Parapet means "roof edge upstand as a wall-like structure on the roof edge of a building together with the roof edge closure instead of a gutter".
Parapet drainage is - similar to the gutter drainage - a complete outside drainage for flat roofs. The drainage system is installed near the parapet upstand together with a parapet drain. From there the continuing pipe system is led horizontally through the parapet from the roof.
LORO-X parapet drainage systems in a complete system with downpipe for the main and emergency drainage offer planners and installers a reliable proof of performance in the form of a defined system shape (modular standard systems) and the resulting system performance in the form of a discharge curve. This applies to parapet drainage systems with siphonic flow as well as to systems with gravity flow.
LORO-X parapet drainage systems with siphonic flow constitute an innovative alternative to inside roof drainage systems if the building design does not provide for inside piping systems for the roof drainage. With the pressure-resistant LORO-X steel discharge pipe, all buildings can be drained with siphonic flow via the parapet just as safely as it is known from gravity drainage.
