Glass Splashbacks

I write in reply to all questions on Glass Splashbacks.I am a cabinetmaker/shopfitter by trade.I Own Graphic Glazing Glass Splashbacks in Sydney.I pioneered this industry 6 years ago and currently my company measure,produce and install 50 Splashbacks a week.I Would like to reply to some comments I read in some articles.
You must toughen Glass behind cook tops for heat.You cant just paint your own glass if you want the coating to be permanent.The average price for a Glass Splashback is aruond $900,which includes measure,manufacture and installation.This is cheaper than granite,stone and s/steel.All joints are silicone sealed.All edges are polished.
My guys have pulled out and replaced so many jobs that were 'clean cut',paint falling off,silicone bleeding through the paint,10mm joints,etc...
If I can help anyone out with any information,please let me know.
