| Armstrong fiberglass drop-ceiling panel, 24" x 48" x 5/8", Model Number: 404B |

| 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.
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.
ReplyDeleteOwens Corning invented the glass strand weave we know as fiberglass. O-C trademark name for the stuff was fiberglas (one S).
ReplyDeleteMuch like the Q tip cotton swab, the name became so ubiquitous that they lost the trademark.
More useless trivia for fun and games.
To correct the potential fire hazard I would encapsulate with a non flamm material. Thereby keeping the R value.
ReplyDeleteMaybe tin sheet on battens to create air gap.
DeleteWhen building I tend to also consider future use not conforming to current intended use.
Um, I mean furring strips
