Abstract
A vapor barrier system includes two or more vapor barrier elements, each of which includes a vapor barrier layer, adhesive layer and removable protective layer to selectively cover and uncover the adhesive layer. The vapor barrier layer may have a desired shape and may be combined with other similarly shaped vapor barrier elements or with complementary shapes vapor barrier elements to ensure a seal around the pipe or fitting.
Claims20
A vapor barrier system comprising:
- a plurality of vapor barrier elements;
- each vapor barrier element of the plurality of vapor barrier elements including two narrow ends connected be a widened area and including:
- a vapor barrier material layer;
- an adhesive layer provided on a bottom surface of the vapor barrier material later;
- a protective layer removably attached to the adhesive layer;
- and
- an overlap area provided along an edge thereof and along one narrow end, configured to be covered when in use on a pipe fitting;
- wherein a first vapor barrier element of the plurality of vapor barrier elements is provided on a top portion of a pipe fitting with the widened area covering an outer portion of the pipe and the two narrow ends wrapping around the pipe fitting toward the throat area;
- a second vapor barrier element of the plurality of vapor barrier elements is provided on a curved portion of the pipe fitting with a second widened area covering an outer portion of the pipe fitting and two second narrow ends wrapping around the pipe toward the throat area such that the second vapor barrier element covers a first overlap area of the first vapor barrier element;
- a third vapor barrier element of the plurality of vapor barrier elements is provided on a lower portion of the pipe fitting with a third widened area covering an outer portion of the pipe and two third narrow ends wrapping around the pipe toward the throat area such that the third vapor barrier element covers a second overlap area of the second vapor barrier element.

A vapor barrier system comprising:
- a first vapor barrier element including multiple segments joined together to provide an outer sleeve configured for placement on an outer surface of a pipe fitting;
- a second vapor barrier element including multiple segments joined together to provide an inner sleeve configured for placement on a throat of the pipe fitting;
- wherein the first vapor barrier element and second vapor barrier element include:
- a vapor barrier material layer;
- an adhesive layer provided on a bottom surface of the vapor barrier material later;
- and
- a protective layer removably attached to the adhesive layer;
- wherein the second vapor barrier element includes an overlap area provided along a lateral edge thereof and configured to be covered when in use on a pipe fitting, and
- wherein the first barrier element covers the overlap area of the second barrier element when the first barrier element and second barrier element are in place.
6 more elements
A vapor barrier system comprising:
- a first vapor barrier element having an X shape;
- a second vapor barrier element having an H shape;
- wherein a longitudinal centerline of the first vapor barrier element covers a throat of a pipe fitting with the legs of the X shape wrapping around the pipe fitting toward a heel of the pipe fitting, and
- a horizontal centerline of the second vapor barrier element is provided along a centerline of the outer curve with the legs and a remainder of the center wrapping toward the throat of the pipe fitting.
1 more element
A vapor barrier system comprising:
- a first vapor barrier element having a central strip and a plurality of fingers extending away from the central strip;
- and
- a second vapor barrier element having a butterfly shape;
- wherein the first vapor barrier element is provided with the central strip aligned with a centerline of the outer curve of a pipe fitting and the fingers wrapping around the pipe toward a throat, and
- the second vapor barrier element covers the throat of the pipe fitting with a central portion thereof and the end portions wrapping around the pipe to overlap with the fingers of the first vapor barrier.
