Insulate?

An aluminum topper can get both very cold and very hot. Insulation might be a necessity.

The whole deeper thought process was started by the report of  an insulation material with the trade name … EZ-COOL.

This “EZ-COOL” sounded really good.

 A 4’x10′ roll weighs less than 2 lbs. It takes about 2 rolls for a regular cab pickup, 3 for sedans, and 4 for most wagons and vans. That means you will add less than 8 lbs when installing it in the largest vehicle.

Q: How thick is this insulation?
A: This insulation is approximately 3/16″ thick.

Q: What is the R Value?
A: Down = 13 Horizontal = 9.6 Up = 8.1 This is better than 2″ of fiberglass insulation.

That seems to be a great insulation for little space.  More insulation values than Reflectix with the same amount of labor.

Not for me.  I decided that it was much easier and much cheaper to insulate my body rather than the whole back of the truck. I have a wool sweater, two great sleeping bags and a cute Carhartt beanie.
