The Manthorpe interlocking plain tile ventilator is designed for use with small format twin plain tiles. The vent features a unique sliding mechanism to adjust its width to suit the different sizes of tiles available. Thanks to this patented design feature, it is the only vent in the market which suits all three styles of interlocking plain tiles; the Redland DuoPlain, Marley Ashmore and Forticrete Gemini. The curved, in-line profile helps to maintain an unbroken appearance to the roofline at high or low level with a range of colours available to suit varying roof styles. The tortured path through the internal weathering geometry is designed to maintain a constant airflow gap of 6,000mm² whilst channelling any water ingress out of the vent and on to the roof covering below, with the 4mm louvred grill in place to prevent the entry of debris and large nesting insects. When using the vent for mechanical extraction or soil stack / vent pipe termination, a 4" pipe adaptor can be fitted to the vent to connect to one of the GRPA Flexible Pipe range.
In order to use this vent for extraction you also need to purchase the below.
