Vertical Parapet Drainage

Drains and pipe penetrations with parapet upstand and vertical outlet

Technical drawing: LORO-X parapet drains and pipe penetrations with upstand and vertical outlet into building interior — Application example for LORO-X vertical parapet drainage - drains and pipe penetrations with parapet upstand for internal downpipes

When the slope of a roof surface is directed outward toward the parapet, parapet drainage systems with lateral outlet and pipe penetration through the parapet upstand with external downpipe are typically used.

In cases where drains or pipe penetrations are positioned at the parapet but the drain pipe should be routed vertically through the roof, LORO offers special parapet drains with upstand for the parapet but with vertical outlet. This way, the downpipe is arranged inside the building rather than outside.

Thanks to the special upstand as a mounting aid, the otherwise usual minimum distance to the parapet for vertical drains without upstand can be eliminated. Sealing is done with the practical clamping flange as a loose and fixed flange construction only on the roof level and not directly in the upstand.

Vertical Parapet DRAINLET and DRAINJET

As main and emergency drainage with gravity and siphonic flow

Technical drawing: LORO-X DRAINLET parapet drain with vertical outlet as main drainage with gravity flow — Main drainage with gravity flow - DRAINLET parapet drain with upstand, vertical outlet for internal downpipe, small wall distance

Technical drawing: LORO-X DRAINJET parapet drain with vertical outlet as main drainage with siphonic flow — Main drainage with siphonic flow - DRAINJET parapet drain with upstand, vertical outlet for internal downpipe, high drainage capacity

As a vertical alternative to the LORO-X RAINSTAR parapet drains, drainage is near the parapet but with a vertical outlet into the interior of the building, like the LORO-X DRAINLET flat roof drains.

Advantages

• Small wall distance to the parapet
• Vertical outlet into the building for internal downpipes
• Secure sealing with clamping flange
• Two-part design for warm roofs

Vertical Parapet Pipe Penetration DRAINLET

Without surface drainage

For this pipe penetration with parapet upstand and vertical outlet, the advantages of the proven LORO-X DRAINLET flat roof drains were combined with those of the LORO-X RAINSTAR parapet drains with upstand.

Advantages

• Small wall distance
• Vertical outlet into the building
• Secure sealing with clamping flange
• Two-part design for warm roofs

Vertical Parapet Pipe Penetration Series H

With surface drainage as direct drain

Technical drawing: LORO-X Series H pipe penetration with parapet upstand and integrated surface drainage as direct drain — Series H pipe penetration with direct drain function - combines pipe penetration with additional surface drainage, vertical outlet, clamping flange sealing

The pipe penetration Series H combines the advantages of the LORO-X Series H balcony direct drains with the secure sealing and upstand of the LORO-X DRAINLET and RAINSTAR drains.

This way, not only the pipe penetration of the downpipe from the upper floors is achieved, but also the additional drainage of the surface with the direct drain principle of Series H.

Advantages

• Pipe penetration with integrated drainage
• Small wall distance
• Vertical outlet into the building
• Secure sealing with clamping flange
• Two-part design for warm roofs

Vertical Parapet Series V-AK

As single drain, direct drain or pipe penetration
