In this video, we expose a mocked up wall, one side insulated with
cellulose, the other with fiberglass, to the flame from a 400,000 btu
torch. While both products have a Class A fire rating, their
performance is very different. The cellulose quickly chars and protects
the wall behind it, while the fiberglass melts. Click here....
Humidity and Cellulose
Cellulose Moisture Management
Cellulose is hygroscopic - it can absorb and manage the natural
airborne moisture drives in a structure. Fiberglass is hydrophobic. It
can't absorb and manage moisture. Under the right conditions, this can
allow moisture to concentrate within a building cavity. Click here...
Noise reduction
Cellulose Sound reduction
Cellulose has a very high STC (Sound Transmission Coefficient) rating, and does an excellent job reducing airborne sound. In this video, we show you how cellulose and fiberglass compare in their ability to make your home a quieter, more comfortable place to live.
When cellulose is used in new construction, it requires that the cavities be netted first. In this video, we demonstrate how a wall is netted and filled with dense packed cellulose. The same process is used to retrofit existing homes. Instead of installing a netting, the contractor uses existing empty walls (sheet rock or plaster on one side, plywood and siding on the other side)
