PPG Glass Certified Fabricator Audit

PPG engineers conduct an annual Certified Fabricator audit at each participating member location. This comprehensive, multiple-day audit addresses the fabricator's equipment as well as their documented processing procedures. The following is a list of major glass fabrication processes PPG inspects:

Process	Key PPG Focus	Benefit
Storage	Check that glass is properly stored	Optimal surface quality obtained
Handling	Check for proper surface and edge conditions	Reduced handling defects
Cutting	Check for proper cutting pressure	Optimal edge quality obtained
Seaming	Check for optimal edge condition	Reduced potential of stress fractures
Edge Deletion	Check that coating is safely and thoroughly deleted Optimal sealant adhesion	Optimal sealant adhesion
Washing	Check for surface cleanliness	Optimal aesthetics and sealant adhesion
Tempering	Check that glass is heat-treated to appropriate standards	Desirable performance obtained
Insulating Glass Assembly	Check for proper sealant coverage and adhesion	Improved insulating glass units life
Packaging & Shipping	Check for proper glass packaging and transportation	Minimized transit damage
