Benefits of technology

[0012]In accordance with a further embodiment, the applied composition has distinct properties of weather durability, vapor permeability, flexibility with no material shrinkage due to solvent loss during cure and no unusual bonding characteristics when applied to a wide variety of construction substrates under adverse conditions.

Problems solved by technology

The composition is non-flammable, releases no isocyanates, does not support mold growth, and can be subjected to precipitation directly after application.

Embodiment Construction

[0020]In the following description, certain specific details are set forth in order to provide a thorough understanding of various disclosed embodiments. However, one skilled in the relevant art will recognize that embodiments may be practiced without one or more of these specific details, or with other methods, components, materials, etc. In other instances, well-known structures or components or both associated with window and door installations and other building installations, including but not limited to double hung windows, exterior siding, and electrical and plumbing details have not been shown or described in order to avoid unnecessarily obscuring descriptions of the embodiments.

[0021]Unless the context requires otherwise, throughout the specification and claims that follow, the word “comprise” and variations thereof, such as “comprises” and “comprising” are to be construed in an open inclusive sense, that is, as “including, but not limited to.” The foregoing applies equally...

Abstract

An environmental barrier composition and method of use for forming a structural barrier system to seal structural openings such as doors and windows is provided. The composition includes a liquid rosin that is silyl-terminated polyether, a filler material, and a curing catalyst. The method includes applying the composition to a prepared through-hole in combination with flashing material at least along a bottom surface of the through-hole and installation of a window or door into the prepared through-hole to form a barrier system in which a continuous film can be easily inspected, is waterproof, meet air barrier requirements of ASTM E2178, has elastomeric properties, allows substrate expansion, contraction, and movement, does not shrink or lose volume as it cures, and cures rapidly with sufficient adhesion to transition flashing to incorporate into a designed drainage plane and allow integration of a continuous air barrier system where the barrier is at least semi-vapor-permeable.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention pertains to a substance for creating an environmental barrier and, more particularly, to a formulation and method of use for a liquid applied membrane to construct a structural barrier system that seals structural openings such as doors and windows.[0003]2. Description of the Related Art[0004]Tremendous damage to buildings, both large and small, is caused by water leaking into rough openings and framing due to faulty window and door installations or leaky windows. Owners, builders, and insurance companies can face tremendous costs in the restoration and repair of this damage. Window and door installation failure can cause delays in construction, increased insurance premiums for builders and building owners, warranty liability for builders, and increased cost of home ownership for the general population.[0005]Even when builders carefully follow detailed installation instructions and recognized trade...
