A moisture penetration preventing manifold protects exterior walls from moisture entry into a wall cavity when wires, cables and pipes must penetrate the wall. The manifold is a solid, waterproof material having a tubular sleeve with a plate at one end sealed to the sleeve. The plate is placed on the exterior of a wall with an upper portion of the plate underneath an exterior moisture barrier sheet, and a lower portion of the plate on an exterior of the same moisture barrier sheet to provide a continuous drainage plane on the exterior. A building service element such as a wire, pipe or the like is passed through the sleeve and the sleeve central passageway is filled with a sealant such as expandable foam to prevent moisture from moving through the passageway.
A manifold providing a passageway for a building service element from one side of a building wall to an opposite side comprising a tubular sleeve, a plate sealingly mounted on the tubular sleeve and positioned at substantially right angles to an axis of the sleeve, the tubular sleeve extending through a building wall to permit passage of a building service element through a central passageway of the tubular sleeve.
For a building wall construction comprising an exterior panel, and a flexible moisture barrier sheet on an exterior side of the exterior panel, the improvement comprising a manifold for passage of a building service element from an exterior of the building wall to an interior of the wall comprising a sleeve made of a moisture proof material, a plate sealingly attached to an exterior of the sleeve, the plate being positioned to the exterior side of the exterior panel, the flexible moisture barrier sheet being slit with an upper portion of the plate between the flexible moisture barrier sheet and the exterior side of the exterior panel, and a lower portion of the plate positioned on an exterior side of the flexible moisture barrier sheet , and the sleeve having an interior passageway of size to permit sealing the passageway around a building element in the passageway of the sleeve with a waterproof filling material.
A method of providing for a water barrier passageway of a building service element through a building wall, the building wall having a first side and a second side, comprising the steps of providing a manifold having a tubular sleeve and a flat plate flange sealing mounted on the exterior of the sleeve, the building wall including a wall panel, and a moisture barrier sheet on an exterior surface of the wall panel, the method including slitting the moisture barrier sheet and installing an upper portion of the flat plate flange between the exterior surface of the wall panel and the moisture barrier sheet, and placing a lower portion of the flat plate flange to an exterior of the moisture barrier sheet, passing a building service element through a passageway formed by the tubular sleeve, and filling the passageway of the tubular sleeve with a sealant surrounding the building service element to prevent moisture from moving through the passageway.
