WE AIM TO REINVENT CONSTRUCTION INDUSTRY BY INTRODUCING HEMP - IN BUILDING CODES, BUILDINGS, INTERIORS AND MINDS
COEXIST is located on Maiden Creek Farmette in Eastern PA, a 9-acre experimental farm, where we grow different fiber hemp varieties
We grow hemp to make healthy building materials, remediate our soil and improve air.
We host workshops, maker spaces, and events and we partner with universities to facilitate innovations in hemp space
We are passionate about healthy materials and we work hard to spread the word
We work with
We are retrofitting our office with hempcrete, where we are testing a new product we have developed.
We are building a private residence, designed with petroleum-free products, with hempcrete as the main insulator. We will be using hemp grown at the farm.
We will open our doors for a retreat focused on wellness in 2020
We built this hempcrete prototype on wheels to test for durability
After 3000 miles, rain, shine and hail, it still looks brand new
Our team at COEXIST has teamed up with Americhanvre to build this Hemp House On Wheels (Hemp HOW) to showcase the applications of hemp and its adaptability to modern design and pressing sustainability issues; it was designed and built without petroleum- based products.
The walls of Hemp HOW are constructed of hempcrete, or hemplime, - a non-structural bio-composite insulation material that is cast in place around traditional wood framing. It is comprised of hemp hurds (the woody inner core of the hemp stalk), lime-based binder, and water. These simple materials come together to form a product that is mold, mildew, rot, pest and fire resistant. Hempcrete is typically finished, as it has been here, with a three coat, traditional lime based plaster system on the inside and out. This finish allows the hempcrete to “breathe”, passing water vapor freely through the wall system as the lime interacts with varying humidity levels. It is due to this action that hempcrete is able to regulate humidity in a built environment, and why it is touted as a dynamic thermal and acoustic insulation. This system replaces the siding, house wrap, plywood sheathing, insulation and drywall in traditional American home construction. It is hempcrete’s compatibility with other materials and its versatility and performance that set it apart from other well known sustainable building methods.
Our floor has been sealed with Hempsheild, a hemp-oil based natural sealer for wood floors and decking.
The acoustical ceiling tile is made of hemp hurds and mushroom mycelium.
