Vacuum Insulated Glass (VIG) Technology

� VIG Structure

• There are spacers to form a gap within two

glass panes. Using the frit on glass edges to

make a frame to enclose the space.

Inserting a tube connected to this space for

degassing. After degassing and sealing this

tube, the glass is formed as a VIG.

• VIG has vacuum layer within it, so it has

great insulation for both heat and sound.

� VIG can be adhered to Low-E films,

UV filters, tempered glass, PV cells

and so on, for various applications.Glass(front)

TECONano’s VIG – Unique Features

Product FeaturesTeconano(Taiwan)

Substrate•Our substrates are identical in size. It’s easy for fitting in frames.

•3rd party’s substrates are inconsistent.

Spacer

•Both of spacer and substrate are the same glass material. The adhesion is strong to prevent spacers from falling off.

•The mountain shape spacer makes less area and free contact with the other glass pane. It makes high thermal resistance and prevents strain broken.

•3rd party’s spacers are easy to fall off. And the shape is not good for heat insulation.

Degas tube

•Our flat pane sealing technology installs degassing tube on side, and the tube can be hidden in window frame.

•3rd party’s degassing tube is installed in the visible area and sticks out on the glass pane surface. It’s easy to be broken during setting and processing.

TECONano’s current development

� Tubeless degassing technology

• To fulfill the requirements from renovation

market, TECONano is developing an

innovative tubeless degassing technology to

achieve the thickness target, 6mm, for VIG.

• Without sticking out degassing tube, the

surface of the VIG pane is flat that

improves the yield of VIG process, the

efficiency of packing and shipping, and the

aesthetic of VIG.


Certification for Thermal Insulation

� National Standards of P. R. China, GB/T 8484-2008

� Graduation and test method for thermal insulating properties of doors and windows

� In 2014, TG TECO VIG’s VIG (CL-TDE78#2 + VI + CL), (8+0.2V+8)mm, U value has reached

0.61W/m2K

Test Result: U=0.7 W/(m2K)(4L+12A+4C+0.2mmV+4L)

Grade 10 Requirement: U<1.1 W/(m2K) (Highest Level)

Sound Insulation

� The vacuum space of VIG can block the sound transmission and reach Sound Transmission Class by 39dB. The sound insulation of VIG is better than that of insulated glass.
