"Whenever I need insulation work done on my shows or for my construction company, it’s Insta I call." ~ Bryan Baeumler

What’s better fiberglass or cellulose for upgrading and reinsulating my attic?

Cellulose provides a better effective R-Value, is more dense and tighter thus providing better resistance to air movement making it our preferred choice of insulation when upgrading existing attic insulation. Tightening up your home with cellulose insulation not only reduces energy cost but also reduces flame spread if a fire were to start. (check out “The Big Burn”) Cellulose also has the ability to wick and dry, so if you have a leak in your roof the cellulose will draw out the moisture and dry out as opposed to other fiberous insulations which do not.
