Dear All
I have installed a laminated glass floor - made out of three glass panes of 15mm each. On installation there were no defect. After 4 months air bubble like defects started developing between the layers of glass, at different levels - that is some between the upper and middle layer - others between the middle and lower layer.
What could be the reason for this?
Thanks in advance
Dear Kenneth,
I am Andy from Shenzhen Dragon Glass. We are professional glass manufactuere since 1994. And I worked as glass engineer for over 10 years.
Very sorry to hear that you have quality issue with your laminated glass floor. For the bubbles occuring it is actually a kind of delamination. That is because during the production of tempering, the deformation of glass is not uniform.
When two pieces of glass distortion after tempering is no the same. Sometimes some manufacturers will use a clamp to clap the glass together and then place it into the lamination oven.
After production is finished, there will be no apparently flaws in the lamination glass floors. Only after several months ot years, then the glass will start delamination.
To solve this quality problem, there will be two ways:
1) To choose a good quality control glass manufacturer who can control the tempering stress with minimum distortion.
2) To use thicker PVB interlayer to bond the glass together.
3) Use a metal frame to clame the glass floor when you are doing installation.
