Paul sits down with Mike Haasl and Beau Davidson to talk about about fungal insulation, the Red Cabin, and the Bootcamp.

Paul was asked to lead a workshop on building a hugelkultur bed for someone who wanted one but couldn’t build one.  Eight people showed up, half of which were peeved that physical labour was involved and complained to the manager to get Paul blacklisted.  This sort of thing probably won’t happen with BB20 events.  In the upcoming PDJ, lawn chairs and lemonade with umbrellas will be provided for people that don’t want to, but are asked that they don’t yell “you’re doing it wrong”.  At the end of the day, they’re paying to be there, so if they want to waste it watching clouds, that’s their business.

Bootcamp attracts self-motivated and reliable people with a fair level of “give-a-shit” and “figure-it-out”.  There are quite a few filters in place that keep most people out, such as the no tobacco and pot rule, along with Paul’s particular flavor of permaculture, and finally the name “bootcamp” turns a fair few people off.
All the guests seem to want the Red Cabin thanks to it’s privacy and new RMH.  The mass has gone under the bed to free up a lot of room and it’s smaller overall.  This means that it heats up fast, unlike the old one, and it can only take about a third of the wood at a time as the old one, so over-filling is less of an issue.  Biggest problem with keeping the cabin warm is the overall airtightness of the building – it doesn’t matter how well it’s insulated if air can just come and go as it pleases.

The Fisher Price RMH seems to light easier than the other rockets, probably because that house is well sealed – the warmer air inside is already making the RMH’s chimney work even before it’s lit.  Unless there’s an extraction fan on.

oh, come on, that was the worst cliffhanger ever! I listened to the whole podcast and you didn't even get to the fungal insulation.  I'm calling it 296 to 217 for the fungal insulation.

Did you guys ever figure out the under-cabin insulation/plywood situation for the Red Cabin? Paul, you mentioned using the wood from the mill. Mike shot it down due to spacing between boards. I imagine it's because you have live edges on either side of the board? If so, it'd take more wood, but if you really wanted to avoid the solid wood sheet/plywood you could do a stacked wood board or "shadowbox fence" sort of thing. Kind of like laying bricks.

Here's similar to what I'm talking about:

Instead of having that intentional space between boards as in this Finnish vid, you could attach the boards as close as possible to each other, then put another milled board over that seam to essentially close/cover the gap. If you milled off the live edges on at least the boards attached to the joists, you'd have a tighter fit on the edges of the cabin where the live edge might otherwise make an entrance for your mouse friends. Unless you then added a bit of trim to cover the ends, which would give you less milling, but more cutting/attaching.

Whose rules are you playing by? This tiny ad doesn't respect those rules:
