Conventional Flat Roof Heat Insulation

It is the most common type in our country. It is a one shell constriction with main characteristic the placement of sealing layer overlying the insulation so that it protects it from waters of rain, it remains however exposed in the meteorological phenomena and in hot Greek sun. The insulating layer is usually placed above the holder plate or above the layer of bents. In flat roofs is preferable the insulating layer to be placed above the plate, and not under it. In such way we achieve the exploitation of thermal capacity. The thermal strain of the plate is of course limited and allows, during the summertime, the achievement of a more comfortable internal climate.

In conventional flat roof Expanded Polystyrene can be used with graphite such as NEOCOAT TX EPS100, NEOPLAK TX EPS 100, and ISOPOR EPS 150 in suitable thickness according to the regulation of Energy Efficiency of Buildings. The inclinations that are required for the flow of waters in the gutters is proposed to be fixed with light weight concrete prepared with special grains of Expanded Polystyrene ISOLBETON in density of 300kg/m3 for the smallest possible cost of manufacture, but also for additional heat insulation.

As final layer the choices of the materials depend on the usage of the roof. It can be accessible or not and the accessibility depends on the frequency of use.
