Fiberglass roll insulation

[seahorse]

Why isn't fiberglass roll insulation (with vapor barrier) used in teardrop construction, for the roof????

I think it is too much fuss for what it's worth. When you moosh it down, it looses the R-value and if it gets wet................. cripes!! That stuff is like a sponge, will never dry out and ruin your rig.

Now, in saying that, I did use a small amount of that stuff in my TTT but only in the front under the floor by my head. It was a PITA and I hate that stuff !!!

Just go with the pink foam or Reflectix foil insulation............ at least you can cut that stuff on the living room floor.

Sometimes it is. Problem is finding the stuff in 1" to 1-1/2" thickness. Like Jeff said, when you moosh it down, you loose the R-value.

I use the fiberglass water-heater blanket material in my Galley Lids ... works great with my construction methods, and is about 1-1/2" thick ... could work on the rest of the teardrop's top, too, but I like the foam-board better.

CHEERS!

Thanks guys, I will use the foam board for the flat parts......But roll for the tight curves. The saw catches in the foamboard (when kurfing).......scares the hell out of me........Grant, thanks for the quick shipping (hinge).

Seahorse, Have you looked into the white foam board? It is more flexible than the pink stuff. I used the pink on the flat sections and the white on the curved. I just used a razor knife to cut a couple of 'V' groves and it made the 19* radius on my trailer just fine.

I used the 3/4" white stuff every where and only touched it with a razor knife to trim it. I also put the foil outward. Think about it.

Mine did not have foil on it. Just a blue film on one side.

I used the same stuff, had some blue plastic on one side and white on the other. It is really "Bendy" so you don't have to kerf it.

I'll look for the "white stuff"........A razor is alot easier on the hand than a saw blade........ thank you!

Anybody try foil faced duct board ??? foil gives it a radiant barrier too ...

I ripped and curfed mine on the table saw and cut the foam to the correct bevels when going around the curves. I also used a dado blade to cut for "wire channels"... worked great with the hard pink stuff.

The rigid insulation I used on the side walls were a foil faced.
