Tank Insulation

What we apply

• Closed-cell polyurethane spray foam on the sides and top of the tank
• 2″ thick as standard; 3″ or 4″ available
• Rated R-6.7 per inch: over R-13 at 2″, about R-20 at 3″ and R-27 at 4″
• A white mastic sealant over the foam for UV protection. Mastic stretches as the tank expands and contracts with temperature changes.

When you need it

Insulation is common for chemicals that freeze or crystallize in cold weather, such as concentrated caustic soda, and for liquids that must be held at temperature. Heat tracing is very often chosen with insulation, and heat tracing always requires it.

Insulated tanks

Every insulated tank is listed with its price with 2″ of insulation. On each tank’s page you can choose 2″, 3″ or 4″ and see the price for that thickness:

• Insulated double wall tanks
• Insulated single wall tanks
