What good is a waiver when glass manufactures put this kind of disclaimer on their material.
This is from Cardinal Glass:
WARNING: CARDINAL FG COMPANY AND ITS

OR OTHER INAPPROPRIATE CLEANING PROCEDURES
WILL SCRATCH GLASS, PARTICULARLY TEMPERED
GLASS OR HEAT-TREATED GLASS.
DISCLAIMER: CARDINAL FG COMPANY AND ITS AFFILIATES DO

Translation: âWe have your money. End of service. lul!â
But really, wouldnât a blade waiver still be applicable, if not even more substantial since the manufacturers themselves are saying, âthis will likely scratch if you use a blade.â
And, it also puts pressure on the contractors who install/work/paint around windows, by making them liable for us having to use blades and/or harsh chemicals on glass thatâs not made to sustain them. Am I wrong in that?
So, a blade waiver seems to still make sense, just in a âblame the person who got your glass so messed up in the first place that we have to clean it with these toolsâ kind of way.
Getting builders to make sure the glass is protected from the factory all through construction so we donât
have to use blades on crappy glass that the manufacturers wonât take responsibility for is the way to go.
That is one option for sure. But if I got a signed waiver, then I would be more
comfortable working on tempered glass, knowing that if it has fabricating debris
9 time out of 10 it will scratch.
its a finish product that has to be installed while the rest of the rough work is done, my opinion is it will always be an unwon struggle since its asking âroughâ mentalities and trades to behave as âfinishâ mentalities and trades, along with all the laborers and helpers that may not be aware of much, working on, near, around the windows as well
it will take a vigilant general contractor on everyone like glue from start to finish and some 10 mil covering from factory on the glass to get some success
but im sure its trickling down to some degree to the GCâs because of all the window mfr stickers and labels etc
its when you get a GC that put forth zero preventive effort, has a mess and then demands you use no razors etc is when there is really stupid situation one would probably be better served to stay clear of
there would probably be more success if GCâs couldnât find anyone in the first place to clean their neglected glass, but there will always be the unaware, uninformed or the new or the janitorial or do it all type companies that will give it a go with unfortunate consequences
So these manufactures cleaning guides finally made it to the USA.
Those have been here for close to a decade now, personally I donât do CCUs anymore because of no blades.
If a product has a waiver on it from a manufactures then a waiver from you attempting to circumvent the initial waiver is mute, in court the initial waiver will hold.
So what happens is at the point of the build when the windows are installed they call those guys out and they paint the windows with a peelable coating that prevents any damage to the surface then it is simply peeled off once construction is complete. Nowadays the most reputable builders will add this extra step to avoid having to replace glass.
Whereas you have not so reputable builders not even understand the difference between a builders clean and a final clean SMH⌠Pro tip final clean means all the building work has been complete and the windows have already received their builders clean.
GANA 01-0116 Non-Routine Post-Construction Cleaning & Restoration
It is from the early 2000âs I thinkâŚ.
I have put in bold some very interesting pointsâŚ.
It seems to me like GANA is saying that glass needs to be protected from the factory and if it isnât and gets construction debris on it, then go ahead and use a metal blade.
But then the manufacturers contradict that and put a disclaimer on their glass. What a freaking mess.
During all stages of construction the glass must be properly protected from construction debris such as cement, paint, varnish, adhesives and other construction material commonly found on job sites. (See the GANA/IWCA Bulletin TD 03-1003 (2010 Edition) Construction Site Protection and Maintenance of Architectural Glass) . Extended construction schedules may create the need for multiple cleanings to avoid the accumulation of significant amounts of soil and debris, and to avoid potential damage. In addition to ordinary techniques for protection from construction debris used by various trades, temporary protective window films may be applied to glass. Follow specific manufacturer instructions regarding film application and removal. If the film is removed prior to job completion, additional cleanings may still be needed to prevent glass damage. Failure to remove temporary protective films by the manufacturerâs recommended date may result in aggressive methods being required to remove the film.
Glass that isimproperly stored orleft unprotected during construction may result in glass that cannot be successfully cleaned using routine cleaning procedures. In such situations, more aggressive cleaning and restoration techniques may become necessary, such as the use of razor blades, chemical cleaning and/or mechanical polishing. Glass surface conditions that may require more aggressive cleaning techniques would include, but not be limited to, the accumulation of paint, stain or varnish overspray; mortar, concrete or cement splashing on glass; silicone sealants and/or lubricants being smeared or sprayed onto glass and frames; and sealer overspray or run-off from adjacent masonry or stone waterproofing operations. In the process of removing tenacious contaminates from unprotected glass, particles may be trapped between the razor blade and the glass, resulting in fine scratches.
in the late 80âs and 90âs on tract homes they used to have the stucco company spray the glass with some type of waxy/oily spray, what would happen is the builders clean would consist of laborers using gasoline and metal painterâs putty knives to scrape the goop off, talk about a mess!
the gasoline would then kill the sealed IG units (which were just starting to become a standard on tract homes out here) and they would fog, so everyone was up in arms about not using gas (or any solvent) to remove the waxy/oily gunk, man o man try removing that stuff without a solvent! yech!
finally the gas AND the waxy/oily gunk wasnât in use anymore lol
so now that i think about it, they stopped protecting the glass and expected miracles from sloppy trades (concrete, paint, drywall) leaving stuff all over
Anderson applies film at the factory (might be a special request, not sure, cause its not on all andersen) , such a simple thing, surprised all mfrs didnât adopt this as a standard decades ago
CCU is so much better with windows like this. Except when concrete has splattered on them, and it melts the plastic and adheres to the glassâŚ
At least, Iâm assuming thatâs how it happens. Other than that, just blade or steel wool around the edges and give the majority of the glass a simple mop, and youâre golden!
yeah it has its limitations too, concrete guys should always put up that thick paper or a visquine to prevent big goops of concrete getting on the house or windows, such a simple step but they hardly do it
cause if concrete splashes up on the glass (even if its factory protected) its getting on the frames, tracks and screens as well
but hey the contractor wanted the âbest bidâ for concrete so guess what, they arenât going to âtryâ or add any extra steps to that âbest priceâ they gave, thatâs for sure mr contractor and now you cant find a window cleaner who wants to mess with it, go figure. âhello, mcfly!!, anyone in there?â
