Low e argon unit failures

can anyone give me info on the low e argon filled units and why they go bad?my house is six years old and 11 out of 18 windows are bad and one even blew up. i was told about this problem by the glass store but i need more info on it.the company that makes them is saying they have never heard of this problem and that it is my fault.all the windows that r bad get full sunlight all the time and the good ones only get shade .so any info on the problem would be a big help thank you all
