Account: Darmstâdter Volksbank e. G. mb H., Darmstadt, No. 119 this water vapor on the cold underside of the roof cladding, causing condensation and thus moisture damage.

Most of them installed on the concrete ceiling under the thermal insulation layer So-called vapor barrier made of roofing felt embedded in hot bitumen or the like prevents only in a very good and expensive design and with a low relative moisture content the indoor air the diffusion damage. The vapor barrier has the disadvantage that the building moisture the concrete ceiling cannot escape upwards and is also the cause of a perpetual new charging of the ceiling resp. Wall plaster and the concrete ceiling with Moisture in the event of a change in climatic which is possible at any time or intermittently Room conditions. In rooms with high relative humidity z. B. strong occupied lounges, school rooms, bathrooms, production rooms with operational conditional high humidity, etc., this method fails completely. tried silane often the inconvenience to remedy that between the concrete ceiling and the thermal insulation layer a sturdy cardboard is inserted, the small channels of which with the outside air in Connect to a pressure equalization and a discharge of the diffused moisture to enable. This process is expensive and requires official orders a reinforcement of the insulation layer, as the insulation effect due to its ventilation is reduced.

The purpose of the invention is to provide a remedy here in an expedient manner. jjr is achieved by creating flat building boards that are as water vapor permeable as possible and at the same time heat-insulating materials of sufficient compressive strength and are factory-fitted with ventilation ducts on one level. These ventilation ducts are on roofs upwards - towards the roof skin - on walls towards the cold side arranged.

The building boards can be produced e.g. B. from steam-hardened Aerated concrete, lightweight concrete of all kinds, e.g. B. Foam-barren expanded concrete, expanded and cork pieces bound with bitumen, pieces of plastic hard foam bound with suitable binders, impregnated peat, mineralized and with binding agents, e.g. B. cement bonded Wood wool or wood chips, impregnated or bituminized wood fiber or the like.

When using these substances and at the same time training the Ventilation ducts, the arrangement of a special ventilation element is no longer necessary.

Before applying the roof membrane, this can be done in any usual way can, the z. B. 4 cm wide and 2.5 cm high ventilation ducts of the panels on the construction site beforehand with sufficiently stable, flat and relatively thin panels from z. B. hard fiber, wood fiber, asphalt, asbestos cement or the like covered and by means of suitable adhesives, e.g. B. Hot bitumen attached to the webs of the building board these panels to be glued on have been selected to be about 3 mm thick, this construction is included Two to three layers of glued roofing felt can be walked on for repair purposes. With larger Strength is the resilience a correspondingly higher.

The ventilation ducts of the building board closed in this way at the top must be in contact with the outside air at both ends in order to equalize the vapor pressure and to ensure the dissipation of diffusing moisture without reducing the strength to have to increase the thermal insulation layer.

The dimensions of the building panels (length and width), in rows are placed next to and behind one another on the roof surface, depend on the substance to be used and its transport weight. The strength of the panels is variable according to the desired insulating effect. Also the height and width of the bars between the ventilation ducts can be different according to the desired cross-section are executed. The building panels can also be reinforced by means of steel or steel Wooden inlays are made capable of bearing loads, so that a Laying over purlins is possible.

The drawings show in Fig. 1 the isometric representation of the heat insulating. Ventilation panel, in Fig. 2 the view of an area covered with ten pieces of panels, with additional ventilation ducts being entered at an oblique angle to the main ducts in two panels, an application example for a roof in FIG. 3.

Here mean: a = ventilation ducts, b = the webs between the ventilation ducts, c = the height of the webs, d = the thickness of the building board without webs, e = the length of the Building plate and f = its width.
