Product description

Enerpaper’s cellulosic insulation system is a revolutionary solution for green construction projects seeking sustainable and high-performance thermal and acoustic insulation. The system utilizes chemically stabilized paper reels made entirely from recycled newsprint, processed on-site using a compact mini-mill. This innovative approach ensures uniform and high-performance insulation, with additional benefits such as flame retardant, anti-mold, and anti-dust properties.

By producing the insulation material from recycled sources and applying it in situ, Enerpaper minimizes the environmental impact associated with traditional insulation methods. The elimination of boron salts and reduced chemical usage further contribute to the eco-friendly nature of the solution. The production and installation process is highly scalable, cost-efficient, and labor-friendly, making it suitable for both new construction and retrofitting projects.

The result is superior insulation that not only reduces material volume but also improves indoor air quality and lowers the carbon footprint of buildings. Enerpaper’s engineering breakthrough combines sustainability, cost-effectiveness, and performance, making it a compelling choice for green construction and energy-efficient buildings.

About the Company

Enerpaper S.r.l. is an Italian cleantech company founded in 2016 and headquartered in Turin. It produces innovative cellulose-based thermal and acoustic insulation made from 100 % recycled paper reels. These reels are chemically treated for flame retardancy, mold and dust resistance, and are flaked on-site using a dedicated blowing machine—resulting in efficient thermal insulation with minimal chemical additives and reduced waste. Enerpaper’s production process leverages existing paper mill infrastructure, enabling significantly lower costs, streamlined logistics, faster installation, and healthier working conditions. Their solution achieves better insulation performance using about half the material compared to conventional products, while lowering CO₂ emissions and improving indoor air quality. Incubated by the Politecnico di Torino’s I3P Innovation Incubator, Enerpaper reflects a strong commitment to circular economy principles, sustainable building materials, and eco‑friendly innovation.
