The tortured path through the 4mm louvred grille and internal weathering geometry is designed to maintain a 10,000 mm² of airflow whilst channelling any water ingress out of the vent and on to the roof covering.

  • Integral side lock clip to ensure secure fit
  • Suitable for use down to a 20˚ roof pitch
  • Profiles suit all top tile manufacturers
  • Fully independently wind tunnel tested
  • Base outlet feeds directly into roof space
  • Vent size - 418mm x 328mm
  • Free vent area - 10,000mm2
  • Minimum roof pitch - 20 degree
  • Maximum head lap - 100mm

This roof tile vent will suit Double roman Type Roof Tiles.

If you need to connect this vent to mechanical extraction, you will require a an adaptor to convert the rectangular vent entrance on the rear to a circular shape in order to connect to a flexible pipe. Adaptor and Flexi are not included and sold separately.

The Manthorpe range of in-line tile ventilators can also be used as outlet terminals for extraction fans and soil pipe ventilation when used in conjunction with a Manthorpe GTV-AD Flexi Pipe Adaptor and one of the range of GRPA Flexible Pipes.

Product as expected, delivered on time and for a fair price.

I purchased some double roman vent tiles from Southern Roofing Supplies. I had used the product before, so knew what to expect. They were delivered on the day promised, damage free. The price was also considerably cheaper than I was quoted at local merchants, and also elsewhere online. Thank you very much for an efficient experience.
