Ira Posted May 15, 2012 Report Share Posted May 15, 2012 Seems to agree with the FNZAS class thickness calculator, so i'd say yes. http://www.fnzas.org.nz/?page_id=1635 Quote Link to comment Share on other sites More sharing options...
henward Posted May 15, 2012 Author Report Share Posted May 15, 2012 according to that website, 2 to 3.9 is 'safe' 4 plus is VERY SAFE so.... would you say a safety factor of 2.5 is good? or what how does it work? Quote Link to comment Share on other sites More sharing options...

redracer77 Posted May 15, 2012 Report Share Posted May 15, 2012 Sorry to hijack, Does the safety factor change for low iron/starfire glass? Does low iron mean weaker glass? Quote Link to comment Share on other sites More sharing options...
Warren Posted May 26, 2012 Report Share Posted May 26, 2012 My understanding is it changes very little. You can be sure by finding the datasheet for the different types of glass and comparing the tensile strength. They should only be a very small percent different if any.
