Abstract
An integral multilayer joint seal. Layers of foam, layered co-planar to the adjacent surface, are interspersed with a barrier layer which extends beyond the foam layers to provide a protective surface, a surface for attachment atop adjacent substrates, or a connecting tab for use with adjacent joint seals. The foam layers may be uncompressed or partially compressed at the time of joint formation and may be composed of open or closed, or hybrid, cell foam. The foam may be impregnated with a fire retardant or may be composed of a fire retardant material, if desired. The barrier may have a tensile strength greater than the adjacent foam. The joint seal may have an elastomer, such as silicone, at its top and/or bottom, and may even include an elastomer layer within or about the barrier.
Claims37
A joint seal,
- comprising,
- a first substrate and a second substrate separated by a distance;
- a first body of compressible foam, the first body of compressible foam having a first body top, a first body bottom, a first body length, a first body first end, a first body width, a first body first side, a first body second side, the first body width extending from the first body first side to the first body second side, the first body width sized to the distance between the first substrate and the second substrate, the first body of compressible foam contacting the first substrate at the body first side and the second substrate at the first body second side;
- a second body of compressible foam, the second body of compressible foam having a second body top, a second body bottom, and a second body length, a second body first end, a second body width, a second body first side, a second body second side, the second body width extending from the second body first side to the second body second side, the second body width sized to the distance between the first substrate and the second substrate so as to directly contact the first substrate at the second body first side and the second substrate at the second body second side;
- a flexible barrier, the barrier having a barrier length, a barrier width, a barrier first end, a barrier first side and a barrier second side, the barrier width greater than the first body width and the second body width, the barrier including a wing extending beyond a first body first side or a second body first side,
- the barrier adhered at a barrier first surface to the first body of compressible foam at the first body bottom from the first body first side to the first body second side, the barrier first surface and the barrier second surface being coplanar from the barrier first side to the barrier second side, the barrier having an edge at the barrier first side from the barrier first surface to the barrier second surface, the barrier adhered at a barrier second surface to the second body of compressible foam at the second body top from the second body first side to the second body second side, the barrier including a layer from at least one of a heat barrier, an infrared barrier, a barrier having a tensile strength greater than a tensile strength of the first body of compressible foam and greater than the tensile strength of the second body of compressible foam, a water barrier, air barrier and a vapor barrier;
- wherein the wing of the barrier near the barrier first end is adapted to fold to contact one of the first body first side at the barrier first side and the second body first side at the barrier second side;
- the first body first end and the second body first end being co-planar;
- the first body first side and the second body first side being co-planar;
- and
- the first body second side and the second body second side being co-planar.
