Field Demonstration of Alternative Wall Insulation Products

The NAHB Research Center conducted a field demonstration to compare the cost and performance of spray-applied cellulose, blow-in-blankets, low-density polyurethane, and fiberglass batts in exterior walls. Four production builders each provided a group of nearly identical homes for the study. Two homes from each builder represented the builder's typical practice. Alternative insulation materials were substituted into the walls of the builder's next three homes. The builders' conventional material (i.e. batts or blown-in loose fill insulation) was applied to the roof/ceiling assemblies. Infiltration and energy savings were estimated and compared to installed costs to calculate simple paybacks.
