Abstract
A moulded, substantially rigid flashing is provided for use in lining transition surfaces in construction. The flashing has a back panel, a base panel and a skirt depending from the base panel.
Description
2 1 ~ 6 1 f~j f.~
Field of the Invention The present invention relates to the field of construction products. In particular, the present invention provides a moulded flashing for brickwork and the like.
Baok~L~I.d of the Invention Flashing is used in construction to provide a moisture collection surface at planes of transition from one building material to the next on the exterior of the building. For lo instance, if a window sill is being installed in a wooden frame, flashing will be provided under the window sill. This will prevent water from leaking under the sill into the wall.
Similarly, flashing is provided under and behind an exterior wall substrate. An example of such a use of flashing is the installation of a flashing layer, usually of sheet metal, beneath and behind the lowermost course of bricks in an exterior brick wall.
Flashing usually is made from sheet metal, bent as required either on-site or in a shop. Lengths of metal are joined together in the field by the application of sealant material, such as silicone ~nlking between overlapping sheets.
It will be understood, then, that flashing of this traditional sort is quite sensitive to folding, bending and creasing prior "~ 6 0 to installation, and is therefore subject to excessive wastage.
Moreover, because each piece of flashing must be bent individually, it is fairly expensive.
It has been proposed, for instance in U.S. Patent No.

It will be understood, then, that flashing of this traditional sort is quite sensitive to folding, bending and creasing prior "~ 6 0 to installation, and is therefore subject to excessive wastage.
Moreover, because each piece of flashing must be bent individually, it is fairly expensive.
It has been proposed, for instance in U.S. Patent No.
3,442,055 (Posey) to use a partially flexible plastic strip as a flashing product. This product offers some advantages over sheet metal, but is imprecise to install because of its flexible nature, and it is subject to tearing.
Another patent, U.S. Patent No. 4,700,512 discloses a more rigid plastic flashing product, but only for use in corner applications.
There exists, therefore, a need for an easy to install, fairly stiff and resilient flashing for use especially with brickwork.
In one broad aspect, therefore, the present invention relates to a moulded, substantially rigid flashing for use in lining transition surfaces in construction, said flashing having a back panel, a base panel and a skirt depending from said base panel.
In drawings that illustrate the present invention by way of example:
2 l ~ 60 Figure 1 is a cross-sectional view of a flashing product according to the present invention.
Referring to Figure 1 it will be seen that the present invention provides a flashing having conventional dimensions, for application without the need for special adaption of a construction project.
The unique nature of the present invention lies primarily in that it is an extrusion moulded product, fairly stiff, but thereby precise to install with no special skills, and tough enough to resist tears. The flashing of the present invention is manufactured from a material having accepted weather resisting properties, such as polyethylene, polypropylene, or polyvinylchloride (PVC), with PVC being the preferred material.
The flashing of the present invention comprises a back panel 1, a base panel 2 and a skirt 3 being extruded in the desired size and profile, which may vary from application to application, the flashing may be provided in any length, but is conveniently provided in, for instance, 10,20 and 30 foot lengths, the largest representing a practical maximum for an uninterrupted run of brick in residential construction, and also representing a practical maximum for handling and storage.
~1 ~62~
In those instances, where it is desired to splice two lengths of flashing together, this is easily accomplished, since the flashing is made from thermoplastic materials in respect of which is a wide variety of sealants and adhesives are currently available. Splicing may be done with a cut at right angles to the longitudinal direction of the flashing.
The flashing may also be cut and adhesively spliced, using known adhesives, at 45~ (or any other suitable angle) for installing flashing around corners.
Referring again to the drawing, it will be observed that back panel l and base panel 2 may each be planar, and are of uniform thickness, although it will be understood that the two panels may be of different thicknesses. Forming a transition between the back panel l and the base panel 2 is a corner 4, which maintains the panels 1,2 at right angles. The end of skirt 3 is bent outwardly, forming a drip deflecting edge, so that water flowing down skirt 3 will not flow down the underlying surface, but will be deflected outwardly.
It is to be understood that the examples described above are not meant to limit the scope of the present invention. It is expected that numerous variants will be obvious to the person skilled in the field of construction material design and fabrication without any departure from the spirit of the ~ 21 9~1.J6~
invention. The appended claims, properly construed, form the only limitation upon the scope of the invention.
