US 6,401,401 B1 · Multi-component flashing systems

Abstract

The invention relates to an improved multi-component flashing system for controlling water and air that intrudes at windows, doors, louvers and other wall penetrations. It accomplishes this through the use of several known commercially available products which are applied to the areas to be protected in a unique manner thus saving time and providing a heretofore unknown measure of protection. The first product is an elastomeric adhesive sealant which readily bonds to most building materials as well as the components of this system. The second product is a clay coated polyethylene film which can be folded, cut and shaped to fit various opening conditions. A third, optional component, is a uniquely designed preformed flexible termination accessory which also readily bonds to the clay coated film material through the use of the elastomeric adhesive sealant. The clay coated film material is readily available in roll form and can readily be hand cut to the dimensions of the particular job. In some instances, the flashing will be completed through the use of the coated polyethylene sheet flashing in combination with the elastomeric rubber adhesive sealant. Optionally, termination accessories may be used in combination with the coated polyethylene sheet flashing material, and the elastomeric adhesive sealant. The termination accessory has been specially designed to allow the same unit to be used in opposite corners of an area to be protected, thus reducing the types of units required on a single job by fifty percent.

Dependent claims

A flashing system for preventing intrusion of water and air at windows, doors and other through wall penetrations comprising:

through wall rough opening means in a building structure comprised of a pair of spaced vertical stud members and a horizontal base member interconnecting said vertical stud members forming a pair of opposing rough opening base corner areas to be protected against water intrusion and an optional exterior sheathing board layer attached to said stud members;
a sheet of clay coated polyethylene sheet flashing material hand cut to the approximate dimensions of said through wall rough opening area to be protected with a rear upstanding portion extending the full width of said through wall rough opening
and secured thereon with a clay coating on at least one side of said coated polyethylene sheet flashing material facing outwardly and secured thereto by attachment means comprising an elastomeric adhesive sealant;
a coating of elastic adhesive sealant applied to the outer surface of said clay coated polyethylene sheet flashing material in said opposing corner where said vertical stud members and said horizontal base member intersect since these are the most likely areas of water intrusion;
and preformed termination accessory means installed in each of said opposing rough opening base corners over said elastomeric adhesive sealant followed by another coating of said elastomeric adhesive sealant whereby said sheet flashing material, said elastomeric adhesive sealant and said preformed termination accessory all readily bond to each other to provide weather resistive protection at the opening in preparation for subsequent installation of a through wall closure member and said installation of the system easily interfaces with other construction materials and techniques to control water and air intrusion.

A flashing system for preventing water and air intrusion at through wall penetrations of a building comprising:

throughwall opening means in a building structure including a sill member, a pair of spaced vertical studs forming jamb members attached to said sill member and a header member attached to upper ends of said stud members forming said throughwall opening;
attachment means comprising an elastomeric adhesive sealant applied to said rough opening members at specified locations;
and
flexible flashing means comprising a plurality of clay coated polyethylene sheet material pieces folded and secured to said rough opening by said attachment means and reinforcing means selectively applied to strength high stress areas;
whereby said rough opening is provided with protection against water and air intrusion for a closure member when inserted in said rough opening.
