Exterior wall sealing system
Abstract
A system for sealing the gaps that occur along the perimeter of a
building envelope, particularly along with installation of an
exterior finish system channel, or screed, as occurs in the
installation and application of stucco. It is common to have gaps
occur between the channel, base plate, and foundation of the
building envelope. The system utilizes a foam sealing element in
combination with the channel, caulking, a fiberglass netting that is
installed along the bottom of the channel and the face of the
foundation, and, an adhesive sealant that seals and adheres the
fiberglass netting to the foundation. The system includes several
embodiments for use in either new construction or as an aftermarket
product.

Description
BACKGROUND
This invention relates to providing a system for sealing the gaps
that occur along the perimeter of a building envelope. Typically,
constructing walls of buildings may be accomplished by a variety of
methods. One such method is to utilize wood or steel framing members
to create a framed wall. These framed walls typically consist of
framing members with a horizontal top and bottom piece (typically
referred to as a top plate and a bottom plate or base plate) and
vertical members attached from top plate to bottom plate and placed
at intervals of about 16 inches or about 24 inches (typically
referred to as studs). The bottom plate is typically attached to a
cement or wood foundation. The combination of the dependent walls
attached together and the roof create a firm structure. Depending on
the type of building and local code, the exterior of the framed
walls may be sheathed. The sheathing may be plywood, brick, stucco,
vinyl, wood or other exterior finish system. Sheets of gypsum board
or drywall are typically attached on the interior of the walls. The
sheathing also adds strength to the structure.
When the building is completed, the structure is said to have a
building envelope, which includes any component necessary to prevent
water or other weather conditions from entering the structure. The
building envelope also preferably assists in keeping out insects and
other unwanted vermin. When applying an exterior finish system, such
as, for example, stucco, foam insulation panels are often attached
to the framed wall, and then a layer of stucco is applied to the
foam. The exterior finish system is typically set in an accessory
channel (which may be herein referred to as a "screed" or "weep
screed", "weep" referring to the typical presence of some holes in
the screed to permit moisture collecting from above the screed to
exit or evaporate) attached along the bottom plate. Insulating
panels are typically placed in this channel, and a coating of stucco
material is applied over the insulating panels. During the framing
process, application of the channel, and application of the stucco,
it is common to have gaps occur in the building envelope. These gaps
are usually greatest between the channel, base plate, and
foundation.
OBJECTS OF THE INVENTION
A primary object and feature of the present invention is to provide
a system for sealing the gaps that occur along the perimeter of a
building envelope utilizing an exterior finish system and
base-plate-attached screed. It is a further object and feature of
