THERMO-BELT Ultra S®
Solar Control Insulating Glass
Regulation of Solar Heat Penetration
Solar control technology is really valuable, especially for hot and sunny places. The advantage of this “invention” is that in contrast to shading systems, solar control glass allows natural light to enter freely into the building, keeping the solar radiation outside. It can be used widely for façade glazing, but also for windows glazing, curtain walling, bolted glass assemblies and glass greenhouse roofs. Moreover, it can be combined with almost all types of glass, such as UV-LAM®, ECHO-LAM®, CHROMA-LAM®, ASPIS-LAM®, G-GUARD® and HSG-GUARD®. Here is a list of benefits that solar control technology can provide you with:
Superior comfort: it regulates the amount of solar heat that moves through windows, resulting in cool and comfortable interiors.
- Energy saving: it decreases the need for expensive air-conditioning and artificial lighting.
- Enhanced feeling of privacy: solar control glass hinders inward visibility.
- Design: it comes in various colors adding visual appeal to buildings.
Not every type of solar control glass is suitable for every purpose. Color neutrality or high reflection may have various functional aspects, so the extensive range of solar control glass offers a wide spectrum of design options.
Yalodomi’s THERMOBELT Ultra S® is a specific range of high-end coated solar control glass mainly for residence applications. They offer a balanced ratio of selectivity, meaning a low g-value and a light transmission as high as possible.
KEY POINTS FOR THERMOBELT ULTRA S®:
- It is a passive energy saving component.
- High quality solar control glass can protect the residences from reaching high temperature due to sun rays.
- You can control the light in the room, by using different colors on the glass.
- Solar control glass is the most effective alternative among all the energy saving alternatives, with no maintenance costs.
- You can easily replace the glass in existing constructions.
THERMOBELT Ultra S® has the following technical specifications:
Light transmission (Tv) is the measurement of the ratio of the visible sunlight that is transmitted directly through glazing in the visible wavelength (380nm to 780nm). Light transmission ratio is depended on the glass thickness. A 4mm float glass has 92% light transmittance and THERMOBELT Ultra S® | Solar, 80%.
Light reflection (Rv) is the measurement of the ratio of the visible sunlight that is reflected on the glass surface in the visible wavelength (380nm to 780nm).
Direct radiation transmission ratio (Te) is the measurement of the ratio of the sunlight that is transmitted directly through glazing in the range of wavelengths from 300nm to 2500nm.
Direct radiation reflection ratio (Re) is the measurement of the ratio of the directly reflected sunlight in the range of wavelengths from 300nm to 2500nm.
Direct radiation absorption ratio (Ae) is the measurement of the ratio of the directly absorbed sunlight in the range of wavelengths from 300nm to 2500nm. Some of the absorbed energy is discharged outwardly and some inwardly. The inward radiation is called secondary heat transfer factor Qi.
COLOR Rendering Index (Ra) describes the perception of color recognition of objects viewed through an insulating unit. THERMOBELT Ultra S® | Solar 60/28 has a refractive index of 94, meaning that the objects through the glass pane can be seen with their natural color.
Shading Coefficient (SC), is the average shading coefficient of solar energy, when it is compared with an uncoated double insulating glass unit. The use of this coefficient is crucial for the cooling load calculation of a building.
Total energy transmittance ratio (g-value) is the total of the direct radiation transmission ratio (Te) and the secondary heat transfer factor. A low g-value involves a reduced light transmission ratio.
Selectivity (S) is the ratio of light transmission (Tv) to the total energy transmittance ratio (gvalue) and it is the measurement of the efficiency of the glass. The currently available maximum selectivity is achieved with THERMOBELT Ultra S® | Solar 60/28.
