Abstract
A sealing component is disclosed that is installed across an uneven surface without having dedicated segments for engaging raised and recessed portions of the uneven surface. The sealing component may include an elongated strip of compressible nonwoven material. The elongated strip may include an adhesive on one or two sides. In a pre-installation configuration, the strip may be wound into a coil.
Claims19
A ventilation system component for use with a roof panel having an uneven surface, comprising:
- an elongated strip of air-permeable compressible nonwoven material formed from a plurality of fibers, said plurality of fibers comprising polyester, nylon, polyethylene, or polypropylene fibers, said strip having a first side opposite a second side, each side having a substantially continuous planar surface and the strip having a substantially constant cross-section of the material from a top of the strip downward when the strip is not in use and one of the first side or the second side being conformable to and in substantially continuous engagement with the roof panel having an uneven surface without having dedicated segments to engage the uneven surface and the other of the first side or the second side in substantially continuous engagement with an opposing roof panel when the strip is in use;
- and
- an adhesive layer disposed on at least one side of the elongated strip of air-permeable compressible nonwoven material.
A method of installing a ventilation system component, comprising:
- applying an elongated strip of compressible air permeable nonwoven material to a major roof panel, the elongated strip of nonwoven material having a first side opposite a second side, each side having a substantially continuous planar surface and the strip having a substantially constant cross-section of the material from a top of the strip downward when the strip is not in use and one of the first side or the second side conforming to and in substantially continuous engagement with one or more irregularities on the surface of the major roof panel without having dedicated segments to engage the irregularities and the other of the first side or the second side in substantially continuous engagement with a minor roof panel when the strip is in use;
- and
- attaching the minor roof panel to the major roof panel, wherein a portion of the minor roof panel is in contact with the elongated strip of nonwoven material.
A method of installing a ventilation system component, comprising:
- applying a first elongated strip of compressible air permeable nonwoven material to a minor roof panel;
- and
- attaching the minor roof panel to a major roof panel, wherein a portion of the major roof panel is in contact with the first elongated strip, wherein the first elongated strip has a first side opposite a second side, each side having a substantially continuous planar surface and the strip having a substantially constant cross-section of the material from a top of the strip downward when the strip is not in use and one of the first side or the second side substantially conforms to and is in substantially continuous contact with one or more irregularities on the surface of the major roof panel without having dedicated segments to engage the irregularities and the other of the first side or the second side is in substantially continuous contact with the minor roof panel when the strip is in use.
