Question regarding a glass shield for heat and debris protection:

Glass Detective,

We have a piece of equipment with a window using four (4) glazing panes. two(2) panes are the inner operator side consists of a lexan type product made by Bayer. The other (2) two consists of one pane ceram type glass to withstand heat to 1300F the other is a tempered glass used for impact resistance. Is there a special sequence for the placement of the special glass in order to acheive protection from high heat and protection of explosion from flying debris (metal)?

Answer to question regarding a glass shield for heat and debris protection:


Thank you for contacting the Glass Detective with your request. Let me first apologize though for taking a few extra days to get back to you. You see, even the Glass Detective has to have a few days off every now and then and I combined the 4th of July holiday with a couple of vacation days and got away for a while. So thank you for your patience.

As to your question about the order of installation for the glass being used on one of your pieces of equipment, here are my thoughts:

I am 95% confident that I can tell you what the proper order of installation (sequencing) would be for your equipment because I have worked around enough processing equipment/machinery to understand the purpose of the different types of glazing materials you are working with. However, this is not a situation where you want to have 95% assurance that you are getting it right. The only way to know that you have it 100% right is to either talk to the equipment manufacturer to find out their recommendations/requirements or find the equipment manual that should have come with the device.

Either approach should give you the answer you need and we will both sleep better at night. In the modern “internet world” you should be able to get an answer pretty quickly. I hope this is of some help and I wish you well with your project.
