CVD (chemical vapor deposition) Ultra High Performance Low-E is a highly transparent “On Line” coating glass. CVD Ultra High Performance glass has a durable pyrolytic surface. This CVD Ultra High Performance Low-E glass is easily fabricated to value-added secondary glass products such as insulating glass units (IGU), tempered glass and laminated glass.

  • Topline Ultra High Performance Low-E is a low solar heat gain and low-emissivity glass. During summer, it blocks solar energy and during winter, Ultra High Performance Low-E could maintain the heat inside the building.
  • Reduces heat gain, with an I.G. solar heat gain coefficient (SHGC) of only 0.43, compared to SHGC of 0.70 for clear float and 0.61 for Low-E glass.
  • Good light transmittance for Ultra High Performance Low-E. When glazed on the #2 surface in monolithic, Topline Ultra High Performance Low-E glass provides 60% visible light transmittance.
  • Low exterior reflectance makes Topline Ultra High Performance Low-E glass ideal for use where high reflectance is prohibited or undesirable.
  • As Topline Ultra High Performance Low-E coating is quite durable, the glass can be stored for long periods. You can handle and cut it in the same way as with ordinary float glass.
  • Since we can deliver the glass in stock sheet size, keeping it in stock enables you to reduce lead times.
  • As this glass is unaffected by changes in temperature, heat treatment such as bending, tempering and laminating is possible.
  • Combining the glass in insulating glass units enables greater thermal insulation performance. Furthermore, edge deletion is not required, so no extra work is needed.

On-line CVD method is to form a metal-oxide (SnO2) coating during the float glass production. Molten glass is extruded onto the flat liquid surface of molten tin in a float bath and molded horizontally. Raw material gas is introduced onto the surface of the glass, which is about 650°C, and a coating forms from the chemical reaction of the gas with the heat energy of the glass. Thus, when the glass is annealed and cut, it already has a homogeneous coating on its surface.


  • Store the glass in a dry place without direct sunlight. To avoid breakage, store it vertically and used cushioning materials.
  • Inspect the glass immediately upon receipt. Do not use it if there is any breakage or scratch on it.
  • We are not responsible for any glass breakage, scratches, contamination and other defects resulting from improper use or applications, misuse, rough handling or any reason not related to defects in material or workmanship of the glass.
