Description
Rubber Roof UK complete horizontal drain kit for EPDM flat roofs that discharge sideways through a parapet wall, fascia or upstand into a hopper or box gutter. Everything needed to form a watertight through-wall outlet is included – the drain, the leaf grate, the uncured flashing tape and the primer to seal it.
What’s in the kit
- 1 × horizontal drain outlet with EPDM flange and horizontal spigot for standard downpipe fittings
- 1 × leaf grate
- 1 × 500mm length of 9-inch (225mm) uncured EPDM flashing tape
- 1 × EPDM primer
How it fits
Fix the outlet through the wall (hole size 105mm × 105mm), dress the membrane over the flange, prime the lap and seal it with the supplied uncured flashing tape for a flexible, watertight seal that stays secure under thermal movement and heavy rain. The fitted leaf grate limits debris and blockages.
Ideal where an internal (vertical) outlet isn’t possible. One complete kit is needed per outlet – the roof kit calculator adds one automatically for every horizontal drain you enter.
