Once all of the facts regarding the issue of scratched glass and its causes are out in the open, it is important to address the next steps in the resolution of the problem.
The key to solving this issue lies in education of builders, window cleaners, and the construction industry as a whole. All parties need to be educated on the importance of high-quality tempered glass.
Builders must know exactly what they are buying and refuse to accept any defective tempered glass that can be scratched when cleaned, either by their window cleaner or a future homeowner. After builders know the difference between high and low-quality tempered glass, most of them will demand only quality tempered glass that can be cleaned by standard construction window cleaning techniques.
Builders would never accept a window from their supplier covered with paint or plaster, so why would they accept defective tempered glass covered with fabricating debris that scratches when cleaned? The only acceptable answer is because they didn't know the cause of the problem. This reason is no longer acceptable, as the means and the information is out there for any builder to educate themselves on the facts.
Construction window cleaners must also educate themselves about the issues. They must be aware of the risk involved in using any scrapers to clean construction debris off defective tempered glass. They should be educated on the causes of this tempering defect and be prepared to advise their builder on the risks of buying such glass. Window cleaners should also notify their builders that all windows should be protected during construction and that any unprotected windows will require the use of scrapers to remove construction debris.
The construction industry as a whole must be aware of the differences in surface quality of tempered glass. They must also acknowlege the importance of protecting all windows during construction, and ensure that proper steps are taken to meet this end. And finally, they must not overlook the importance of using skilled construction window cleaners who are trained to clean windows in a construction environment.
