The Traveler uses hemp-based insulation for a greener living environment and customers can select between three hemp options: "hemp blanket batt" insulation, precast "hempcrete block" infill, or both.
Hempcrete blocks can maintain interior temperatures, among other uses, and are made of the plant's woody core, a limestone-based binder, and water. They're also biodegradable, lightweight, and have no carbon footprint, according to Coexist.
The hemp blanket batt is made of 92% hemp fiber (the remaining 8% is a binder) and is "superior to all insulations on the market because of its high density and thermal mass properties," according to its maker.
