Hi all,

I would like to install a terminal vent (Ubbink OFT-1F) for my cooker hood onto the roof of my extension, which is built up felt. The vent has a integral plastic flange.

I'm fine with cutting a hole through the roof as required but i was wondering if someone could tell me what i should be doing with the felt...

Thanks
