Having a hybrid vacuum insulating glass system means you will be able to reduce the amount of heat you lose from the space that you have built. This is because you will be able to have low U-values, and the emissivity coatings that are used on the interior surface of the glass will also be able to help.
Low Emissivity Coatings
Spectrally selective glass is a type of glass that has lower reflectivity than conventional glass, providing a range of visible light transmission between 40 and 70 percent. This allows for more natural lighting and greater transparency. It can also offer a low U-factor and solar heat gain coefficient.
There are two main production methods for low emissivity glass. They include the pyrolytic process and the MSVD process. The pyrolytic process produces stock sheets of different sizes. It is a very popular process in the early 1970s. It uses a pyrolytic coating that is applied to the ribbon of glass while it is on a float line. This “fuses” the coating to the glass surface, creating a durable bond.
Low e glass is a type of thin film that is applied to the surface of a glass panel to reduce the amount of radiant heat loss through the glass. The coating is thin enough to allow the sun’s short wave infrared energy to pass through the glass, while reflecting the long wave infrared and far infrared radiation directly back into the room.
Mechanical Loads On The VGU
Deflections and stress-pressure curves were measured on glass panels of a novel hybrid vacuum insulating glass system unit. The stress-pressure curves show the magnitude of the stresses developed in each panel. These stresses result from thermal load and temperature difference. The maximum in-plane principal stress can be calculated by substituting. Then the deflection of the upper and lower glass panels can be computed. This is done for both toughened and non-toughened glass panes.
The tensile stress parallel to the edge of the unit is three times greater than the isotropic stress away from the edge. This is the main stress field of interest for potential failure of the glass sheets. The temperature difference is due to the hot and cold environments. This difference causes bending of the glass panes. In addition, the bending of the panes induces additional stresses in the glass sheet. The effect is largely dependent on the thickness of the glass.
Heat Energy Loss Between The Indoor Space And The Indoor Glass Surface
Using the right glass for your office is a great way to cut your energy bills. The latest glass technology is all about temperature control, UV protection and anti-static. Some manufacturers even offer incentives to switch over to their product line. The benefits can be as simple as a cooler indoor climate. The best part is the savings aren’t hard to come by. Getting the right glass for your office is the first step to energy efficiency. You can find out all of this by requesting an informational quote from one of the many glass dealers in your area. The information is free and the rewards are well worth the effort. This is especially true if you are building an office from the ground up.
Design Conditions For A Hybrid Vacuum Insulating Glass System
Using a novel hybrid vig performance, mechanical loads can be minimized on triple glazing. This system encloses a vacuum insulating glass unit within two glass panes. The VGU is separated by a spacer, which provides a thermal bridge between the two glass panels. A well-defined spacer size and geometry is important to achieve a consistent gap between the panes. The spacer can be processed on conventional bending equipment, ensuring that it provides the same process ability benefits as a metal box spacer.
The spacer has a diameter of 0.3 to 0.5 mm. It is made from a high strength metal, such as stainless steel, for improved durability. The spacer is inserted between the top and bottom panes of the VGU. It is a critical component of the VIG product. The spacer must be defined in its geometry, be strong enough to hold the weight of the upper panel, and must have a defined spacing between the panes.
So, hybrid is a high performance vacuum insulating glass system that provides a unique alternative to gas filled glazed IGU. It is designed to provide high thermal efficiency and noise abatement. It is a high-performance hybrid unit that integrates vacuum glass, an interior lite and a high performance low e coating. It is a practical size that can be installed into existing frames in minutes.
