How do Forticrete SL8 Tile Vents Work?

You can see how our Forticrete SL8 Vent Tile Vent works in the image to the left (or above if you're on mobile).

Air flows through the vent via the underbase unit and grille.

Rain that enters the vent will flow out through the bottom via water channels, onto the roof tiles below.

The pipe adaptor makes an easy connection point for your bathroom extractor fan or soil vent pipe.
