Small Business in California: Spray Foam Application

Burton & Clark Construction, Inc. is a small business in California that offers spray foam installation services. In this video, they talk about the special applications for spray foam.

Special Applications for Spray Foam Insulation – Part One

The following is the transcript of the video:

What are the special installation types for spray foam that may not be typically obvious?

What is very popular in California, especially in northern California, is wine tanks. All the tanks they store wine in. All of them are sprayed with two inches of spray foam.

Wine tanks. Do you have any pictures?

There is a huge market of it in northern California, and there is a market for it in Southern California.

…these types of things.

Yeah. They get big.

These look to be huge.

Yeah. Like that. We spray the outside of those things.

Right. So the outside wouldn’t be silver like that. It would have a layer… So what would you do exactly? What type of spray foam would you use?

You would first clean it, make sure all the dust is off it. Some might have what material it is. Some might require a primer. And then you actually spray roofing foam on it, because it just comes out a lot smoother which is usually a 2.8 density, 3 point density, and then you do two layers of elastomeric roof coating just like basically a roof application.

So sometimes they could be in a control environment. Presumably, you wouldn’t need to do it if it’s in a controlled environment, or would you do it?

No, no. You typically wouldn’t do it, but they would already have the environment already insulated. But this reminds me of though, is the building that this is in, these are typically called pole barns. The reason being is that they’re usually made out of metal. Metal siding and the wind picks up, it’s very loud and rattley. The pole structures they don’t have any installation in there and…

First unexpected applications for spray foam would be wine tanks. Presumably this would be a manufacturing facility in a winery. They make wine in containers like these do they?

Yes. Temecula’s in southern California, that’s about an hour and a half away from me. There is a lot of wineries out there.

I just wouldn’t have visualized the production of wine in big tanks like that. It’s just not intuitive. Well there’s an unusual application. That’s a good one. What else?

Agriculture. Like for example in Idaho. It’s really popular you know that they use pole bars are just screwed together with sheet metal and steel, and sometimes wood. A lot of the farming communities would get awfully windy and they just are loud and rattley. And this would tighten up all the sheet metal, sidings, and roofing. For a nice and quiet and comfortable inside.

It blocks all the gaps and just strengthens the building overall structurally because it forms kind of solid coating.

Exactly. Yeah.

On these cold climate areas in California, horse farms. Where they don’t want the horses freezing out there.

So we’ve got wine tanks, whole barns, and horse barns.

And a lot of these barns, they put in areas for the employees. They’ll attach a little office to them. They need to be insulated as well.

So I imagine a big area. I mean these are just basically like big hangers aren’t they? So if they need to become controlled, I imagine they’re going to be very difficult to because this is such a big open area. The way they’re constructed, I imagine they must be very difficult and very expensive to maintain a specific climate in them.

As long as they do spray foam it wouldn’t be difficult. It seals everything up and all they need is two inches.

Is there a way to define the insulation value that would be achieved in an installation like this?

You would get the 6.5 or 7 R value per inch. 2 inches that would give you 14. So there’s your R value.

You then give them an equivalent of an R14 insulation. Is that what you are saying?

Yes.

So it doesn’t sound like a lot.

It’s fact to the whole thing about spray foam is the air sealing. If you the minimum of two inches in there, the heat or the cold isn’t going to pass that. You have that air barrier in 2 inches closed-cell foam. The R value really isn’t relevant. So it’s still not going to penetrate it, because it has an air barrier. It’s sealed tight,

The reality then you’re saying is that although it’s theoretically an R14, the actual practical benefit of the insulation will be much greater than that.

Yes. We’re back to the performance than prescriptive. Prescriptive it’s an R14. The performance is much greater than that because it has air sealing. An air barrier in it.
