GreenFiber Partners To Help Build Innovative New 'Passive House'

Revolutionary Building Science Technique Designed To Minimize Residential Energy Bills

          GreenFiber, manufacturer of GreenFiber natural fiber blow-in insulation, has partnered with a leading green home builder to provide materials for an innovative green building process that maximizes energy efficiency via unprecedented insulation properties.
          The concept of a passive house, which performs much like a breathable ThermosTM, providing super-insulated properties that keep conditioned air separated from outside air without sacrificing air quality, has been popular in Europe and is quickly gaining traction in the United States. 
          GreenFiber partnered with Bilyeu Homes to provide natural fiber insulation product made of 85 percent recycled content in the walls, ceilings and floors for the construction of the first passive house in Oregon.
          “The concepts and engineering principles behind passive houses completely align with our core values of sustainability and increasing energy efficiency,” said Dennis Barrineau, president of GreenFiber LLC. “We encourage all efforts to make homes more efficient and as comfortable as possible, while minimizing environmental impact.”
          Passive houses are designed to minimize the use of heating and cooling systems, resulting in extremely low energy bills. Ventilation systems help to circulate air within the home, which does not have a furnace.
          A significant amount of planning and computer modeling is necessary before construction on passive homes can begin. The directional orientation of the house, the total window area as well as climactic data is used to maximize efficiency while minimizing energy draw for heating and cooling.
          Insulation is a critical component of home energy efficiency and helps homeowners reduce energy costs by keeping homes cool in the summer and warm in the winter. Adding insulation is an easy project for any homeowner and, combined with other weatherization steps, can cut heating and cooling costs up to 20 percent.

About GreenFiber
          GreenFiber is committed to the environment; it begins by diverting paper materials from landfills for its natural fiber insulation to a manufacturing process that requires ten times less energy than other types of insulation; it continues through local distribution models that help reduce greenhouse gas emissions; and it ultimately delivers value to homeowners with a natural fiber insulation product that provides increased energy savings.
          Additionally, GreenFiber keeps 350,000 tons of paper out of landfills each year through recycling and Community Paper Recycling Programs. Refuse efficiency experts state that paper products account for 34 percent of landfill space -- enough office and writing paper each year to build a wall 12 feet high from Los Angeles to New York City. 
          Established in 2000 and headquartered in Charlotte, N.C., GreenFiber is the largest manufacturer of natural fiber insulation, fire and sound products and the only cellulose manufacturer to receive Scientific Certification Systems (SCS) certification for their natural fiber insulation product manufactured from 85 percent recycled content – 55 percent post-consumer and 30 percent pre-consumer, certificate number SCS-MC-02055. With manufacturing plants located throughout the United States that use local distribution models and require less transportation, GreenFiber products are sold to building supply retailers in the U.S. and Canada.
