Sound-deadening with Sprayfoam: Adding unexpected value with SPF


Insulating walls with low-pressure sprayed polyurethane foam (SPF) is a common practice among builders and architects for various reasons—such as increased energy efficiency, structural support, and overall comfort. One of the ways SPF can increase the comfort of a structure is through the material’s sound-deadening properties, which contractors can employ to bring additional value to a project.

The Benefits of SPF in Insulation Applications

NCFI Polyurethanes - 1

by Rick Duncan, PhD, PE

A wide range of polyurethane foam products is available in various densities and open-cell content, each exhibiting different performance characteristics such as application temperature, moisture resistance and R-value, and compressive strength. While a previous article in The Construction Specifier examined the basics of Sprayed polyurethane foam (SPF), this feature examines how foam selection affects installation characteristics, including the maximum lift thickness per pass and allowable substrate temperatures that affect final product performance.

R-values: Controversy and performance values (cont’d)


The first article in this two-part series lays the groundwork for this discussion on R-values and their use as a metric for thermal insulation performance. Now, in this second part, the author examines the real-world use of it as a gauge for ensuring insulation products function as intended.1

When it was created, R-value was really the only useful tool in evaluating the effectiveness of the available building insulations, among …
