| I have three of them in-stock in my garage. This is the unfaced side which is usually invisible when installed in a drop ceiling. |

| It cuts easily with a knife. |
Fiberglass batting is generally considered difficult to ignite.
Note that what is often called "fiberglass" is a material that combines glass roving and a flammable resin. That kind of material IS flammable.
I installed the unfaced side closest to the 20 Watt heating mat.
Gulp! I sense we're not getting all of the story! LOL!
ReplyDeleteFiberglass is hard to ignite, but burns furiously when it does. In a suspended ceiling, it's lightweight (less strain on the grid), doesn't absorb moisture like other fibers, and is a good insulator. That, and is easily replaced when necessary.
