Fields - "Tempered Glass Defects"
IWCA
official position on scrapers and
fabricating debris on tempered glass.
This website focuses on one issue - excessive abrasive fabricating debris on some uncoated tempered glass surfaces. The mission here is to provide credible information, and to increase demand for quality tempered glass surfaces - without fabricating debris. 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 cleaning scraper. Check out our Fabricating Debris Documents & Links Page for links to glass industry magazine articles that address the issue of equipment maintenance. It is clear from reading these articles that equipment maintenance DOES have an effect on the surface quality of tempered glass. Builders, architects and remodelers who understand that temperers are able to minimize fabricating debris issues can specify tempered glass surfaces without excessive fabricating debris - surfaces that can be cleaned efficiently with standard methods, not only after construction, but throughout the life of the home or building. |
Scrapers
do not scratch glass - Clearly,
these (magnified) tempered glass scratches did not occur until a scraper encountered a surface
defect. "Scrapers

keep adding data, publications, letters, photographs, images,
etc.
