Fire Protection Tanks & Exterior Insulation


According to NFPA 22 (16.1), “tanks subject to freezing shall be heated.” Heating and insulating the tank can help prevent tanks from freezing and getting damaged. The temperature of your tank can also be monitored by installing a low-water temperature alarm. Today we’re going to talk a little bit about our fire protection insulation systems and how they can protect your tank:

How do the insulation systems work?

A lot of times you will need to control the temperature of the liquids inside your tank. This can become very costly very quickly, so often times tank owners will install insulation in the tank to more easily regulate the temperature (and save money in the process). There are a few different insulation systems you can get, which we’ll describe below:

Polyisocyanurate foam – This is applied to all tank jackets as it is one of the most efficient insulators out there. It is a good starting point, but most tanks will need more insulation than that.

Mineral Wool – After the foam is laminated to the jacket, composite panels are created and filled with either mineral wool or fiberglass. Mineral wool is the more popular insulation method currently, as it has a higher value (measuring how well the material resists heat) and it is made up of mostly recycled material which means it is better for the environment.

Fiberglass – Fiberglass is the 2nd most common insulation material, and while it has fallen out of favor in comparison to wool, it still provides some benefits you want to think about. Fiberglass costs around 25 to 50 percent less than mineral wool, making it a more cost-effective option. Fiberglass panels also come in more varied shapes and sizes than a mineral wool panel can.

Why You Should Choose Us

If you have no idea what type of insulation your tank would need you are in luck. Our experts can work with you to decide what insulation would work best for your project. We also custom engineer our insulation systems to meet any criteria which may include high wind loads, expansion and contraction, alternating service requirements, extreme hot or cold applications, or custom internal and external attachment designs. No matter what your situation, we will have a solution.
