Located in Asheville, North Carolina, the 3,400 square foot Push House features a mainstream design with some very different systems behind its walls. The home’s use of hempcrete was only the start — for this application, hemp hurds are mixed with lime and water on-site and poured in-between the exterior supporting studs in lifts. It is the core to a breathable wall system — Hemcrete is actually less like concrete and more like infill straw bale, as it is non-structural. The insulating quality is r-2.5 per inch, and it has the unique ability to capture airborne pollutants over time — it absorbs carbon when it is grown and in place. The material’s high thermal mass helps keep a steady interior temperature as well.
