We are thrilled at the success and completion of our first Foam-Free, (near) Net Zero, Passive House in Western Maryland. The home is currently in the final stages of testing and certification and interior finishing. It has been an educational process with material usage, system selection and install, air sealing and insulation, window install and team collaboration.
The views and placement of the house are extraordinary and achieve the homeowner’s goal of a comfortable, accessible, high performance home designed to view the meadow, marsh and forest.

We are helping to realize a sculptor’s design of the Honeycomb House. The project is designed to meet Passive House Standards, be Net Zero Ready and will be completely FOAM-FREE. It is a pleasure and a challenge to be part of this creative venture with Michael Hindle of Passive to Positive and Daniel Gantebein, sculptor!
We are thrilled that this project is now under construction. The owner is serving as general contractor and has overseen the successful initial pour of the basement wall!
As well as the install of our foam-free foundation using perlite under the slab.
The StegoWrap vapor barrier was used and the slab was poured.
Given that this was our foundation plan, I’d say so far, so good!

Upon the arrival of the Roxul mineral wool insulation for sub slab, the contractor relaid the Stego vapor barrier (taped to edges at perimeter). This delay actually may have been a good thing, as the mineral wool was protected from the elements and heavy foot traffic and slab was able to be immediately poured.
The framing of the second floor and roof are nearing completion. We are using 2×6 structural walls with 3/4″ plywood sheathing, all edges and corners taped and sealed. The headers above each opening are two TJIs with Roxul mineral wool sandwiched between them – we have insulated headers! The lead carpenter did not find it to be time consuming or of any issue, but rather thought it was pretty cool and a no-brainer.
The fireplace is a Rumford fireplace, the most efficient design in providing warmth to a space.

The construction for the addition and renovation to our Gunpowder project is moving along quickly. Because the under slab Roxul mineral wool was a little difficult to source and had a longer lead time, our contractor got creative and “pre-installed” the StegoWrap vapor barrier to wrap under the sill plate. We will go back and cut out the barrier to install slab insulation, tape back in the vapor barrier and pour the slab.
Framing is 2×6 walls with 3/4″ plywood sheathing, fully taped to provide our primary air barrier. We are then installing 1-1/2″ of Roxul mineral wool, Tyvek and then furring strips. This has been a terrific learning experience as we work with the contractor and project lead to find economical, smart ways to create a foam-free, well-sealed healthy envelope.

We are so excited to be breaking ground on this project. It has been a long time in the making and through perseverance and the dedication of the owner, we are moving forward! We have really enjoyed working on this project and look forward to seeing it through construction. Hayes Construction is the contractor and will be working closely with us to create this custom addition and renovation. We are so excited that this will be our second FOAM-FREE project!

The slab pour was a successful event!
1. Use slumps for leveling rather than puncturing your vapor barrier with pins.
2. Hold your hose up off the vapor barrier.
3. Make sure Michael has plenty of coffee if you’re going to make him get up that early.
