| 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.
ReplyDeleteI work real hard to keep similar contraptions outside and away from the main house. Flammable stuff gets the separation treatment. Tougher in your area, but a small shelter 10 feet from the house might be possible? Corrugated tin on 4 x 4's is my favorite skin - if necessary I glue some insulation on the inside.
