SIMOND STORECeramic Fiber Insulation Blanket, 4# Density 2400F, 1" x 12"x 24” Fireproof Insulation for Fireplace, Forge, Furnace, Kiln, Wood Stove, Pizza Oven

i bought this for when I'm sweating copper pipe connections. it looks funky but really works well to keep from burning what is behind what I'm soldering.

Good thick pad and performed well under engine exhaust heat conditions, however be careful not to let engine exhaust blow directly on the fiber as it will tear it apartI wound up putting expanded metal on top of the pad and that helped a little but I would not let engine exhaust blow directly on the fiber because it will still come apart

The fiber withstands the heat as advertised. If this is your first time shopping for this insulation, it’ll be fine for direct heat exposure and insulation. My use case is metal smelting using two layers. It’s a consumable material so it will eventually wear, but I have had a good experience with this brand meeting my needs.

I used my thermal imaging device to see how well it could take heat/distribute it/dissipate it.Applying direct flame to it I noticed the following:1. Didn’t catch on fire! Big deal! I held it over flames for several minutes. Just some black singe marks.2. Camera revealed it spread the heat out while keeping the opposite side way cooler.3. Dissipation of heat was decent while it remained warm for awhile the hottest points cooled down faster and same is true for the opposite side.All in all works well. I line some of my cases for electrical projects with it just in case. It’s a good safety net but shouldn’t be your only safety.

Works

Worked as expected

As advertised, works for intended use.

This was a perfect fit and works great, my stove seems to work much better by giving off more heat.
