Questions & Answers

Question:

Hi Would this be suitable to connect to a 100mm bathroom extract fan? going through a flat roof? And how would I fix it to the roof to ensure water tightness?

Answer:

This would be suitable for 100mm, you need to dress the roof covering over the flange to ensure a tight seal but the roofer completing the work can normally assist with this.
