So if only 1 time 90 degree bend is still ok? Bought ems9020 already, and i thought want to sorok the exhaust pipe in the plaster ceiling (10ft ceiling). But later found out cannot do that, because the house got 1&half ft beam at ceiling. So the exhaust pipe will need to bend lower and sorok in the cabinet instead. Should be ok right all sifus?

Dear sifus, my house is under strata act, so cannot do much. I have EMS9020, want to build a window at the yard (allowed by developer) and extend my ducting to the outside of the window. Refer plan below:



My plan is to make a hole on the fixed window (1ft fixed, 3ft can open), and stick the ducting to it. So every smoke or smell will be pushed outside. The thing is, my contractor said can, but after the silicon between the ducting and window glass gets hard (the weather etc), in the future each time i switch on the hood, there will be loud noise (friction between ducting and window glass). I cant build a concrete for the ducting since my house is under strata. Any suggestion?
