With the height-adjustable parapet drainage for inverted roofs, the strainer unit can be adapted to the thickness of the thermal insulation by moving the triangular upper and lower parts. The triangular shape optimises the flow towards the drain pipe and at the same time minimises the recess in the thermal insulation.

Different LORO-X strainer units can be mounted on the triangular upper part in order to adapt flexibly to different roof build-ups above the insulation layer. Through the triangular lower part, water can also drain from the area below the thermal insulation.

The height-adjustable parapet drain with gravity flow is available in the nominal diameters DN 70 and DN 100.

Advantages

• for height-adjustable thermal insulation on inverted roofs
• maximum insulation thanks to the triangular shape
• minimal thermal bridge
• for inverted roofs made of waterproof concrete or with vapour barrier
• with drainage plate for low paving slabs
• with DRAINLET® hood for smooth surfaces
• with inspection chamber for gravel
