the fire protection membrane can also be nailed on. The entire layer package including the first layer of the roof skin is nailed on.
  • the fire protection membrane on top releases approximately 200 g of water per square meter as a result of the water crystallized in the glass fiber fleece. This leads to larger amounts of water vapor. This water vapor fills the caverns of the thermoplastic material, which have resulted from the temperature radiation from below, so strongly with water vapor that burn-through is no longer possible.
  • the fire protection membrane according to the invention can, as stated, be laid directly on steel profile sheets, such as steel trapezoidal sheets. It can also be placed on other substructures requiring fire protection. It forms the vapor barrier necessary for building physics reasons and at the same time prevents burnout, as stated.
  • Fig. 1 shows the steel profile sheet 12, which is a trapezoidal sheet.
  • the fire protection membrane according to the invention lies on this. This includes the aluminum foil 14 and the plastic foils 16 and 18 laminated on both sides thereof.
  • the glass fiber fleece 20 is laminated onto the plastic foil 16 lying on top. This is treated with a fire protection agent and / or enriched with crystalline water.
  • the cavities or beads of the trapezoidal sheet 12 are designated by 24.
  • cubes or rods 26 made of plastic foam are located in these beads.
  • These rods can also be treated with a fire protection agent or contain crystalline water. As stated, they prevent smoke and flammable gases from flowing through the beads 24 in the event of a fire and thus being distributed in the building and the roof structure. 3, small piles 28 of gravel or sand are filled into the beads.

Abstract

La voie pare-feu est posée en plus des voies de toit et d'isolation habituelles sur un pan de toit. Elle doit empêcher le développement d'incendies en nappe ou au moins les retarder. Elle doit former simultanément une barrière de vapeur. A cet effet, elle contient deux feuilles de plastique entourant une feuille d'aluminium servant de voie porteuse. Un non-tissé de fibre de verre avec une certaine teneur en eau à liaison cristalline est contre-plaqué sur une feuille de plastique. L'eau se vaporise en cas d'incendie. La vapeur d'eau qui en résulte empêche ou retarde un incendie en nappe ou un incendie total.
