【正文】 ceiling structure can take the load. Naturally the root resistance protection needs to be dealt with. Basically there are two types of root protection. In the separated type of root protection system the membrane is not root resistant, but the FLL resistance test’s four year test period has not been pleted to date, and for this reason, it is temporarily used with a separate root protection layer. Therefore, in the case of a separated system of root protection, the root protecting layer is placed on a distinct level. In the case of an integrated root protection system, the waterproof membrane itself is proven to be root resistant, so additional 12 protection is unnecessary. For conventional ?at roof solutions, the vapor load ing from beneath must be blocked, since the usual ventilation of vapor barrier is hardly possible, and from an aesthetic point of view, ventilation pipes are to be avoided. For . type solutions, the waterproo?ng membrane is underneath the insulation and there is no vapor barrier layer. This way there are less layers and the construction technology is simpli?ed. As is generally known, only closed cell extruded hard polystyrene foam thermal insulation is to be used (Roommate), with inset and truss in one layer. Compared to the construction of the conventional builtup roof, about a 20% thicker thermal insulation should be used, due to the moistening of the insulation surface, and the cooling effect this causes. A requirement regarding the load carrying roof structure is the proper heat retaining capacity, with a steelcement structure roof mass of 250kg/m2 minimum criterion. Above the thermal insulation the other layers should be installed with materials suitable for ventilation and diffusion of vapors. In choosing the green roof construction solution with insulated roof membrane application, the rising tendency of the insulation should be considered, and therefore a shallow extensive roof might present an obstacle. With dual insulated ?at roofs, the waterproo?ng is positioned at the bottom layer which is cheaper and has a poorer quality, and then, after the possibly required root protection layer, es the top insulation layer, which has to have the same quality as the . Here there is less danger of rising then with the insulation of ., here too it should be considered. If the dual insulated roof is new, then the vapor barrier layer is omitted (with engineering approval). If the dual insulated roof is used in the renovation of roof insulation, then naturally, the original layers could contain a vaporblock and vaporpressure equalizer layer too. In the renovation of old roof insulation。 the lighter extensive green solutions are advisable, since generally the load capacity limits have to be considered. In these cases the use of thin sod or a precultivated vegetation cover would be suitable, with periodical care, considering the climate of Central Europe. 3 SUMMARY For those future home owners, architects, and builders who accept and assert the views of ecological architecture, the green roof system provides the chance to contribute to an aesthetic 13 and healthy environment with the creation of roofs planted with green vegetation. The technical and landscaping requirements are available for the construction of grassy roofs and roof gardens。 the only thing needed is that action follows the words and planning, so that with human constructive capabilities, the areas taken from nature are made to e alive again in our immediate environment
