    Abstract

    An unbonded fiberglass loose-fill insulation was selected for this sidewall application study. The insert tube technique is described and the parameters that affect pneumatic application of the product are identified. The initial evaluation was conducted in the laboratory and included density and thermal testing. The laboratory results were then utilized in field studies.

    Ten homes with no sidewall insulation were retrofitted. Thermographic scans of sidewalls before and after retrofit confirmed the predicted reductions in heat loss based on calculation techniques given in the ASHRAE Handbook of Fundamentals. The improvement was further confirmed by comparing utility bills. Typical problems that occur while preparing a house for sidewall retrofit are discussed. The simple payback for typical houses is presented.

    Good correlation is shown between laboratory test results and field performance. Test data indicate that the application procedure used gave an “effective R-value per product claim”.
