With their double headlap, the typical minimum
pitch for clay plain tiles has traditionally been 35° for machine
made products and 40° for hand made. However, in keeping with recent
developments which enable certain plain tiles to now be laid at 30°,
Klober’s Clay Plain Tile Vent has been confirmed as fully watertight
at the lower pitch. Designed in the format of 5 plain tiles, the
vent is virtually invisible in the roof line.
It provides a 9,000mm2 effective vent area and can be used to supply either high or low level roof space ventilation.
