Abstract

A laminate system for use in building construction adapted to be positioned between a substrate material and an exterior material to avert the passage of water between the exterior material and the substrate material. The laminate system includes any combination of a rigid backer, a gasket, one or more substantially waterproof/water-resistant membrane, and one or more peel away sheets entirely covering the one or more membranes.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates, generally, to laminate systems for use in building construction. More specifically, it relates to a laminate or gasket system for use in waterproofing the exterior building envelope.

2. Description of the Prior Art

Laminates are known in the prior art. While laminate systems fulfill their respective, particular objectives and requirements, laminate systems that adequately prevent water from penetrating substrate materials do not exist.

Unsuccessful attempts have been made at preventing moisture from penetrating substrate materials, examples being U.S. Pat. No. 7,721,488 (“Bennett”) and U.S. Pat. No. 5,065,553 (“Magid”). Bennett discloses a flashing apparatus that intends “to provide a certain level of water resistance in the seams between the ends of the sections of the siding.” (abstract, Bennett). Bennett includes a flashing panel, but does not provide sufficient water resistance since no seal, gasket or drain trough is created between the flashing panel and exterior material, thereby allowing penetration of moisture. Magid discloses a roof flashing unit with a flexible waterproof membrane. The membrane remains on the exterior of the roof flashing unit, so the membrane is the roofing material. Significant issues arise in Magid, including that the waterproof membrane is exposed to climatic conditions and attempts to block the conditions from the underneath metal sheet using one membrane that is substantially the same size as the metal sheet. This is insufficient, as a seal, gasket or drain trough is not created between the sheet and exterior material, and moisture and other debris would tend to leak into the flashing and substrate materials.

Therefore, it can be appreciated that there exists a long felt but unfulfilled need for a new and improved laminate system that can prevent water from penetrating substrate materials. However, in view of the prior art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the art how the limitations of the art could be overcome, including how a laminate system could prevent water from penetrating substrate materials.

While certain aspects of conventional technologies have been discussed to facilitate disclosure of the invention, Applicants in no way disclaim these technical aspects, and it is contemplated that the claimed invention may encompass one or more of the conventional technical aspects discussed herein.

The present invention may address one or more of the problems and deficiencies of the prior art discussed above. However, it is contemplated that the invention may prove useful in addressing other problems and deficiencies in a number of technical areas. Therefore, the claimed invention should not necessarily be construed as limited to addressing any of the particular problems or deficiencies discussed herein.

In this specification, where a document, act or item of knowledge is referred to or discussed, this reference or discussion is not an admission that the document, act or item of knowledge or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge, or otherwise constitutes prior art under the applicable statutory provisions; or is known to be relevant to an attempt to solve any problem with which this specification is concerned.

SUMMARY OF INVENTION

The long-standing but heretofore unfulfilled need for an improved laminate system that can prevent water from penetrating substrate materials is now met by a new, useful, and nonobvious invention.

Generally speaking, the laminate system is used during building construction to avert the passage of water between an exterior material and a substrate material.

In a first embodiment, the laminate system includes a substantially waterproof/water-resistant membrane disposed on a generally rigid backer.

In a second embodiment, the laminate system includes a substantially waterproof/water-resistant membrane disposed in overlying relation to a resilient material that is disposed in overlying relation to a generally rigid backer. The resilient material is disposed between the rigid backer and the substantially waterproof/water-resistant membrane. As the laminate system is sandwiched between the substrate material and exterior material, the resilient material compresses. The recoil of the resilient material ensures that the substantially waterproof/water-resistant membrane is securely forced against the exterior material regardless of imperfections or voids in the exterior material.

In a third embodiment, the resilient material is disposed in overlying relation to a first side of the rigid backer and the substantially waterproof/water-resistant membrane is disposed in overlying relation to a second side of said rigid backer. A second substantially waterproof/water-resistant membrane may additionally be disposed in overlying relation to the resilient material.

In a fourth embodiment, the laminate system may include a peel away sheet disposed in overlying relation to the substantially waterproof/water-resistant membrane. The peel away sheet is removed at the time of installation to expose the adhesive properties that the substantially waterproof/water-resistant membrane may contain.

In a fifth embodiment, the laminate system includes a plurality of substantially waterproof/water-resistant membranes disposed in overlying relation to a first side of a rigid backer. In a further embodiment, peel away sheets may be disposed in overlying relation to the plurality of substantially waterproof/water-resistant membranes. The peel away sheets are removed at the time of installation to expose the adhesive properties that the substantially waterproof/water-resistant membrane may contain.

The laminate system can vary in shape and size depending on the task, for example butt joint flashings and trim flashings. In a particular embodiment, the laminate system includes a hidden butt joint flashing system. The hidden butt joint flashing system includes a flashing panel having a substantially waterproof/water-resistant membrane secured in overlying relation to a front surface of the flashing panel. A peel away sheet can cover the substantially waterproof/water-resistant membrane.

The upper edge of the flashing panel may be bent forward to form a downward 45 degree angle with the flashing panel. Moreover, a top flange may project from an upper edge of the flashing panel and is angled between 0-45 degrees. Additionally, a top flange may be bent forward to form a 90 degree angle with the flashing panel. The top flange may further include a nail hole.

These and other important objects, advantages, and features of the invention will become clear as this disclosure proceeds.

The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts that will be exemplified in the disclosure set forth hereinafter and the scope of the invention will be indicated in the claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part thereof, and within which are shown by way of illustration specific embodiments by which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the invention.

In an embodiment, the laminate system, or assembly, includes a combination of two materials laminated together to create a gasket system using a rigid backer, being a flashing panel, and one or more substantially waterproof/water-resistant membranes. The rigid backer can be made of any metal, plastic, synthetic product or other suitable material and can be bent in any fashion. For example, the backer can be bent or formed for use as a butt joint flashing and/or trim flashing.

Accordingly, in an example embodiment, the laminate system may include a rubberized waterproof membrane laminated to a shaped aluminum backer. The aluminum acts as a rigid backer for the membrane so the membrane can create a tight seal between the aluminum backer and an exterior material, creating a seal or gasket, to avert the passage of water between the exterior material and a substrate material. The membrane may also act as an adhesive surface.

The substantially waterproof/water-resistant membrane may be any suitable waterproof/water-resistant material. For example, the substantially waterproof/water-resistant membrane may include rubber, rubberized asphalt, foam, silicone, synthetics, EPDM (ethylene propylene diene monomer) or any other suitable material, individually or in combination, to avert the passage of moisture.

A peel away sheet may be disposed in overlying relation to the substantially waterproof/water-resistant membrane and removed at the time of installation to expose the adhesive properties, if any, of the substantially waterproof/water-resistant membrane. If more than one substantially waterproof/water-resistant membrane is present on the device, peel away sheets may be disposed in overlying relation to one or more of the membranes. If the substantially waterproof/water-resistant membrane does not include adhesive properties, a peel away sheet is not needed but may nevertheless be included.

In another embodiment, the laminate includes a combination of two materials laminated together to create a gasket system using a rigid backer, a resilient material, and a substantially waterproof/water-resistant membrane. The rigid backer can be made of any metal, plastic or synthetic product and can be bent in any fashion. For example, the backer can be bent or formed for use as a butt joint flashing and/or trim flashing. Likewise, the substantially waterproof/water-resistant membrane and gasket can be any otherwise suitable material to avert the passage of water, including, but not limited to, rubber, foam, silicone, synthetics, and EPDM, individually or in combination. The gasket may be any suitable size desired by the user, for example ¼″×¼″, and can be any desired shape, such as a square cross section, as depicted herein.

If a resilient material is used, it can be disposed between the rigid backer and the peel away sheet. The resilient material compresses as the laminate system is sandwiched between the substrate material and exterior material after the peel away strip has been removed. The recoil of the resilient material ensures that the substantially waterproof/water-resistant membrane is securely forced against the exterior material, creating a seal or gasket, regardless of imperfections or voids in the exterior material. It is also contemplated that the resilient material can be disposed between the rigid backer and the substantially waterproof/water-resistant membrane. A second substantially waterproof/water-resistant membrane may additionally be disposed in overlying relation to the resilient material.

The resilient material can be any suitable resilient material, for example compression foam, plastics, synthetics or other suitable material. The resilient material may be any thickness and resiliency necessary to ensure sufficient recoil for pressing the substantially waterproof/water-resistant membrane against the exterior or substrate material.

The novel laminate system is used in building construction and can be sandwiched between a substantially planar substrate and a substantially planar exterior surface covering. The substrate can be any suitable materials used in building construction, such as stucco, plywood, any wall sheathing, etc. The exterior surface covering can be any suitable materials, such as cement fiber, vinyl, wood composite products, aluminum, etc. The laminate system may create a seal and/or interstitial drain trough between the rigid backer and exterior surface covering via the substantially waterproof/water-resistant membranes. The system can be used without the membranes as well to avert the passage or accumulation of moisture.
