Our insulated double wall polypropylene tanks are double wall tanks with a 2" thick layer of Polyurethane closed cell foam insulation applied to all outer surfaces except for the bottom of the tank. Closed cell foam, as opposed to Open cell foam, is comprised of sealed foam bubbles that do a better job of insulating and do not soak up moisture like a sponge. The layer of insulation on our tanks is sealed with a White mastic coating.

R-Value

The polyurethane closed cell insulation on our tanks has an R-value between 6.0 and 6.5 per inch of thickness. With a 2" layer, the R-value is between 12.0 and 13.0. Since this is a sprayed foam product, the properties can vary slightly from one tank to the next.

Tank Standards

The polyethylene vertical and open top tanks meet standards set by ASTM D 1998. There are no ASTM standards written for other tank shapes or resins.

Heat Tracing

These insulated tanks do not include Heat Tracing. Heat Tracing is the use of specially designed Heat Pads and a digital control box to keep liquids from going below a pre-set temperature. For water storage, this would be to keep the water from freezing. For Sodium Hydroxide or Caustic Soda storage, the maintenance temperature would be at least 65 degrees and possibly as high as 85 degrees.

We can easily add Heat Tracing to any of these tanks. We need a bit more information to properly calculate the right heat pads. Click here to give us the Zip Code where the tank will be installed, the liquid you will be storing, and the maintenanace temperature you need for the liquid.
