That explains a lot about the composition of fire-rated glazing. I don't know what the treatment is that's applied to "Fire-Lite" or other rated glass but the knock on those products is that they are exorbitantly expensive. It's not as if you can order up pieces of it - you have to purchase the entire assembly, including and especially the frame. If you've ever seen this stuff up close, especially if you've seen a section cut at trade show, the frames are not only really over-built compared to conventional windows, but instead of simple gaskets or weather seals there is a bead of fire caulk around the glazing on both sides. The frame and sealant are where the bid money goes, along with the costs of testing and listing of course.

And that covers our ifs, ands or butts. But the truth is, there still is the remote (and assumable) chance that in an unsprinklered building where we use the window sprinkler to assist us in achieving a wall rating... e.g. in the case of a 2 story wall uninterrupted by a floor that has glass comprising only the bottom story... there is a real possibility that the window sprinkler system will not prevent window breakage from a fire. Then the next question is, for the engineer or architect at least, so what if the wall breaks? It is a big what if, if the fire exposes a nursery school, or retirement home, or similar life safety challenge, but in many occupancies, everyone of reasonable mobility abilities will still exit safely. Property protection is another mention. scot deal excelsior fire protection _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [EMAIL PROTECTED] To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field) __________ Information from ESET NOD32 Antivirus, version of virus signature database 3493 (20081003) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature database 3493 (20081003) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [EMAIL PROTECTED] To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field)
