The class is designed to provide auditors and installers with thorough knowledge of these two insulation products which have become very popular in Indiana’s Weatherization Program. Regarding spray foam, we will explore the best applications for “two-part”, alternative packaging and delivery systems, and safe practices. Topics relating to “dense pack” are the details that make dense pack perform better than standard wall insulation, how to recognize and treat “key junctures” that are common in older buildings and introduction to all of the relevant tools and techniques. One day will be spent in the field.
