Insulating gas furnace exhaust pipe.

Insulating the walls and ceiling in a furnace room can reduce heating costs and make the furnace more energy efficient. Other aspects of high efficiency furnace venting. How to insulate a metal flue pipe. The plastic gas furnace intake pipe can be insulated but any insulation strategy must include a vapour barrier on the outside.

How to insulate a furnace room. The pvc pipes are used for air intake exhaust gas and to remove the corrosive condensation resulting from the combustion process. Traditional gas fired forced air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes or chimneys. This high efficiency venting system must be installed when you install the new furnace.

In contrast modern high efficiency condensing furnaces exhaust much cooler gasses and need only plastic pipe materials such as pvc cpvc or abs for their exhaust vents some high efficiency furnaces also include a plastic pipe for intake area and all types. Without this indoor air will permeate the insulation and condense internally against the pipe. To insulate your pipes follow these rules.
