Choosing Blown In Insulation
LESLIE: David in Wyoming is shopping around for some insulation. How can we help you with that?
DAVID: Yes. I’m very interested in making a comparison between two similar products – the pros and cons of each and, of course, the comparative values; one being a water-carried, open-cell, spray-in foam insulation; the other one being a closed-cell, spray-in type of insulation.
TOM: (overlapping voices) OK.
DAVID: The open-cell, I believe, is a vehicle carried by water; the closed-cell is, I believe, carried by some form of urethane.
TOM: Right. Mm-hmm. And where are you thinking about using this insulation, David? Is this in a new house?
DAVID: New home construction, stud-wall cavities and ceiling joist.
TOM: (overlapping voices) Right. OK. Well, David, that’s a very good question. One product that we’ve had a lot of experience with, that is a spray-foam insulation, is Icynene. And it’s a product that’s manufactured out of Canada, distributed in the United States, and they actually have a very green formula that has, as its basis, linseed oil.
And so, I think it’s a very eco-friendly product and then one that does a very good job because it both seals and insulates at the same time. So I would add that to the mix and I think that rather than decide whether it should be open or closed-cell, look for a product that’s got a good reputation and one that’s very eco-friendly. And let the manufacturer worry about what the carrying system is to get it to your walls.
If you look at one that’s got low-VOCs, very eco-friendly, I think you’ll be very happy because, again, it seals and insulates at the same time.
LESLIE: Mm-hmm. And you know what? The website for Icynene is I-c-y-n-e-n-e.com.
