Retrofit Insulation: Polyurethane Injection Foam Goes in Without the Walls Coming Down

Another variation of injection foam that is picking up steam in the booming retrofit market is a slow-rise, open-cell polyurethane formula. The hybrid product, whose superior insulating and sound-attenuating qualities give phenolic injection foams a run for their money, has a secure place within the contemporary housing climate in which people are making updates to existing homes rather than purchase new ones.

This line of retrofit SPF is almost identical to its open-cell spray-in counterpart; it has nearly the same physical properties and characteristics, provides the same r-value, meets all the same safety credentials and certifications. The key difference lies in its prolonged reaction time and method of application.
