Kinstone Chapel

Kinstone Chapel

Another group of talented, interesting and wonderful folks attended the Cordwood Workshop at the Kinstone Chapel near Fountain City, Wisconsin on July 13-14, 2013 to continue the building of the chapel’s cordwood walls.  As you may know, this Chapel is being built using the symbols/motifs from the Canticle of Brother Sun and Sister Moon.

Here are a slew of pictures of mixing mud, screening sawdust, building walls, tuck pointing, covering walls, conversing, concentrating, eating and generally having a grand ol’ time.

Mixing a good cordwood mud...chop, chop, chop went the hoe.

John brought his solar telescope so we could see sun spots and his evening telescope so we could view Saturn and the craters on the moon.  Amazing!  Thank you John.

We even had snacks on site!  Here Cook 'Par Excellence' Dorothy receives a hug from instructoress Becky for a delicious piece of Mona's fresh baked bread with Joerg's home harvested honey!  Ummm Good!

This is the bottle and log end wall that will surround the entrance way to the Chapel.  Our two cordwood wood mason's are very pleased with their work (and so are we!)

Covering the walls at day's end is a very important practice to ensure a slow set and cure of the mortar.

Eco-Panels Installed

Eco-Panels came out on Tuesday and Wednesday and installed the S.I.P. roof.  The finished roof system for the Nauhaus Prototype will have an insulation value of about R80 when completed, because the spaces between the 8″ rafters will be packed with cellulose.

Some information about Eco-Panels, from their website:

For a truly superior building envelope Eco-Panels manufactures the only R60 panel on the market today coming in at just 8.5″ in thickness.  This panel, designed specifically for use in arctic regions, is perfect for the passive house or net zero energy designs where most modeling software calls for an R40 wall and R60 roof (of course this will vary based on region).  This roof panel will perform at better than R60 at 20deg F (-7deg C) using LTTP (long term thermal profile) and temperature vs k-factor performance data provided by the foam component manufacturer.

  • 8 1/2″(21.6 cm) = R60+
  • Maximum panel length is 12′-0″ (360 cm) although this can be increased to 16′-0″ for large opportunities
  • Maximum panel width is 4′-0″ (120 cm)
  • The insulation is high-R-value polyurethane foam injected at a density of 2.5 pounds per cubic foot.

Foam Insulation Sprayed

Today, Home Energy Partners came out to spray the closed-cell insulation for the slab and exterior walls.

Advantek sheathing and brick mold are installed first to stop the foam and eventually to support the Hemcrete.

Slab Edge Insulation and Drain

Today the foam insulation and drain were installed at the edges of the stem walls, and the CMU was sealed.

This insulation will serve as a thermal break for the concrete slab.

Mycelium Insulation

Ecovative Design is producing SIPs panels using dehydrated mushroom roots.

We use fungal mycelium, which is basically the roots of mushrooms. The mycelium acts as a resin to bond agricultural byproducts together into a rigid material. We don’t let the mycelium grow long enough to produce mushrooms. That means you never have to worry about spores or allergens.

mycelium

Mycelium is incredible stuff. It builds topsoil. It digests petroleum. It can be used to kill termites and carpenter ants. It can be used to make fuel and cure diseases. Watch Paul Stamets’ TED presentation:

Soy Based Spray Foam

“I bought some cans of [soy based foam] from home depot. I also bought some “Great Stuff” spray foam. I tested them side by side and the Biobased foam failed. It might have been the cold but it dried dry and crumbly. In comparison the Great Stuff dried like hard chewing gum…

Biobased foam crumbled when touched. This could be because it was cold when we installed it. But Great Stuff was installed exactly at the same time in the same environment…

This is very important because the foam is used to fill cracks. Cracks often expand and contract. The Great Stuff has an elasticity to it that the Biobased does not. Also, I forsee the Biobased foam deteriorating and becoming dust over time.”
