Low-E Glass Tempering

Mr Jorma Vitkala

It is problematic to heat up Low-E glass in a traditional radiation type furnace, because the glass will bend during the heating cycle which leads to different problems such as viscoelastic changes, coating distortion, surface defects, uneven bending etc.

If we add forced convection to radiation furnaces it becomes possible to temper Low-E glass with the current manufacturing methods on the market. However, the emissivity requirements will be lowered in the future and for this reason we need new manufacturing solutions. One such solution is the use of convection in tempering furnaces.

This paper will give you an idea about the latest developments and test results in this field.
