Fantastic fan flange install

[Pat C]

We installed a fantastic fan/vent about a year ago.Never got around to putting the finishing flange on the inside.I have spacers sent from the Co.and a sized down flange so everything is ready to put up.HOWEVER I am unsure about using screws provided to install this.What have others done.I am positive that any screw used will go through the roof.Thanks...Pat.

My flange went unfinished for a couple of years. As my trailer is painted, as opposed to gelcoat, I decided to add the spacer outside, on top of the roof. Being painted, I can easily hide my mistakes.

Two 3/4 inch plywood cutouts sandwiched together with fibreglass and resin. I then was able to flush mount the flange on the inside. gives that little extra headroom. I could then put screws,from the inside, through my roof directly into the fibreglassed plywood.

I will be posting a video shortly.

I added a wood frame made out of 1 x 2 inch poplar between the "flange" and the ceiling.

Hi Fredrick, How did you attach the wood frame to the ceiling? That is my problem,I am not keen on screwing something to the ceiling. Did you use screws and if so what size? Pat.

Could someone use something like Liquid Nails to glue it?

Hi Fredrick, How did you attach the wood frame to the ceiling?

First, note that I do not have any interior covering. My interior is just paint on the inside of the fiberglass.

I used Gorilla Glue. It needs to have pressure applied while the glue sets. I used a piece of plywood and a 2x4 braced against the floor to press the glued frame against the ceiling for 24 hours.

Glueing sounds good.Think I will try that.Does anyone have a suggestion as to what glue will bond well on the ensolite?Something that is available in Canada.Thanks.

After having my Fantastic Fan installation remain unfinished for a few years I decided to add a spacer on top of the roof in order to keep it flush with the ceiling on the inside.

I fear that a wood spacer would not bond well to the ensolite; it would be too heavy and either come unglued or pull the ensolite away from the fiberglass.

If it were me, I would pull the ensolite back a little bit, and bond the wood directly to the fibreglass. Then I would trim the ensolite to butt snugly against the wood.
