Condensation management techniques for a gas flow delivery system. The techniques include providing a radiant barrier associated with patient circuit and/or a patient interface, providing a water trap and/or an absorbent insert in the patient interface device, or a combination of these techniques. The radiant barrier prevents condensation from forming in the patient circuit and/or the patient interface. The water trap and absorbent insert in the patient interface control condensation that reaches or forms in the interior of the patient interface to prevent it from interfering the user of the gas delivery system.

A dual air cavity roof has a continuous upper cavity which is cooled by fans, while the lower cavity is generally sealed. Preferably the cavities are separated by a radiant barrier. The fans are preferably powered by one or more photovoltaic cells that are also disposed on the roof. The roof can be pre-cooled with cooler night air and fans only activated when necessary to remove heat from the solar load on the upper cavity. When it is desirable to remove heat, the fan speed is optimized in each zone of the roof to enhance the natural convective flow to the optimum level. A radiant barrier can also cover the roof substrate, which is optionally an existing roof that is in need of repair. The roof structure is preferably assembled in parallel modules using insulating support brackets that support the outer surface and the barrier that separates the upper and lower cavity.

A method and apparatus for enclosing a user is provided. The user is shielded from the ambient conditions existing outside a portable enclosure. The enclosure includes an insulation system. The insulation system includes a radiant barrier.

A radiation barrier for shielding a person from radiation emitted from a radiation source. The barrier includes a radiopaque wall extending between opposite lateral edges, wherein the wall is positionable between the radiation source and the person to prevent radiation from traveling directly between the radiation source and the person, and a radiopaque deflector extending from the wall and obliquely angled relative to the wall.

A constructed enclosure, adjacent to an interior habitable space, uses a microprocessor-based control unit to operate enclosure openings to provide a multi-layer insulation barrier containing or creating heat, or providing a radiant barrier, isolating by open air, a thermal insulating layer from warm exterior surfaces, maximizing insulation values. The enclosed space, through the use of openings, which in one embodiment are windows, skylights and dampers connected to louvers, is heated by radiant exposure or cooled by natural air flow or exhaust fan. Return air is heated upstream from a forced air heating unit by traversing ductwork heated by the enclosure and by direct solar exposure from enclosure windows. Enclosure openings to the habitable interior spaces create air displacement drawing warm air out of the interior and fresh air in through exterior windows. The energy efficient system is tailored for immediate climate specific conditions.

The method of this invention adheres a low emissivity radiant barrier material to an underlying lignocellulosic substrate within the primary manufacturing operation of the underlying lignocellulosic substrate. Thus, a radiant barrier covered substrate is formed by integrally joining the radiant barrier covering to a mat of lignocellulosic material during consolidation thereof with a first adhesive bonding material to form an underlying substrate. The integral joining operation can, for example, be accomplished by bonding the radiant barrier covering to a lignocellulosic mat in a product formation press. This is typically accomplished using a second adhesive bonding material for adhesion of the radiant barrier material to the lignocellulosic mat, and a first adhesive bonding material for consolidating the lignocellulosic mat to form a lignocellulosic substrate. More specifically, this invention is directed to a method whereby a low emissivity radiant barrier material is joined in situ to a mat of lignocellulosic particles using a second adhesive material, during the consolidation of the lignocellulosic particles and a first adhesive bonding material to form an underlying substrate, an integral laminated radiant barrier covered lignocellulosic product being produced.

Insulated Fabric Pocket Panels were designed to provide safe, economical, portable energy saving insulation for the interior living spaces of un-insulated or under insulated structures. The embodiments inserted into the fabric pocket panel include the following but not limited to either one layer of double bubble reflective foil insulation (15), an insulation bundle (25) or foil radiant barrier (28) inserted inside the pocket.

The insulated fabric pocket panels insulate against heat and cold transfer through perimeter interior surfaces from outside weather. Heat and cold are reflected out of the interior of the structure to the outside environment. The reflective foil on the interior side of the panel reflects heated furnace air or cooled air conditioning air away from interior surfaces back into the interior or center of the rooms. Furnaces or air conditioners do have to heat or cool the interior finished wall surfaces. Only the air is heated or cooled. This process uses less energy, saves money, and protects the environment.

Due to climate change, rising oil prices, stagnated wages and an increase in low-wage earners, environmental experts have said that within the next ten to fifteen years 30% of all Americans will not be able to heat or cool their residences. No American family should have to choose between heating or cooling their residence and buying food or medication(s). These panels are essential to middle class families, the elderly and disabled on fixed incomes, and poverty stricken families because they reduce energy use, save money and help protect the environment.

The present invention provides a flexible heat reflective radiant barrier that may be conveniently installed on a structure without the need to simultaneously replace rigid construction decking panels. The flexible heat reflective radiant barrier is for use as part of the outer-protective water-shedding materials of a structure or building, such as underneath shingles, tiles, or siding. At least one heat reflective layer is adhered to at least one layer of a felt roofing material. The flexible heat reflective radiant barrier may be disposed in rolls for case of storage and handling. The rolls are easily applied to rigid construction decking panel substrates, such as plywood or oriented strand board construction sheets of structural 2×4, 2×6 side walls or the like, as a part of the exterior water-shedding material.

The flexible liner comprises a sealing layer and a radiant barrier disposed on the sealing layer.

A baffle system that can be used to provide ventilation to attics and roofs at the time of new roof construction or retrofit and further provides for solar thermal energy control and harvesting systems in conjunction or combination with the baffle systems. According to one embodiment, the baffle vents are made from a resilient material and are designed and configured to be flexed into a deformed shape, positioned between adjacent roof rafters and released whereupon the baffle vents become wedged between adjacent roof rafters. According to another embodiment the baffle vents have side edge portions that are configured to extend over the upper portions of roof rafters and thereby support the baffle vents between adjacent roof rafters. The baffle vents can function as radiant barriers by providing the baffle vents with a reflecting coating(s) or reflective surface(s). The baffle vents can function as radiant collectors by positioning solar thermal collectors in the air flow channels defined by the baffle vents and darkening the lower surface of the roof sheeting plane. Stock baffle vents are configured to provide for insulation dams that can be cut from the ends of the baffle vents.
