For this it is particularly beneficial if the indentations Inner and collecting ducts are straight-line ducts, each in run at right angles to each other.

The insulation core is expediently made of foam, in which the channels are milled. The depressions on the upper side of the core can preferably be through a cork pellet ventilation cardboard as.

To achieve one thing if possible large cross-section for the Samriel canals, the collecting canals of adjacent V / ärmeaämmplatten cover each other and in the roof verbana to the edge of the roof form continuous open-ended drainage channels. . -.
