Wood-burning stoves have provided heat inside homes and buildings for years, although sheetrock, or drywall, has been in wide use only since World War II. Drywall is a product made from gypsum, a mineral slow to burn.
Local building codes specify the kinds of chimney pipe that need to be used with wood-burning stoves. Most codes require that the stovepipe have a double-wall construction and metal flashing around the structures that the pipes go through to vent outdoors.
A properly installed wood furnace or stove can help people save on gas, oil or electricity. Wood burns hot and in some parts of the United States is readily and inexpensively available. A properly installed chimney pipe is safe going through sheetrock and other building materials.
