Abstract
An application for an arced sealing tape has a bottom, an inner wall and an outer wall. The surfaces of the inner wall and the outer wall that are closest to a center point of the arc have an adhesive. Likewise, a bottom surface of the bottom also has an adhesive.
Claims20
A tape for sealing duct work, the tape forming an arc with respect to a center point, the tape comprising:
- a planar bottom, a curved planar outer wall distal from the center point and a curved planar inner wall closer to the center point, the planar bottom having a bottom surface distal from the curved planar outer wall and the curved planar inner wall, the planar bottom having a first curved edge and a distal second curved edge;
- whereas the first curved edge interfaces to a first edge of the curved planar outer wall and the second curved edge interfaces to a first edge of the curved planar inner wall, thereby forming a U-shaped cross section.
A method of sealing a take-off to a collar nipple, the collar nipple installed in a surface of a heating/air-conditioning box/run, the method comprising:
- providing a tape, the tape forming an arc with respect to a center point, the tape comprising:
- a planar bottom, a curved planar outer wall distal from the center point, and a curved planar inner wall closer to the center point, the bottom having a bottom surface distal from the curved planar outer wall and the curved planar inner wall, an edge of the curved planar outer wall interfaced to a first curved edge of the planar bottom and an edge of the curved planar inner wall interfaced to an opposite curved edge of the planar bottom, thereby forming a U-shaped cross section;
- a first adhesive layer disposed on an inner surface of the curved planar outer wall, the inner surface of the curved planar outer wall being a surface of the curved planar outer wall closest to the curved planar inner wall;
- a second adhesive layer disposed on an inner surface of the curved planar inner wall, the inner surface of the curved planar inner wall being a surface of the curved planar inner wall closest to the center point;
- and
- a third adhesive layer disposed on the bottom surface of the planar bottom;
- pulling a vapor barrier and an insulation layer back from an end of a duct core of the take-off duct;
- fitting the end of the duct core over the collar nipple;
- wrapping a band over the end of the duct core;
- tightening the band;
- affixing the first adhesive layer to the circumference of the collar nipple covering at least part of the collar nipple and part of the end of the duct core;
- affixing the second adhesive layer to the box/run around the collar;
- pushing the insulating layer and the vapor barrier into the tape between the curved planar inner wall and the curved planar outer wall;
- and
- affixing the third adhesive layer to the vapor barrier.
12 more elements
A tape for sealing duct work, the tape forming a U-shape, the tape comprising:
- a bottom, an outer wall and an inner wall, the bottom having a bottom surface distal from the outer wall and the inner wall, an edge of the outer wall interfaced to a first edge of the bottom and an edge of the inner wall interfaced to an opposite edge of the bottom, thereby forming a U-shaped cross section;
- and
- embosses formed in at least one of the bottom, the outer wall and the inner wall.
