Top 3 Guangdong double glazed glass suppliers

1, What is dgu glass?

Double insulated glass(dgu glass or igu glass) is also called double glazed glass, it combines two pieces of float glass or tempered glass or coated glass together with an aluminum spacer in between and sealed with butyl and structural sealant. In purpose to achieve extra functions like soundproofing or thermal isolation.

Sometimes argon gas will be filled into the space between the two panels to enhance the thermal performance, thus making the insulated glass U-value much lower(which means less heat transferring). Insulated glazing glass is considered as energy-saving glass, especially when using Low-E coating glass as a part of it.

Ceramic frit glass or digital printing glass is also available for insulated glass to make the decoration much more colorful.

2, How to produce dgu glass?

To ensure dgu glass strength and safety function, usually tempering process is acquired when processing the glass panels. After glass tempering, pair the two pieces of glass panels in the auto insulating production line. During the transferring glass, workers will make the aluminum frame and sealed with first butyl sealant and adhere to the glass, combining the two panels manually first and make sure there is no overlap(will double-check by the insulating line), after the pre-press processing, the glass will be transferred to the second sealant processing, where the structural sealant is sealed by the robot.

We use the world most advanced Bystronic & Lisec insulating line to make sure the insulating quality is perfect without flaw. During each process, QC observers follow the quality system and make sure there are no quality issues.

3, How to distinguish the quality of dgu glass?

  1. Observe the surface of the dgu glass products make sure there are no chips, no scratches no bubbles or stones;
  2. Check the glass warp and distortion, good quality insulating glass should be size accurate and super flat surface, easy for installation;
  3. Check the spacer, see if the spacer is fully covered by the butyl sealant, it is the first insurance that the dgu glass has good performance;
  4. Check the structural sealant(on the edge of dgu glass) make sure the sealant is covered homogeneously and good.
