The invention relates generally to a window system that is able to effectively insulate heat. It is the objective of the present invention to insulate heat as well as allow the user to be able to see through the window while adjusting what direction the viewer can see in.
With limited natural resources, energy providers are beginning to charge real estate owners more for their services. To compensate for the increase in energy prices, energy efficient products are constantly being developed. Even methods of constructing homes and buildings are changing to become more energy efficient. A direction for contractors to make buildings more energy efficient is to include energy efficient windows. There have been many windows developed that minimize heat transfer by increasing the insulation. Among these windows are insulated glazing units, which include two or more panes of glass separated by a spacer frame. Within the frame and panes of glass is sealed an insulating gas which increases the R-value and U-factor of the window. This allows for increased insulation and is moderately energy efficient. When finishing these insulated glazing units, developers have often tried to increase the insulating properties by using different materials for sealants, spacers or even adding coatings to the glazing. However, replacing different materials for the insulated glazing units only had mediocre effects on the insulating properties of the window. To make a significant increase in insulating properties, rather than the use of gasses to fill the insulating glazing units, aerogel particles was used.
The U.S. Pat. No. 4,831,799 introduces a multi-layered insulated glazing unit that can be filled with insulating gasses. This type of insulating glazing unit does not make use of the compound aerogel.
The U.S. Pat. No. 7,641,954 introduces a panel and glazing system that makes use of non-optimizable thermoplastic panels that is not adjustable with continuous internal channels that are able to hold aerogel compound. The insulated glazing system proposed in this patent makes use of two U-shaped elements to create spacing to bind the thermoplastic panels for insulation. The insulated glazing system instead of using two flat glass panes with spacers and sealants makes use of U-shaped glass elements to seal the insulating panel. This invention is a non-optimizable continuous vessel system that is non-adjustable.
The United States Patent H975 introduces a non-optimizable, non-adjustable continuous thermal insulated glazing unit that makes use of aerogel particles to fill the thermal gaps within the glazing unit. However, aerogel is only translucent and not transparent, leaving the user unable to see through.
The United States Patent Application Publication 2007/0122588 A1 introduces a non-optimizable, non-adjustable glazing unit with a continuous honeycombed structure to contain silica aerogel particles. However, again the aerogel is used to fill all the compartments and reduces the ability of a user to see through.
The U.S. Pat. No. 4,950,344 introduces a method of manufacturing a multiple-glass-pane glazing unit having a thermo-set structural silicone foam spacer serving as a thermal break. The structural foam spacer is located at the peripherally of the glass panes only. The structural foam spacer is not bound by the glazing's actual design by itself The structural foam spacer is bonded only by adhesives. This method bonds poorly when glazing of glass is replaced by polycarbonate glazing. This invention is only bonded effectively at the periphery of panes made of glass, whereas later in the manufacturing process a necessary supporting window frame typically made of wood, vinyl, metal or fiberglass may be utilized to further insure necessary structural integrity of the thermal breaking structural foam spacer. Polycarbonate is far more flexible than glass when faced with wind load and is harder to bond to. This invention therefore does not include interlocking structural foam serving as a thermal break spacer that is bound in anyway by the glazing's actual design in itself.
A commercial product which involves the enclosure of aerogel in polycarbonate vessels is used as day-lighting windows. These daylighting windows do not allow users to clearly see through the windows. None of the prior art stated above with aerogel allow a user to see through and does not allow a user to have control over what direction they can see through the window system.
The following technical features of the present invention will be appreciated by those of skill in the art. The invention is a optimizeable view through gel enhanced IGU lenses system, a insulating lenses system insert that transmits and/or refracts light that can be used for the optimization of these multiple benefits: Provides engineers the benefit of manipulating, therefore optimizing, performance in regard to heat transfer, soundproofing, light diffusion, light penetration, light density, ultraviolet (UV) light filtration, light distribution, light glare, security, privacy, solar rays, user viewing direction, and range that windows can be viewed into and out through based on their specifications. The geometric glazing optimization possibilities of the present invention far exceed all other prior art. The vessels can be manufactured to any shape or design within the parameters of the IGU cavity. In addition, the at least one cavities inside the vessel inserts can be mold injected into any shape to have square, trapezoid, polygon, honeycombed or other patterns. Existing art is typically extruded and only provides vessels with limited geometric possibilities where the walls are continuous following a single direction. The mold injection method offers the vessel to be manufactured with intersecting walls of different shapes for far more geometric benefits and effects. View through areas can be hollow meaning a hole clear through, 100% solid transparent polycarbonate, 100% transparent polycarbonate with indentations, or a hole clear through with a inserted glazing layer that sets in a thermal break. If integrated transparent polycarbonate or inserted transparent glazing is in the view through areas it serves as an IGU cavity dividing layer. This view through area may be fully integrated polycarbonate, or glazing layer inserted into a thermal break, serving to divide the air or gas space in a IGU cavity. This dividing layer in view through significantly reduces energy transfer that would otherwise exist due to convection. Convection is well established as the transmission of heat through air or gas by the circulation of currents; the vertical movement of heat especially by updrafts and downdrafts in a cavity between the two layers of glazing making up an IGU. A thermal break is added as an innovative separate component used in the notch that separates the polycarbonate vessel from the inserted view through glazing layer. Without this thermal break between the gel insulated part of the vessel and the vessels view through area dividing layer direct conduction would reduce the inventions ability to further minimize heat transfer. The thermal break serves to further reduce heat transfer and increase overall thermal performance. Thermal breaks are used throughout the invention that are constructed of a less conductive material such as structural foam or other suitable low conductive material, or other suitable technologies that may in the future be made available. Additionally, the polycarbonate vessel serving as a IGU insert can be manufactured to have a plurality of holes distributed throughout its surface leading into the cavities. The plurality of holes is sealed using vessel films to ensure the insulating gels are securely held inside the plurality of cavities while reducing heat circulation for reduced heat transfer. The plurality of holes serves to reduce the amount of polycarbonate used for the vessel and also reduce the surface area that can be contacted by other materials. The holes reduced surface area therefore directly translates to less direct conduction of heat transfer that can travel through the otherwise continuous solid polycarbonate vessel. The holes though interior dividing walls are also laminated to limit convection. Existing prior art is not thermally broken in the transparent glazing itself only the frames that mount glazing at times are is. The invention can also be more easily side loaded with a gel insulating substance unlike the prior art that is loaded through edges only. These technical features of the invention allow for choosing the best element from said set of alternative glazing benefits for maximizing overall function by systematically choosing the values of necessary variables that are currently and collectively unavailable in the glazing industry. The invention allows optimization techniques for finding the best available values of glazing's objective function, including a variety of different types of objective functions.
Recently, the thermal insulating properties of Aerogel have been uncovered. Aerogel was discovered in 1931 by Samuel Stephen Kistler. Since then, aerogel has constantly been researched and improved upon. Aerogels have now been applied to the window industry to product highly energy efficient windows. In the place of gases for the insulated glazing unit, Aerogels have been sealed within the window. However, even though Aerogel is translucent, it is not transparent. This property of Aerogel prevents the user from being able to see through a window long-term as clearly if it was glazing made of glass. Aerogel has also been applied to polycarbonate vessels for day-lighting windows. However, this application of aerogel has still yet to allow users to see through the windows.
New wall constructions are required by USA building codes to be up to R-19 value and ceilings are required to be up to R-42. R-values are a measure of thermal resistance used in building and construction. Traditional double pane windows with high visible glass currently on the market, on average, only have an R-value of 3. The present invention will be a gel insulated glazing unit that will be highly insulating while adding value though additional options such as geometric view through design possibilities over traditional windows offered on the market today.
The present invention is an insulated glazing unit which utilizes Aerogel particles sealed in a vessel as well as insulating gases to minimize the transfer of heat across a IGU window system. The aerogel filled vessel can be arranged in different patterns within a IGU cavity. Aerogel is a translucent material but not transparent, therefore the present invention contains the aerogel in a vessel to be arranged in a way where users can still look through a window while giving the window an aesthetically pleasing appearance. In addition, the vessel can be customized to control the direction the viewers from inside and outside can see through the window system. The ability of the present invention to control the range and direction of vision collectively makes a corrective lens insert for the IGU window system. The aerogel also has exceptional insulating properties which will aid the present invention to minimize heat transfer across the window. The invention, an optimizable view through gel enhanced IGU lenses system, is a insulating lenses system which allows light to traverses through and/or refract can be used for the optimization of these multiple following benefits: provides engineers the benefit of optimally manipulating the performance of the IGU window system in regards to not only heat transfer, but also soundproofing, light diffusion, light penetration, light density, ultraviolet (UV) light filtration, light distribution, light glare, security, privacy, solar rays, user viewing direction, and range that windows can be viewed into and out through. This view through areas can be 100% solid transparent polycarbonate, 100% transparent polycarbonate with indentations or holes clear through having sidewalls. Fully integrated polycarbonate view through areas having indentations or inserted glazing in view through areas serves as an IGU cavity dividing layer. The view through areas having a fully integrated polycarbonate layer serves to divide, or transparent glazing layer inserted into a thermal break, the air or gas space in a IGU cavity. This dividing glazing layer provides a view though areas while reducing energy transfer that would otherwise exist due to convection. Convection is well established as the transmission of heat in air or gas by the circulation of currents. This is especially true for vertical movement of heat by updrafts and downdrafts within the cavity between the two layers of glazing making up an IGU. The thermal break is a separate component used in the notch that separates the polycarbonate gel insulated vessel area from the inserted view through glazing layer. Without the thermal break, direct conduction would undermine the inventions ability to even further minimize heat transfer. The thermal break serves to reduce heat transfer through conduction and increase overall thermal performance. The thermal break is constructed of a less-conductive material such as structural foam or other suitable low conductive material, or other suitable technologies that may in the future be made available. In addition to the thermal break, the vessel may be manufactured to have a plurality of holes. The plurality of holes is sealed using vessel films to keep the gel insulating element secure within the plurality of cavities. Interior partitions also have holes and are laminated to limit air flow through these thermal breaking holes. The plurality of holes serves to reduce the amount of polycarbonate used for the vessel and also reduce the surface area that can be contacted by other materials. The reduced surface area directly translates to less direct conduction of heat transfer that can travel through the polycarbonate vessel.
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention. Although suitable materials are specified for the invention all other suitable materials, to include emerging technologies that may be made commercially available in the future, may also be used.
Thermal insulating windows have become a product that is able to help families, buildings, subways, cruise ships and other conditioned living spaces significantly save on energy costs. Many types of windows have been developed trying to maximize insulation and minimize heat transfer. The present invention is an Insulating Glass Unit (IGU) vessel that serves as the IGU cavity insert. The invention utilizes a highly versatile IGU cavity insert that is nanotechnology gel insulation enhanced, UV stable transparent polycarbonate vessel. The IGU insert has view through areas that may be one or more of the following; 100% solid polycarbonate, 100% polycarbonate with indentations, a hole having walls through the vessel insert, a hole having walls through the insulating insert with a inserted layer of glazing. All of these areas that are not obscured by the insulating gel are for viewing through. It is the objective of the present invention to be optimized in regard to insulating, soundproofing, light diffusion, light penetration, light density, ultraviolet (UV) light filtration, light distribution, light glare, security, privacy, solar rays, user viewing direction, and range that windows can be viewed into and out through.

Fully integrated polycarbonate or inserted glazing in view through areas serves as a dividing layer 223. The view through areas having a fully integrated polycarbonate layer serves to divide, or glazing layer inserted into a thermal break, the air or gas space in a IGU cavity. This dividing glazing layer provides a view though area significantly reducing energy transfer that would otherwise exist due to convection. Convection is well established as the transmission of heat in air or gas by the circulation of currents. This is especially true for vertical movement of heat by updrafts and downdrafts within the cavity between the two layers of glazing making up an IGU. The thermal break is a separate component used in the notch that separates the polycarbonate insulating insert from the inserted view through glazing layer. Without the thermal break, direct conduction would undermine the inventions ability to even further minimize heat transfer. The thermal break serves to further reduce heat transfer and increase overall thermal performance. The thermal break is constructed of a less-conductive material such as structural foam or other suitable low conductive material, or other suitable technologies that may in the future be made available. This same type of structural foam is commonly used, although utilized much differently, in different configurations and different purpose as an Insulated Glass unit perimeter edge spacer. The structural foam is also commercially available from Edgetech and Dow Corning. Dow adhesive designed specifically for the structural foam shall be applied to the silicone structural foam in order to effectively bond the film having the highly reflective mirror like surface. The mirror like surface shall serve to reflect the image of the polycarbonate and, or suitable gel insulating substance for esthetic purposes and, or, reflect radiant heat. The structural foam thermal break serving as a spacer is preferably a thermoset silicone foam matrix. The thermoset polymer thermal break serving as the spacer is set to size and shape during heat curing while factoring in the film thickness as a final laminate in order to precision fit the contour of the receiving contour in the polycarbonate receiver. The thermal breaking spacer retains its flexibility and possesses a low compression set. The structural foam is bonded in place with a suitable high-performance acrylic adhesive. Silicone thermal breaking spacers used in the fenestration industry are known to resist heat flow up over 900 times more than aluminum. The insulating insert may be manufactured to have a plurality of holes. The plurality of holes is sealed using transparent vessel adhesive and vessel films to keep the gel insulating element 6 secure within the plurality of cavities 4. The plurality of holes serves to reduce the amount of polycarbonate used for the insulating insert and also reduce the surface area that can be contacted by other materials. The reduced surface area directly translates to less direct conduction of heat transfer that can travel through the polycarbonate insulating insert. The present invention is a type of window system insert that makes use of insulating materials with exceptional insulating properties to minimize heat transfer across the window. This invention is able to effectively insulate and reduce heat transfer while allowing users to be able to see through the window without being hindered by the insulating material. The insert is a two part insert that comprises of a vessel cover 1 and a vessel base 2. In addition to the vessel base 2 and the vessel cover 1 the present invention comprises of a plurality of cavities 4, a plurality of end openings 5, an insulating element 6, a vessel coating 7, an interior vessel film 8, a film adhesive 9, an end opening sealing film 10, and a sealing adhesive 20. The vessel cover 1 and the vessel base 2 together form the main body of the present invention. In the preferred embodiment of the present invention, these polycarbonates are to be transparent and manufactured from Lexan polycarbonate. Other suitable transparent polycarbonates such as Calibre from Dow Chemicals Company, Iupilon from Mitsubishi Engineering Plastic Corporations, Makrolife from Arla Plast, Makrolon from Bayer Material Science Group, Panlite from Teijin Chemical Limited, Tarflon from Idemitsu Kosan Co., and LBE from Rodeca may also be used. No matter what material is used, it is important that the material be clear enough as to allow the desired amount of natural light through the window. The polycarbonate materials of the vessel base 2 and the vessel base 2 is covered with the vessel coating 7 or can be manufactured to be UV stabilized and UV deflective, preventing it from being damaged from UV rays and allowing it to reflect the destructive UV rays from its direction of origin. Being UV stabilized also prevents the material from yellowing. The vessel coating 7 provides the vessel base 2 and the vessel cover 1 with the property of being UV stable for long lasting clarity.

The plurality cover holes and the plurality of base holes 23 that are evenly distributed on all the surfaces of the insulating insert serve to reduce the amount of solid polycarbonate surfaces that can directly conduct heat energy. The edges of the view through components 22 can also be manufactured according to a user's environment and preferences. For example, the sun is higher, hotter and has more damaging UV during the summer and will provide more light, heat and UV than desired, so the edges can be angled to manage the sun's rays and, or, light. However, with a lower sun during the winter and a lower sun later in the day during the summer, so the angles of the edges may be made to allow the optimal amount of light in while insulating. Many different possible geometric shapes can exist for the present invention.
The system can be having different configurations to effectively manage the sun's rays and, or, light. This can be done by specifying angles for the view through components 22 edges. The types of configuration used can effectively minimize three types of heat transfers including radiation, conduction, and convection. The gel insulating element 6 sealed within the vessels are excellent insulators which can reduce radiant heat as well as any conduction of heat. When used with a sealed insulating glazing unit with the use of argon gas within the sealed unit, due to the gas' heavier and thicker properties, convection is limited through the unit as well. The present invention serving as a window insert, can provide a double pane insulated glazing unit (IGU) with the properties of a triple pane IGU. By inserting the present invention into the sealed cavity of an IGU, the present invention is able to bisect the space inside the IGU. The bisection of the sealed space creates two separate spaces. The division of the sealed space significantly reduce energy transfer that would, although be reduced by the gas, still exist due to convection. Convection is well established as the transmission of heat through the current circulation of air or gas inside the IGU cavity. Such current circulation includes vertical movement of heat, especially by updrafts and downdrafts in an IGU cavity between the two layers of glazing. The thermal break components 253 in the present invention are used in the present invention that separates the multiple components that are in direct connection. Without the thermal breaking components, direct conduction would undermine the invention's ability to even further minimize heat transfer. The thermal breaking components serves to reduce heat transfer and increase overall thermal performance. The thermal break is constructed of a less-conductive material such as structural foam or other suitable low conductive material or other suitable technologies that may in the future be made available. The top and bottom sides of the vessel view through components 22 will have a steeper angle as to block solar heat and light when the sun is high and hot with maximum UV. For users in colder climates, a configuration of the system may include clear areas for more light to enter. Edges can be angled to allow much larger field of view out the system. Also a vessel filled with suitable gel insulation will insulate to keep heat inside of building.
Some factors that can help users determine what configuration of the present invention they would like include the following:
This system allows for users to see through the present invention while being efficient in minimizing the heat transfer across the window. All of the components of the present invention contribute in excellent insulating properties by reducing solar heat gain and significantly reducing transmittance of the destructive ultraviolet rays. The areas on the system which are covered by suitable gel insulation in combination with the gas sealed within an IGU together enhance the insulation for stopping heat transfer from any conduction through a window. This will help leakage of heat from the building during the winters as well as prevent heat from entering building during the summers. The films used in the present invention help manage the harmful rays such as UV that are projected from the sun to protect the users and objects within a room from damage. Any number of different shapes and sizes can be used for the present invention for different designs. The gel insulated vessel areas between arrangements of view through components 22 allow users to see through the optically clear glazing panes of an IGU. In addition, the angled edges of the view through component can allow users to have a larger field of vision while also limiting the heat transferring through.
The ability of this system to control the direction that viewers can see through the system inside and outside make this system a corrective lens as shown in
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed
