No Reflectix. No Fiberglass, either.

For our full monty, we are departing from standard here. We ordered an automotive insulation product called EZ Cool.

A student did a senior project and it required him to test a number of insulations and his very scientific looking results are here: http://www.lobucrod.com/Sr%20Project%20Report1.htm

Additionally, As i further investigated Reflectix I found that it isn't actually an insulation, but a radiant barrier. reflectix on its own only provides an R value of 1. the insulating properties come from the air space between layers; with a manufacturer recommended minimum of 3/4". This is a really great article that probably warrants its own thread:
http://www.energyvanguard.com/blog-b...diant-Barriers

I am going to use one layer of this ezcool which reports R values of:

Down = 13
Horizontal = 9.6
Up = 8.1

Which ends up being cheaper than 2 layers of reflectix. I AM still going to put spacers behind it. also EZ cool offers a discount for rolls of 3+ and will do better on shipping if the actual cost is lower.

I couldn't find any thread of other AIRSTREAMers using ezcool, but it does seeom that other vintage moho folks use it. Anyone with experience with this insulation? Thoughts on product or install?

It's just polyethylene foam sandwiched between two layers of heavy aluminum foil, nothing special.

It's just a low-budget version of Prodex, using a single layer of low-density polyethylene foam for the core instead of Prodex's three-layer laminate of high- and low-density polyethylene foam.

I say "low-budget version" but I don't really have pricing data for comparison purposes. It may not be all that much cheaper, for all I know.

I got a quote and it's not low budget, gulp! I've asked for a sample to take a look at.

Hello, Birdie Momma,

We found your posting about replacing insulation with EZ Cool. We are rewiring and replacing the insulation in our 1964 Overlander and have been researching insulation suggestions. Since yours appears to have been in place a couple of years now, how do you feel about your choice of insulation? Has it been effective?
