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.

Nauhaus Prototype: Hemcrete®, Eco-Panels®, and Lightning Bug

There’s been a lot of the “sexier” components being put together in the Nauhaus Prototype as of late. Ian Pritchett of Lime Technology flew in from the UK to oversee the installation of the first Tradical® Hemcrete® wall on a home in the US and what he says will be the first Passive Hemcrete® home in the world. Ian and his US partner Mario Machnicki trained Asheville builder extraordinaire Matt Schillig of WNC ProBuilt in Hemcrete® installation.

At about the same time, we’ve had Mark Prudowski of Lightning Bug Electric (more info here) finishing up the electric on the prototype home. Mark and his team, including a graduate from Asheville GO (the awesome non-profit we mentioned in our previous post), fitted the home with “smurf tubing,” ideal for wiring through bio-cretes and other cellulose-based walls. The design will allow for Continue reading Nauhaus Prototype: Hemcrete®, Eco-Panels®, and Lightning Bug
