Drill and Fill Insulation for Older Homes in Canada: How Dense-Pack Cellulose Retrofits Work

Most Canadian homes built before 1960 have zero wall insulation, just bare cavities behind plaster and lath. Drill and fill solves that in a single day from the outside, with no interior demolition, by dense-packing the wall cavities with cellulose at 3.5 lb per cubic foot. Russell Smith walks through how the retrofit works, why dense-pack cellulose beats foam and fibreglass for old walls, the typical 15 to 25 percent heating savings, and which provincial rebates in NB, NS, PEI, NL, and BC apply.
