Heat Treating: Where the annealed glass is subjected to a special heat treatment in which it is heated to about 680°C and afterwards cooled.
Chemical Strengthening: The glass is covered by a chemical solution which produces a higher mechanical resistance. Chemically - strengthened glass has similar…

Decibel (dB) - a unit of power loss or attenuation used in EMI/RFI shielding:
1 decibel = 10 log (Power in/Power out).
A 3dB loss is a fifty percent power reduction.
