Steve Thomas: Today on Renovation Nation, turning one hundred year old multi family homes into eco-friendly condos. Now this a tool I don't know. I don't have a need for it, but that doesn't mean that I shouldn't own one. Then spray on foam insulation with no harmful chemicals whatsoever. Can you eat it? Marc Rinaldi: You can eat it. It's salty and gritty. Steve Thomas: It is salty and later, green roofs that cool down Chicago's buildings starting with City Mall. Female Speaker: It was actually 74 degrees here, it was 152 on the black tar side. Steve Thomas: Our nation has a challenge, how do we renovate our homes in a way that's in sync with the planet? I am Steve Thomas and together we'll find the answers on Renovation Nation. Sean's next goal is to conserve energy by installing insulation throughout the house. Contractor Sean Jeffords has turned this old mill workers house into two condos designed to conserve natural resources. He is installing a rainwater collection system to save water, and he is about to put in a high performance insulation product to save energy. Since he has just began installing the insulation, most of his walls are still bare. Here you can see the old framing. Sean Jeffords: That's right. Wow! Steve Thomas: Look at this. Sean Jeffords: Yeah, there is some mystery here. Steve Thomas: Still the bark on the rafters there. Sean Jeffords: That's it. I try to keep as much of the design down as possible and maximize that wood. Steve Thomas: All build them, like they're used to, that's a good thing. Sean Jeffords: Grab these, all get up. Steve Thomas: Well, these were never designed to be fancy houses, they were down and dirty workers house, that's it. When Sean bought the house, there was no insulation in it at all. So all the heat that was created quickly escaped through the walls. But all that's changing now. Insulation you are using, which is still wet, what is this stuff? Sean Jeffords: This here Steve is a product that's called aircrete. They call it aircrete because it's cement based foam. Steve Thomas: What's in it exactly? Sean Jeffords: Well, they have got a -- Steve Thomas: Is it a polyurethane foam? Sean Jeffords: It's not polyurethane foam, there is no petroleum, it is a cement foam air mixture, and Mark can probably give us the low down on all the different components a lot better. Steve Thomas: So Marc is the guy who is going to be spraying foam like that? Sean Jeffords: That's right. Steve Thomas: That's one of our projects? Sean Jeffords: That's one of our projects today. Steve Thomas: Cool! Marc is outside with his crew getting the cement foam ready. Marc Rinaldi: Hi Steve, how are you? Steve Thomas: Good. How do you get cement to turn into foam? Marc Rinaldi: What we do is we make air bubbles and then we wrap them with cement. So we run an agent, an expanding agent and when it comes out it's full of bubbles and then the cement comes in through an orifice here which sprays over the bubbles. Steve Thomas: So it's not petroleum based. Marc Rinaldi: Non-petroleum, no. Steve Thomas: It's got no petrochemicals or anything else? Marc Rinaldi: Nothing, no harmful chemicals whatsoever. Steve Thomas: Can you eat it? Marc Rinaldi: You can eat it. It's salty and gritty and it doesn't taste good, but you can eat it. Steve Thomas: Have you eaten it? Marc Rinaldi: Yes, I have Steve Thomas: Your own? Marc Rinaldi: Yes, I have. I have. Steve Thomas: You want to eat some more? Marc Rinaldi: A little bit for you, alright? Steve Thomas: Alright! Is that your sales pitch? Marc Rinaldi: No. I don't need it all time, I really don't, because it's really salty. Steve Thomas: Can I eat it? Marc Rinaldi: You can, if you want. Steve Thomas: It's disgusting. It is salty. That must be the cement Marc Rinaldi: Probably the calcium chloride. Steve Thomas: What? Marc Rinaldi: Calcium Chloride. Steve Thomas: So the foam is not good for eating, but how about shaving? Marc Rinaldi: Fortunately this product makes an exce
