Product Description

UB41's comprise of a hood on a circular upstand (160mm diameter), a 500x500mm Ubiflex flashing skirt, and a stepped adaptor.

The tortured path through the 4mm louvred grille and internal weathering geometry is designed to maintain a consistent amount of air flow per unit, whilst any water ingress is channelled out of the vent and on to the roof covering.


  • Suitable in most tiled and slated pitched roofs
  • Ease of installation - adaptor is cut off at required diameter and then attached to undertile spigot with a solvent (Ubiflex high tack sealant reommended)
  • Stepped adaptor allows connections to 100mm/110mm/125mm/150mm/160mm diameter ducting
  • Water ingress is channelled out of the vent and on to the roof covering


  • Suitable in most tiled and slated pitched roofs, regardless of make or design
  • The Ubiflex flashing allows fitting into most tiled and slated pitched roofs
  • Can be used for high and low level roof ventilation requirements
  • Unit may also be used to terminate soil and vent pipes where an external pressure test is not required

I used the product on an old roof of Pan tiles to connect to extractor fans in ladies & gents toilets, as the flashing around them could be dressed to any tile etc. There is a terminal for pan tiles but without going to the roof & measuring the tiles I didnt know if it would fit, it could have been for concrete pan tiles & not clay

This roof vent is a good-quality product. It is easy to fit and works well. It blends in well with the concrete tiles on my roof. I have used one of these previously and did not hesitate to order another for this current job.

Roof Vent for fan extraction. Recommended by fan supplier so it must be suitable. Time will tell but product looks good.
