Abstract
An integral multilayer joint seal system. Layers of foam, layered co-planar to the adjacent surface, are interspersed with a barrier layer. 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 and may be different in dimensions from the layers of foam. The joint 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.
Claims27
A joint seal system, comprising:
- a joint, the joint having 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, and a first body second side;
- the first body width sized to the distance between the first substrate and the second substrate so as to directly contact the first substrate at the first 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, and a 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 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 adhered to the first body of compressible foam at the first body bottom, the barrier adhered to the second body of compressible foam at the second body top, the barrier including a layer from at least one of a heat barrier, an infrared barrier, a high tensile barrier, a water barrier, air barrier and a vapor barrier;
- 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.
A joint seal for imposition under compression between a first substrate and a second substrate separated by a distance,
- comprising
- 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, and a first body second side;
- the first body width sized to the distance between the first substrate and the second substrate so as to contact the first substrate at the body first side;
- a second body of compressible foam, the second body of compressible foam having a second body top, a second body bottom, a second body length, a second body first end, a second body width, a second body first side, and a second body second side;
- the second body width sized to the distance between the first substrate and the second substrate;
- a 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 adhered to the first body of compressible foam at the first body bottom, the barrier adhered to the second body of compressible foam at the second body top, the barrier including a layer from at least one of a heat barrier, an infrared barrier, a high tensile barrier, a water barrier, air barrier and a vapor barrier;
- 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;
- wherein the barrier is composed of copper having a sinusoidal shape between the first body first side and a second body second side opposite the first body first side.
