One of the other jobs that we have been diligently working on is the hearth for the fireplace, along with the firebox. Instead of using a more traditional firebrick or refractory brick made of ceramic material, we have chosen soapstone which can also be used as firebrick because of its unique composition. Soapstone is a natural material – metamorphic rock – formed millions of years ago under intense heat and pressure. Because it started out in a molten state deep within the earth, and because it has an unusually stable composition, soapstone can comfortably withstand fire and dramatic changes in temperature.
For centuries, soapstone has been known for its ability to retain heat. Other natural stones, such as granite and marble, also hold and radiate heat, but only soapstone has the added benefit of being able to withstand direct flames indefinitely without splitting or cracking. While burning wood is not helping our carbon footprint, the slow release of heat from the soapstone is a more energy conscious decision in terms of warming our apartment as compared to a more traditional refractory firebrick. While there was a marginal up cost to using soapstone, we are also much happier with the aesthetics of it.
Below you can see where the old hearth was located above the brick buried in the floor. ACE placed concrete over the brick and then placed a 1/4″ thick piece of plate steel on the wet concrete. This was then leveled to make the base for the hearth and to prevent heat from the fire from migrating downwards into the floor joists where it could possibly start a fire…
It is important to remember that the design of fireplaces is strictly regulated by the building code, even when refurbishing an existing fireplace or chimney with a new wood burning fireplace. Be sure to consult with a professional before attempting this job on your own.
Above you can see the completed hearth and the flue for the smoke chamber which will sit directly above the damper and the firebox. Prak from ACE did a cosmic job laying the stone for the hearth. Super level and all the joints are aligned. Total pro! Again, can’t say enough about Sonny and ACE. Great job, great price.
