Greenfiber insulation brings environmental and comfort benefits to Beazer’s Zero Energy Ready Home.

Raising the bar on sustainable building is a goal shared by Beazer Homes, Green Builder Media, and Greenfiber, a leading manufacturer of cellulose insulation.

Insulation can be one of the largest sources of embodied carbon in a home, second only to concrete, according to research by Chris Magwood, director of research at Builders for Climate Action. As required insulation levels are expected to rise to meet higher energy efficiency standards, the carbon impact of an insulation product could potentially become even more critical to a home’s overall carbon footprint.

In 2024, Greenfiber is committed to removing 142,246 tons of CO2 from the atmosphere, which is equivalent to the emissions from over 14.5 million gallons of gas consumed or to the carbon sequestered by 142,000 acres of forest or 369 million trees, says Laura Woodford, vice president of marketing for Greenfiber.

“While other types of insulation may require carbon-intensive processes and material sources such as refined oil and high levels of VOCs, which contribute to global warming, SANCTUARY® by Greenfiber is made with 85% post-consumer paper,” Woodford says. “Greenfiber uses low-energy manufacturing processes and short-haul transportation, which results in insulation with the least-embodied carbon of any other major insulation product.”

Greenfiber’s SANCTUARY Blow-In or Spray-Applied Insulation will be installed at VISION House Las Vegas: Crossing the Rubicon, a project by Beazer Homes and Green Builder Media that includes two model homes at the master planned community of Cadence in Henderson just outside of Las Vegas. These homes and all future Beazer homes will meet the Department of Energy’s Zero Energy Ready Home™ requirements.

“Our biogenic, carbon negative insulation product not only diverts paper from landfills, reducing carbon and methane emissions, but it also locks in or sequesters carbon for the life of the home (up to 75 years), further helping us reduce long-term global warming potential,” Woodford says.

Installing SANCTUARY insulation at the VISION House Las Vegas will help Beazer offset other more carbon intensive materials that must be used to build the home, such as concrete, so that the overall carbon footprint of the homes will be lower.

Greenfiber earned an Environmental Product Declaration (EPD) certification for their SANCTUARY insulation, which is based on a lifecycle assessment that evaluates the environmental effect of a product from the acquisition of natural resources through manufacturing, installation and recycling or disposal.

Comfort, Quiet and Energy Savings

While consumers may be less aware of the sources of embodied carbon in their home, they know all about their utility bills, the comfort of their home and the noise they hear from outside. SANCTUARY can address all those issues.

“Our field testing shows that our insulation provides a 60% reduction in sound power,” Woodford says. “Our insulation can reduce heating and cooling bills by up to 20%.”

In addition, Greenfiber enhances comfort with its ability to help equalize temperatures throughout a home. Homeowners don’t need to worry about cooling a hot upper level on a summer day or using extra heat for a lower level in winter.

Performance and Installation Benefits

Cellulose insulation is not only the most sustainable insulation that is broadly available, but it also delivers superior performance benefits that builders can demand a premium for, Woodford says. 

“SANCTUARY is easy to integrate into existing building packages and plans,” Woodford says. “It’s engineered to fill the tiny joints, crevices and gaps in attics, walls, floors and ceilings, creating a dense barrier capable of reducing air infiltration and mitigating sound.”

Builders can choose to install the all-in-one SANCTUARY insulation with a blow-in or spray-applied or dense-packed application. Greenfiber also helps builders meet new code requirements and apply for tax incentives.

Greenfiber meets the requirements for Energy Star Version 3.1 and meets IECC 2012, along with IECC 2021 for states that require Energy Star Version 3.2 for tax incentives.

The installation process for Greenfiber makes it possible for the installation crew to immediately identify a defect and correct it, Woodford says.

Builders can achieve a Grade 1 Installation on the first try with Greenfiber and reduce air infiltration.

  • General “Grade 1” installation requires that the insulation material uniformly fills each cavity side-to-side and top-to-bottom, without substantial gaps or voids around obstructions (such as blocking or bridging), and is split, installed, and/or fitted tightly around wiring in the cavity.
  • This can be done either by a wall spray or dense-pack and netted application, without the need for caulking or adding additional materials.
  • To meet stringent codes, Greenfiber SANCTUARY Insulation and Greenfiber® FRM Insulation for its proprietary SANCTUARY 2-Hour Firewall completely fills gaps, voids, and hard-to-reach places, reducing unintended airflow, helping builders reach ACH 3 or less the first time, and eliminating customer callbacks.

“Our goal is to bring more peace, quiet, comfort and sustainability to a house while supporting the well-being of those who call it a home,” Woodford says. “By challenging the status quo to build homes that improve health and have a positive impact on our environment, we will advance our industry and ourselves.”
