This invention relates to a system of ventilating a residential structure with lightweight, easy to install radiant barriers that reflect external sunlight heat away from the structure, reflect heat produced within the structure to maintain internal warmth, and contain internal air ventilation space to prevent condensation.
BACKGROUND OF INVENTION
Maintaining internal temperatures within residential and light commercial buildings can be accomplished through several avenues passively working in concert. Proper construction of the building roof, walls, ceiling, and attic structures can provide adequate air ventilation to prevent heat condensation and space for insulation to prevent thermal loss. Properly maintained insulation can prevent thermal transfer from the internal structure to the external environment. Active heating and cooling systems, such as furnaces and central air conditioners, can bolster these passive temperature systems, but are costly to run and supply with electricity, gas, or oil.
Many older residential and light commercial structures have poor insulation construction and internal air flow, resulting in extensive heat loss during colder seasons, and extensive overheating from sunlight during warmer seasons. It is quite costly to maintain internal temperatures for these structures. Furthermore, these older buildings often have unique roof and ceiling structures that require extensive time, labor, and costs to properly insulate with air gaps for proper air ventilation. Many older buildings have different widths between each roof rafter, requiring insulation of different widths. Creating each air gap usually requires individually cutting pieces of lumber and nailing them in the corners of the roof rafters and the roof plywood.
Many of the current solutions for passively maintaining internal temperatures within residential and light commercial buildings are faulty in allowing thermal transfer, air infiltration, and heat condensation which results in structural decay through mold and mildew growth. Furthermore, many of the current solutions do not provide a method of reflecting back external sunlight heat, which causes structures to overheat in warmer seasons and climates.
The system of the present invention contains provides many benefits to the construction of residential and commercial buildings, including, but not limited to:
low-cost installation; easy installation; installation into older and uneven roof structures; external passive heat reflection reflecting sunlight in warmer environments; internal passive heat reflection reflecting sunlight in colder environments; built-in air ventilation providing adequate air flow; providing high thermal resistance; preventing thermal bridging; providing increasing protection against water damage, vapor damage, decay damage, mold or mildew damage, frost damage and insect damage; and the absence of any toxic compounds. In addition, the system is lightweight for transport and construction and compatible with existing plumbing, wiring, roofing, exterior and interior finishes commonly used.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description of an improved toddler gate. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto. These together with other objects of the invention, along with the various features of novelty, which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
Advantages of the present invention will be apparent from the following detailed description of embodiments of an improved toddler gate, which description should be considered in conjunction with the accompanying drawings, in which:
While several variations of the present invention have been illustrated by way of example in particular embodiments, it is apparent that further embodiments could be developed within the spirit and scope of the present invention, or the inventive concept thereof. However, it is to be expressly understood that such modifications and adaptations are within the spirit and scope of the present invention, and are inclusive, but not limited to the following appended claims as set forth.
As illustrated in
Each radiant barrier 1 comprises a substantially flat rectangular or square base 3 with a first surface 4, a second surface 5, a top edge 6, a bottom edge 7, a side edge 8, a side edge 9, and multiple substantially parallel fold lines 10 to produce an accordion like cross-section 11 with a plurality of adjacent oppositely pointing apexes 12 on each surface 4 and 5, with a plurality of substantially flat parallel rectangular top surfaces 13, and a plurality of substantially flat parallel rectangular bottom surfaces 14. The base 3 is collapsible along the fold lines 10. The radiant barriers 1 have very little volume when collapsed and can be stored and transported in this condition.
The base 3 comprises a foam board core 15, which prevents deterioration. The core 11 may vary in thickness from 1/32 inch to 1 inch.
Each surface 4 and 5 is covered with a substantially fireproof thin and flexible metal leaves, such as Mylar sheet or aluminum metal sheets to reflect radiant heat. Surface 4 faces upward from the roof rafters, or outward in the walls, during installation to reflect radiant heat from external sunlight to prevent heat conduction from the roof. This prevents the building from overheating due to external radiant energy from sunlight. Surface 5 faces downward from the roof rafters, or inward in the walls, during installation to reflect radiant heat from into the house for winter heating. This maintains the internal warmth generated within the building.
The radiant barrier's 1 accordion like cross-section 11 creates air space on both surfaces 4 and 5 between all apexes 12. The air space between the roof and the surface 4 helps reflect radiant heat energy. During colder seasons, the air space between the roof and the surface 5 provides ventilation to prevent condensation. The base 3 further comprises a plurality of traversing air holes 16 on the plurality of substantially flat rectangular top surfaces 13, and a plurality of substantially flat rectangular bottom surfaces 14. These air holes 16 permit air flow between surfaces 4 and 5 to allow moisture to escape, preventing heat condensation on the base 3 and the roof rafters 2.
The radiant barrier 1 is easy to install by attaching it directly onto roof rafters 2, without the need to create air gaps during installation. The radiant barrier 1 can be installed on roof rafters 2 and attached in substantially parallel positions between side edges 8 and 9, or attached between top and bottom edges 6 and 7. During installation, the radiant barrier 1 surfaces 4 and 5 can overlap in substantially parallel, overlying positions along edges 6, 7, 8, or 9, and can be stacked in substantially parallel, overlying positions to permit a good fit between rafters 2. The width of the base 3 may vary to fit a standard 16″ center roof rafter, or expanded to fit unique or uneven roof rafter widths. The angle of each apex 12 may vary from 0 degrees to 180 degrees depending on the expansion of the radiant barrier during installation. During installation, there is no need to prepare additional air gaps, as the radiant barrier 1 structure has the air gaps built-in.
The radiant barrier 1 may also be installed within wall structures without the need to create air gaps during installation. As with the roof rafters, the radiant barrier 1 can be installed within a wall frame in substantially parallel positions between side edges 8 and 9, or attached between top and bottom edges 6 and 7. During installation, the radiant barrier 1 surfaces 4 and 5 can overlap in substantially parallel, overlying positions along edges 6, 7, 8, or 9, and can be stacked in substantially parallel, overlying positions to permit a good fit between wall frames. The angle of each apex 12 may vary from 0 degrees to 180 degrees depending on the expansion of the radiant barrier during installation. During installation, there is no need to prepare additional air gaps, as the radiant barrier 1 structure has the air gaps built-in.
Surface 4 faces outward in the walls, during installation, to reflect radiant heat from external sunlight to prevent heat conduction from the wall siding. This prevents the building from overheating due to external radiant energy from sunlight. Surface 5 faces inward in the walls, during installation, to reflect radiant heat from into the house for winter heating. This will allow the house to breath, prevent wall insulation from overheating in the warner environments, and require less active cooling from air conditioner systems. In colder seasons, the radiant barrier 1 reflects the radiant heat from the house back into the building. This will help reduce active heating from furnaces.
The many aspects and benefits of the invention are apparent from the detailed description, and thus, it is intended for the following claims to cover such aspects and benefits of the invention, which fall within the scope, and spirit of the invention. In addition, because numerous modifications and variations will be obvious and readily occur to those skilled in the art, the claims should not be construed to limit the invention to the exact construction and operation illustrated and described herein. Accordingly, all suitable modifications and equivalents should be understood to fall within the scope of the invention as claimed herein.
This application claims the benefit of U.S. Provisional Patent Application No. 62/221,702, filed on Sep. 22, 2015, the contents of which are incorporated herein by reference.
