Abstract
Structural ventilated radiant barrier roofing panels are disclosed. The radiant barrier roofing panels have panel with a first side formed with a plurality of channels and covered with a perforated radiant barrier to form a flow path. When installed on a structure, the radiant barrier roofing panels form a flow path from inside the attic, through the perforations, through the channels, and through abutment spaces between adjacent panels to allow for ventilation of the attic. Methods of ventilating an attic of a structure using radiant barrier roofing panels and of manufacturing radiant barrier roofing panels are also disclosed.
Claims19
A radiant barrier roofing panel comprising:
- a panel having a first and a second side, wherein the panel is formed with a plurality of channels on the first side of the panel;
- a radiant barrier comprising a foil layer, wherein the foil layer has a first side and a second side;
- wherein the second side of the foil layer of the radiant barrier is coupled to the first side of the panel and the radiant barrier extends across the plurality of channels to form ventilation pathways;
- and
- wherein the radiant barrier is perforated at least over the plurality of channels.
A method for ventilating an attic comprising the steps of:
- attaching a plurality of radiant barrier roofing panels to a plurality of rafters of an attic, wherein each of the plurality of radiant barrier roofing panels comprise:
- a panel having a first and a second side, wherein the panel is formed with a plurality of channels on the first side of the panel,
- a radiant barrier comprising a foil layer and a carrier layer, wherein the foil layer has a first side and a second side and the carrier layer has a first side and a second side, wherein the second side of the foil layer is coupled to the first side of the carrier layer,
- wherein the second side of the carrier layer of the radiant barrier is coupled to the first side of the panel and the radiant barrier extends across the plurality of channels to form ventilation pathways, and
- wherein the radiant barrier is perforated at least over the plurality of channels;
- and
- installing roofing material over the second side of each of the plurality of radiant barrier panels;
- wherein the plurality of radiant barrier roofing panels is installed with the radiant barrier facing the attic;
- wherein at least two radiant barrier panels are installed adjacent to each other on the same rafter with an abutment gap between the two adjacent radiant barrier panels;
- wherein for at least one radiant barrier panel at least one perforation of the radiant barrier and at least one of the plurality of channels are in fluid communication with each other and the at least one of the plurality of channels is in fluid communication with the abutment gap, to form a flow path for vapors to travel from the attic to the second side of the panels.
A vented radiant barrier roofing panel comprising:
- a panel formed with a plurality of channels on one side running along a dimension of the panel and having a thickness of at least 0.25 inches;
- a radiant barrier coupled over the plurality of channels of the panel to form a plurality of ventilation pathways;
- and
- wherein at least a portion the radiant barrier is perforated over the plurality of channels to provide fluid transfer through the plurality of channels.
