Low-e coating glass making process
- Oct 06, 2018 -

There are two primary production methods for low-e coating glass:


  1.  pyrolytic, or “hard coat”, In the pyrolytic process, which became common in the early 1970’s, the coating is applied to the glass ribbon while it is being produced on the float line. The coating then “fuses” to the hot glass surface, creating a strong bond that is very durable for glass processing during fabrication. Finally, the glass is cut into stock sheets of various sizes for shipment to fabricators. Mainly for passive low-e coating glass.

  2. Magnetron Sputter Vacuum Deposition (MSVD), or “soft coat”.  In the MSVD process, introduced in the 1980’s and continually refined in recent decades, the coating is applied off-line to pre-cut glass in a vacuum chambers at room temperature. Mainly for solar control low-e glass.
