Still plugging away at the insulation and the foil taping..
The funny is, it's 97 degrees outside, inside the trailer it's 102, and I'm insulating the trailer.
I know it will help,
with the heat and the cold..
Got all the foam insulation in around the top where the rvlovent fan goes, was on such a roll, I forgot to install the board to mount the fan too.
so had to cut some of the foam back out for the double 3/4" board mount for the fan.
While I was at it, went ahead and cut the hole for the fan. tried it in the hole, it fit, and taped it in temporarily..
No rain for the next 2 days so good there. At least with it open 3 inches it will let the heat out that's been building up inside.
When I'm ready to install the fan, will clean the top really good. Use butyl tape on the flange that sets on the metal roof. Use the metal screws that came with the fan. Tighten but not over tight. then 3 or 4 days tighten a little more. The butyl will have softened up by then and squeeze out a little sealing it really well along the edges.
If there are no dips in the roof around the fan, I will seal around the fan with 100% silicone. If any dips I will seal with Dicor leveling caulk.
