  • Description & Key Features

    Product Description

    The small format mini castellated tile ventilator is designed to provide a quick and simple solution to the problems of roofspace ventilation and mechanical extraction / soil stack termination through a roof covered with a 15”x9” format tile.

    The in-line profile helps to maintain an unbroken appearance to the roofline at high or low level. Designed to suit the leading tile makes, it is available in a range of colours with a moulded textured finish.

    The tortured path through the internal weathering geometry is designed to maintain a constant airflow gap of 5,000 mm² whilst channelling any water ingress out of the vent and on to the roof covering below, with the 4mm louvred grille in place to prevent the entry of debris and large nesting insects.

    Available in a range of four colours to suit the different designs of concrete 15" x 9" format tiles from the major UK tile manufacturers.

    When using the vent for mechanical extraction or soil stack / vent pipe termination; the 4" diameter outlet on the base will connect directly onto one of the GRPA Flexible Pipe range.

    Nail the vent down into postion by perforating the skins over the pre-formed holes. Clip the vent in place using the tile manufacturers specified clips for the relevant profile.
