Product info

The Manthorpe Flash Vent is a simple one-piece roll-out, easy fit sheet that provides ventilation for abutment roof details, providing a weather-tight solution to the need for a continuous 5mm² of airflow. As it is made from just one component it is economical and easy to install.

The roll-out system makes fitting a breeze as it is supplied in a handy box dispenser with no need for specialist fixing tools. The Manthorpe G1105 Flash Vent is made with a series of nodules incorporated into the design on both sides of the flexible vent roll. This not only provides the required airflow but includes an integral fly screen and maximises support of the lead.

This Manthorpe Flash Vent has been independently wind tunnel tested for weather tightness and can be used over profiled tiles, non profiled tiles and slates without compromising its effectiveness. Two widths can also be joined together to fit any length of lap between the lead and the tiles.

Hi how do you make sure the end of the abutment ventilator is watertight . Do you supply end caps of some sort ?
The abutment vents are self-sealed units that interlock together. There is no need for an end cap even when cut. Simply over-flash with lead or a tile course.
