Triple IG Unit Spacer Alignment Tolerance

I am in search of a document, preferably ASTM or similar, that outlines:

  • the tolerances for IG units in regards to spacer alignment, in terms of the straightness of the spacer along any given length for foam spacers, and
  • the parallel alignment of spacers in triple IG units

If anyone knows where I can find this information, I have about exhausted my search online.


Defects between layers of laminated glass floor

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

How to obtain consistent results from our tempering line?

You're thinking that its hard to get help with assignment predictable outcomes from your treating line. It appears that the cooling spouts are somewhat unpredictable in the range from the glass. Your Chinese producer has prompted you to utilize the heater persistently to get a steady outcome.

Laminated Glass Defect: Bubbles/Blur at Perimeter

I have a residential project where we installed casement windows and door glass panel to overlook at the great panoramic ocean view.

The laminated glass on the casement windows and doors recently began showing strange blur/bubbles around the edges of the glass (Pictures Available of Condition).

Does the above condition have a quick fix (home remedy) that can be used? Replacing the laminated glass would be very costly given the amount of windows at the residence. This condition can be observed on 90% of the windows.
