We are looking at alternatives to leaving windows open for swamp cooler exh aust.
I found up-dux but 70-bucks for 10-bucks worth of simple parts does not cut it when we need two of them.
I have ordered two metal registers and thinking of cutting holes in the cei ling.
Using some fly screen between the register and the ceiling to keep the spid ers and bugs out and we should have an OK exhaust. Yes? No?
I can't see the need for the flap on the up-dux, so here's the question.
Do I need a flap?
If there is a compelling reason I can make some vent boxes with flaps to go into the ceiling, however, I am thinking that just the register then some magnetic plastic sheet to cover the register in Winter would work just as w ell. All for under 20-bucks for two vents and covers.
I can spare the 2-minutes of my time twice a year to install/remove magneti c flaps.
Helpful thoughts?
