The warm roof is among the most widespread insulation systems. The warm roof is a compact roof, in which all layers are adjacent and rest on each other. In this solution, which foresees the installation of the panel under a membrane, which, being waterproof, protects it from the weather, the insulation panel manages to maintain its characteristics over time. 

When it comes to ballasted flat roofs, the insulation panel is placed above a structure where the screed is surmounted by a vapour barrier membrane. The insulation panel can be glued, mechanically fixed or simply applied as a dry mortarless layer over the underlying structure. The panels are then covered with a layer of bituminous membrane, which is heat-bonded to the panels through the use of molten oxidized bitumen and being the membrane a waterproof layer it protects the insulation panel and maintains its performance over time. Finally, above the water-tight membrane, a drainage layer of gravel or soil is laid, which also acts as a ballast. 

 

This type of roofing requires the use of insulating panels with high resistance to bitumen solvents, as well as a good resistance to compression. It is to be noted that the application by torching is not recommended.

 

For this application, we recommend the use of SUPERCEL VITRUM. Alternatively, SUPERCEL ALUMEN is also suitable.

6.Bituminous or synthetic membrane

The insulation panel is placed between an underlaying vapour barrier and a bituminous or synthetic membrane: both layers are to be cold-bonded to the panel. This way, the insulating panel is always protected by the water-thight layers and its performance is preserved over time.

 

For this application, we recommend the use of SUPERCEL VITRUM. Alternatively, SUPERCEL ALUMEN is also suitable.

This type of roofing cover is obtained by placing the insulation panel as a dry mortarless layer over the underlying structure - made of a screed and a vapour barrier - and subsequently covered by a waterproof membrane. In order to make this roofing structure suitable for access and walkable, before the paving is laid, it is recommended to cast a layer of reinforced screed above the insulation panels.

The ideal insulation material will have to respond well to compression, ensure good water vapour permeability and present a high-temperature resistance (especially for freezing and thawing cycles).

For this application, we recommend the use of SUPERCEL VITRUM. Alternatively, SUPERCEL ALUMEN is also suitable.

The carriageable roof is a flat drivable roof, characterized by high operating load values. This type of roofing cover is obtained by placing the insulation panel as a dry mortarless layer over the underlying structure - made of a screed and a vapour barrier - and subsequently covered by a waterproof membrane and a thin separating layer - which divides the underlying layers from the overlying reinforced concrete screed. When using this solution, it is necessary to check the extent of the accidental loads and take appropriate precautions. The thickness and reinforcement of the screed will be calculated according to the expected loads and the relative safety calculations.

 

The laying and paving of this roof must be carried out by competent construction technicians and according to the reference standards.

 

For their structural characteristics of compressive strength, SUPERCEL PAPYRUS panel is the most suitable for the insulation of the flat carriageable roofs. Alternatively, SUPERCEL ALUMEN and SUPERCEL VITRUM may also be used.

General recommendations of build up: laying and securing Supercel Building panels. Membrane positioning, general application system.
