2" Thick 2300°F Refractory Wool Forge Liner (8#)

1 item left
Hi-Quality 2300° F Refractory Wool for lining forges, fireplaces, pizza ovens, melting furnace, chimneys, kilns, and more.
PLEASE NOTE: All pre-cut lengths are 2 feet wide.

2300° F is the max temp rating, and operating temp rating is closer to 2100° F, which is great for most things..., but not everything.  

Forge metal welding heats can exceed these temperatures, in this application, consider coating the wool with ITC-100 to reflect firebox heat back into the firebox, or using the 2300° wool as a 1' backing layer, with a layer of 2600° wool next to the fire.

Actually I recommend even coating 2600° F wool with ITC 100 too for the increased efficiency, faster heat-up times, and the elimination of the potential long term exposure risk with fibers becoming airborne and inhaled.  It quickly saves more than it costs with efficiency gained, and the peace of mind is of even greater value.

We used to only sell 2600° wool, and the only downside to its exclusive use is cost. In applications outside of forge metal welding's fire exposed surface, many other applications can be well served by the 2300° wool.

NOTE:

  • Wool will shrink and lose mass (appearing to evaporate) when exposed to heats exceeding tolerances over time, with concerns of lost fiber having become airborne in the absence of ITC-100.

TIP:

  • Rigidizer sprayed onto the blanket and fired will stiffen up, making the step of applying an ITC Ceramic Refractory Paint top coat easier, and you are able to prevent compressing the wool during this process, important in maintaining optimal insulation value.
