Drury Brick Core

Masonry Heater Cores

We are the only makers of prefabricated masonry heating components and kits in Vermont. We manufacture masonry stove cores and we are located on Fuller Road in Newbury. Our cores are modeled after a centuries-old heat-storing radiant fireplace design from Finland.

RW Refractory Products are designed for high efficiency, performance, safety, easy installation, and design flexibility. The firebox walls and floors in our heaters are replaceable. We use a Refractory Castable that is rated to 2,400 Degrees Fahrenheit and apply the strictest of standards to our casting process.
