Inverted Heat Insulation in Flat Roof

It is a newer construction methodology with many applications. The insulating layer is found above the sealing and is protected by intense thermal effects. Above the insulating layer lays geo-fabric that filters the water of rain from mud, dust and waste maintaining the passages to the endings of gutters open, but protecting and the insulating layer from the sun.

If the room is not often used therefore accessibility it is not required shingles can be used. If however the roof is often used then the addition of tiles above the insulating layer makes the roof accessible and with the use of spacer in the joints of plates allows the airing and it creates a thin layer of airing between the insulation and the tile. The airing in the roof is essential and particularly beneficial in our country because of the intense and frequent sunlight. It facilitates the operation of heat insulation and prevents overheating.

The inclinations that are required for the flow of waters in the gutters are manufactured above the holder plate and is suggested to be with light weight concrete prepared with special grains of Expanded Polystyrene ISOLBETON in density of 300kg/m3 for the smaller possible cost of construction, but also for additional heat and sound insulation.

In inverted flat roofs we suggest the use of pressed Expanded Polystyrene with very low water absorbance PERIPOR EPS 200 or ISOPOR EPS 200 in the suitable thickness according to the regulation of Energy Efficiency of Buildings.
