The "Double Wall Insulated Cap", a device that when used will conserve heat in a dwelling. For use mostly to plug a flue pipe opening situated at the exterior wall of a dwelling. By plugging that particular hole usually situated, leading directly out to a chimney bottom with an insulated double walled cap, the insulated cap stops heat from escaping out the hole in the wall and prevents cold air from entering the dwelling, when the heating unit is not in use. It is also effective during hot summer months, when air conditionners are in use, when used it caps hot air out and cold air in. The "Double Wall Insulated Cap" uniquely because of its double wall nature fits to all standard sized flue openings and also at any angle.
