Urethane Foam Insulation Demonstration │Central Boiler

centralboiler.com
For over 30 years a hallmark of Central Boiler has been spray-on urethane foam insulation. It’s waterproof, airtight, keeps the heat in the water jacket and delivers more heat to your house, even in the most extreme environment like up here in northern Minnesota.
This kind of insulation is high tech and takes specialized equipment with specialized applicators, training, not to mention talent.
The foam components are stored in a special temperature controlled environment. Urethane foam is comprised of 2 components held in these massive semi-tanker-sized vessels. Component A, Component B.
During the application process when the 2 chemicals are mixed, it results in an exothermic reaction which causes the blowing agent to boil. This results in the foam’s expansion.
Over the years urethane foam insulation has been used in a lot of products; water heaters, refrigerators, motorhomes, it was even used by NASA on the Saturn 5 rocket, which got us to the moon.
Here is a water jacket after it’s been insulated. This closed-cell space-age material is not only water proof and air tight, but it also molds to the contours of the furnace, allowing for an even more compact unit.
Insulation needs to do 2 things. It not only needs to insulate, it also needs to seal. With urethane foam insulation it seals very well. No gaps, no air flow, nowhere for the heat to bleed off.
Now we’ve been expounding on the virtues of urethane foam insulation and you’re probably wondering… if it’s so great, why would anyone use anything else?
A common alternative is fiberglass bat insulation. There’s a number of issues with fiberglass batt insulation. There’s an old saying in the outdoor furnace industry, batts and gaps.
Gaps are not good. Over time, fiberglass batt insulation settles exposing areas to the water jacket where you have extreme heat loss. This is very inefficient.
Moisture is a major issue with fiberglass insulation. Let me demonstrate.
Imagine a driving rain, pushing underneath the rafters of the furnace, soaking the fiberglass batt insulation. Is this going to dry out? No, it’s going to trap the moisture. It’s actually going to cause additional settling and over time it’s going to trap the moisture against the water jacket causing corrosion.
Versus our top of the line spray-on urethane foam insulation. Look at this, it’s water proof, in fact, it even floats. It’s the best stuff out there. Water proof, air tight.
So the question is why would anybody use anything other than urethane foam insulation? Well, because it’s cheap.
For over 30 years Central Boiler has invested the time, equipment, training and resources to use this type of insulation and it’s been well worth it. Nothing else matches it, nothing even comes close.
In fact, if it wasn’t for the significant investment involved with urethane foam insulation, everybody would use it.
Make sure you insist on a Central Boiler outdoor furnace with urethane foam insulation. Accept no substitutes.

Isnt what you are using polyurethane not urethane?

What happens when you develop a leak in your water jacket? You will never know until your jacket is saturated between boiler and insulation’s, rotting the metal.on your jacket.

Keep your inhibitor levels where they should be and you won’t need to worry about it.
The stainless steel water jackets last a lifetime when properly treated water is used. Planning for a leak should not be a factor in choosing the insulation to use.
