New Frameworks is a design/build firm in Essex Junction, Vermont, and one of two extant straw panel producers in the United States. Tyler Westerman spoke with Co-CEO and Director of Vision & Strategy, Ace McArleton, to learn about their move from bales to panels. The scope of their conversation soon grew beyond panels to the future of sustainable construction and ethical labor. The conversation has been edited for length and clarity.
Tyler Westerman: Tell me about the history of how New Frameworks arrived at its straw panel system.
Ace McArleton: In our early years, we would do the nomad natural building thing where we would travel. We had projects in Maine, New York State, Massachusetts. We’d build travel costs into our estimate with our client. Sometimes we’d camp on the land or we’d stay in their house. Many people across many ages and stages of their life might pursue that kind of a lifestyle. In general, for us, it corresponded with [the time] before we had families and homesteads to maintain and things that tied us to [northern Vermont]. It became more and more difficult to travel afar and afield to do site-based installations.
We [became] very rooted in Vermont. We only did projects that were within an hour drive of any of us. Some of them might’ve looked less like a classically natural building project, but we learned a lot doing those and applied a lot of local materials. We got into using wood fiberboard, clay and lime plasters, and found a lot of non-toxic caulks, non-cementitious (lime-based) tile mortars and grouts, [and] ways that we could get our natural building world into more of those typical general contractor, high-performance building projects. Where we are now is wanting to synthesize the two and find a way to make it really easy for people to say yes to bio-based building materials. That’s really the main goal for us: how do we make it easy for people to say yes. What is the quickest way for us to get from all of the complexity and the ideas that people have about [natural building] and to make it really easy.
I would point my fingers not only at Chris [Magwood], but almost only Chris, for getting us into [straw panels] with such fervor and focus. Chris is a great friend, colleague, and comrade. Chris and Jen Feigin, while directing the Endeavour Centre, developed straw panels and the idea of panelization in general and modular building with natural materials in North America. Chris had access to some of NatureBuilt’s [a defunct straw panel manufacturer previously based in Ontario] early development, real basic things, but real helpful things, like: what’s the initial size of space that you’re going to need to really take on a project? That was super helpful. Him sharing that information got us started in earnest building our first panels. We built a prototype in 2018 and then we did our first project in 2019. We also were looking a lot at what ModCell was doing, what EcoCocon was doing, and several other European straw panel manufacturers.
TW: Was there a particular project that required panels? What instigated the first prototypes?
AM: An architect approached us who was building a retirement home for himself and his partner in Massachusetts. We don’t live in Massachusetts. We live in Vermont. We didn’t want to travel to Massachusetts anymore and go stay somewhere. The architect wanted to do a certified Passive House project. We consulted on the design, panelized the wall, and sent one of our high-performance Gryphon doors there. That was our first trial project and it went really well. We loved it, and the builder loved it. On that project we put fiberboard on the exterior and we strapped it so it was ready for siding. The interior we sent [wrapped] with Intello [airtight vapor retarder] and strapping, so they had their interior chase all ready to go and could just apply their interior finishes.
TW: How many projects have been completed at this point with panels?
AM: We have two different kinds of [projects] we’re doing. One of them we call “panel only”, where we’re selling just the panel. They send us their design, we panelize it, and then we ship it to them and they put it in. We have projects where we are the designer and we fabricate panels and we install them, or we don’t install them. Then we have projects where we have created a pre-design. We have this line of pre-designed buildings that are essentially kit buildings that we’re [designing] in-house. We are providing the panels for those as well. Combining all of those, this year we did 12 projects. Last year I think it was slightly less than that, maybe 10. And then the year before that, I think it was six. So we’re somewhere in the range of 20 plus.
TW: When you ship it, does it come with an air sealing barrier already on it?
AM: It depends. We are looking at how we can make it really easy for general contractors or builders or whoever’s gonna be receiving these [panels] to be able to work with them. We’re looking at potentially sending them with some sort of cover, even if it was a temporary cover, just to keep them sealed and safe. Some of them we’ve sent with raw straw. We send them with Intello [air sealing membrane] if that’s the detail, but we have sent them with a clay base coat as well. We do a lime stabilized clay base coat, that’s our go-to. On the exterior, we send it with sheathing, with CDX [plywood].
TW: How long does it take to manufacture the panels required for, say, a 1,000 SF house?
AM: Right now, we think about it in terms of the number of panels, because that’s easier for our shop. In terms of estimating, we use square footage of the walls to estimate the project and to estimate the time. We figure out how many panels. Then it’s about how many are standard panels versus [custom, where] we have to do something atypical to them. Right now our shop is building a project for the Buddhist Retreat Center, a welcome center in Montana. This is a collaboration with an architecture firm called Love | Schack, a firm that knows straw bale very well. Their project is, I think, 48 panels. It’s maybe two and a half weeks for their 48 panels and the size of that project [1,472 SF].
TW: Considering that you’ve been building with bales for a while I want to hear about the particular considerations or advantages that come with panels versus bales.
AM: What I will say is, I would never want to speak [in terms of] forever, but, I don’t know if I will ever build a site[-built], [straw] bale building again. It does sound so dramatic, I know. I’m not even being negative about a site-built straw bale. I’ve done many [bale buildings].I love working with straw. And I can imagine that there’s probably just different moments to apply one versus the other. If you know me and my work, or Jacob [Racusin] and his work, or New Frameworks and our work, [you know] we’re not prescriptive. It’s just not our vibe. What is the specific instance and what are the outcomes that we’re looking for? What are the values that we’re trying to apply? What is the [building system] that makes sense in pursuit of that?
What I will say about getting into panelization is that we have a friendly, warm, bright, dry shop that people love to come to. We can have lunch together. You’re not in a field trying to deal with mud and trying to have a site trailer and trying to sit on buckets. I love construction. I love job sites. Again, I’m in this work for a reason. But in terms of producing an agricultural by-product, high-performance, wall system, it’s nice to have a comfortable, controlled environment to work in.
All the years that I built on site… Is the homeowner, or are we, going to get a tractor trailer to rent for the month that we park in the yard? We pull the bales out and then we’re trying to square them on the lawn. Are we doing it on a tarp because we’re trying to collect the chopped straw to put in the plaster? Or do you bring it in the house? But then you’ve got this giant stack in the middle [of the site]. You’re trying to pull from there to the walls while you’re working. So just on the [basis] of basic spatial availability and ease of working with a big stack of straw bales, it’s really nice to do it in a shop. We saw firsthand how much more nice and tight you could get those walls when you have the benefit of a press or a table or frame that you’re fitting them into. That’s one of the nice things that’s disappeared: we don’t have to square them because the compression, the bottom and top panel, the girts, and [the frame] really take care of squaring for us, and give us the compression that we want to get [for] a nice tight wall. It’s also gotten rid of stuffing, which was the other thing that was just an exhausting, long process. Who doesn’t love mixing up some slip and tossing some light-straw-clay and picking up handfuls of it and making knots? But I’m so glad that I’m not spending days doing that in order to get an airtight, fire-resistant wall, climbing all over scaffolding on the inside and the outside of the wall. The prep work to the frame. The air sealing preparation. The preparation of the bales. The process of [bales] going in the wall and fastening them to whatever framing material. Then we need to prepare it for plaster. We need to shave it. We need to stuff it. All the ways that you would treat the wall prior to applying plaster. I’m grateful you asked me this question, to be perfectly honest, because I have not sat down and really ran through all the things we need to do to build straw bale that now we don’t have to do [with prefabricated panels]. It has simplified a lot of the logistics and labor time [of] building with straw bales.
