Members of the Glass Association of North America       ( GANA ) publish information relating to jobsite protection and cleaning of architectural glass products. In order to ensure long-term performance of the glass in a building, GANA encourages glazing contractors, general contractors, building management and owners to be aware of conditions that can damage glass and to follow the handling and cleaning guidelines provided by their glass producer and fabricator.

The glass industry takes extreme care to avoid glass scratches by protecting all glass surfaces during glass manufacturing and fabrication, as well as during all shipping and handling required to deliver the glass to the end user. A large percentage of damaged glass results from non-glass trades working near glass. This will include painters, spacklers, ironworkers, landscapers, carpenters and others who are part of the construction process. They may inadvertently lean against the glass, splash materials onto the glass and / or clean the glass incorrectly, any of which can permanently damage glass.

Builders have taken the hit for millions of dollars worth of damage to tempered glass. They may have blamed window cleaning practices for this damage, often without realizing that fabricating debris may have been the root cause, or without understanding how an uncoated tempered glass surface might have so much fabricating debris that it will scratch so easily.

The issue here is why some uncoated tempered glass   - but not all - may be so laden with abrasive fabricating debris that it will scratch when you clean it with a standard window cleaning scraper. Fabricating debris is an inherent problem with tempered glass, but clearly some temperers do a good job of minimizing it, while others do not.

A "perfect" surface is not necessary. What is needed is a surface that does not have so much fabricating debris that it will scratch when you clean it with a window scraper. for more information, visit
