A roof web for pitched roofs includes a vapor diffusion permeable but surface water impermeable foil, a reinforcement disposed below the foil, and an open-pore soft foam material disposed below the reinforcement and connected to the foil through the reinforcement, the reinforcement being a tear-proof grid fabric with a diffusion equivalent air layer thickness of substantially 0.07-0.12 m.

Roof web for pitched roofs

The present invention relates to an insulated one-piece roof for use over heatable rooms comprising at least three layers, the first layer being a solid or other load-bearing construction, the second layer being an insulating board and the third layer being a prepared roofing, said one-piece roof further characterized in that the characteristics value .mu..multidot.s where .mu. is the diffusion resistance index and s is the layer thickness of the constituent material of the vertically adjacent layers, decreases outwardly, said prepared roofing being firmly joined to the underlying insulating board and having a characteristic value .mu..multidot.s of less than 4 m.
