The FM400 MASS high-end woodburning fireplace is the smallest of the Valcourt line of MASS soapstone masonry wood fireplaces, but still delivers a stunning architectural statement and soothing warmth to you and your loved ones! The soapstone surround will retain and distribute heat for a longer period of time; this is known as thermal mass, and allows the heat from your FM400 MASS to be distributed evenly for several hours after the fire has burned out.
