After purchasing Fire Block Sealant and reading this warning in the Hearth Wiki, I'm confused:
Adhesives and Cements for Installing and Servicing Hearth Products
Many of the visitors to Hearth.com have asked about which products to use when considering the medium and high
temperatures that stoves and fireplaces are exposed to. Following are some general guidelines as to product types which fit
specific needs.
Note: Products which are sold as “Fire Block†caulk and foam are NOT to be used in stove and fireplace installation or
service.
I'd like to use it as a sealant for my block off plate, bonding it to the fireplace. The literature states that it is a one component non-combustible draft, smoke and fireblocking sealant, designed to resist high temperatures and smoke passage in non-rated construction. It's fireblocking properties are rated at 750 Degree C, 1380 F. Isn't this better than high temperature silicone? Bonds to concrete, brick, metals, wood, plastic and cable jacketing. What say you?
