Video: Fiberglass Vs. Cellulose Loose-fill Insulation

It’s a somewhat silly knock-down, drag-out fight using a lot of not-so-silly science and a bit of FIRE!

In this video, Stacey Greenawalt dons five? six? Several personas–AND does an experiment with fire–to illustrate the fundamental differences between blown (or loose-fill) fiberglass and cellulose insulation.

Stacey references a similar experiment by Inspectapedia. Here’s a link to that.

Also, here’s CSPC report on cellulose that includes the fire hazard info:

PLEASE NOTE: We are discussing BLOWN insulation. Blown fiberglass is fireproof. Unfaced fiberglass batts are too. It’s when you add a kraft paper backing to the fiberglass that it is no longer fireproof (however, it’s still more fire resistant than cellulose).
