I have torn down some rotten ceiling and insulation and repaired some holes in the roof of the trailer. I have survived a few wicked rainstorms so I am ready to put ceiling back up. Previously there was the pink fiberglass insulation between the ceiling and the roof.
My question is, should I go back in with the "puffy" fiberglass insulation or can I get by with the insulpink Installation boards?
As I type I pretty much think I should go with the regular insulation as I can tuck it up into the rafters, but wanted to get some other opinions.
I can't say which is best but mine has styrofoam insulation. I think styrofoam panels along with expandable foam to fill in the cracks and spaces would be the best.

Interesting concept. AND, I can get pretty much all the styrofoam I want where I work for free. I will have to cut to size but that free word sure does ring true!

Check the R rating. I was looking at putting different types of insulating blocks on the inside of my garage door. The fiberglass had a higher R value than any of the styrofoam

I installed insulation many, many years ago. At that time, the fiberglass stuff would way outdo any kind of board. Check the R values. I think styrofoam will be way less. And you will have to deal with all the cracks and edges in getting an air tight seal.

Despite what many might think, the Air Pockets in the insulation, are what give you a R-Value.
So, loose "batting" will give you much better insulation than "Pink", or "Blue" styrofoam............for what we want.
Naturally, don't Pack it in, gently push to fill the air space, and trim any excess..............IE, 3" space, but 4" insulation avail............don't Shove it all in, trim off that extra inch, then put up your wall (or ceiling).................it needs the "Space". ...to work.
That is why most all units have " fluffy " insulation in roofs, and sidewalls.

Follow this advice. This is how it should be installed.
