A Class A chimney pipe is a type of insulated chimney designed for high-heat appliances like wood-burning stoves, fireplaces, or furnaces. These pipes are engineered to withstand temperatures up to 2100°F (1150°C), providing a safe channel to vent exhaust gases outside your home. They are often required by code for wood stoves or other solid-fuel heating appliances.
Class A chimney pipes typically consist of two layers of steel with a layer of insulation in between. This insulation helps maintain the heat inside the chimney while keeping the exterior cooler.
