"Up here In Canada Fibreglass wins hands down for heat loss! Check back 5, 10 & 20 years later on your Cellulous blown attic spaces, in all our inspections the Cellulous had settled 300-400% in all attics, good grief in most cases we could…"

Blown Cellulose VS Blown Fiberglas in the Attic

As a rater and insulation contractor I personally respect the overall insulation properties of blown cellulose a lot more than blown fiberglass. I have taken numerous infrared images in attics with the same R-values, both products cellulose and fiberglass. I find time and time again poor performance of blown fiberglass.
