Item just as described. Fast shipping.

Good product. Make sure to wear a breathing protection while working with this stuff.

I want to use this form material to plug my fireplace. Arrived on time in a medium size box. As I pulled the foam out of the box, lots of particles came out with the foam and landed on my for-arms and my leggings.It hurts my skin like thousand pieces of glass stuck to my skin. I had to take all my clothing for a rinse with soap. I later found a big plastic bag and repackaged the material for return. I am not a professional, but I was wore gloves, mask and face covering to protect myself before I opened the box. Unfortunately, it was not enough. The particles are very harmful to me. I advise the manufacturer should warm customers with a hazard warning label.

Finally , put this product to the test. I am very impressed. Built a kiln for bisque firing clay to cone 04 , 1950 F , firing length about seven hours , forty five minutes, the surface of the steel can I was using measured by infrared thermometer a max of 289 F. No heat stress anywhere on the can. Worked great ! Rugged material , has weight and fiber strength but cuts easy with long razor knife.

Love this. Thick, sturdy, good quality. Worked like a charm for my smelting furnace! Will definitely be buying more.

We didn’t know it was so dense so we returned it.

Worked well, will definitely save us money this year.
