I enjoyed your presentation, but have a few thoughts about possible confusion for someone watching the video.... I think that it wasn't clear to someone unfamiliar with glass options that LowE coating and argon/krypton are combined in an IG unit, and while options, they are not available separately from the dual pane requirement. It came across as either/or especially near the end at 7:50. Also at 4 minutes while discussing tempered glass breakage the short video of glass being broken was laminated and not tempered. By tinted glass are you referring to aftermarket films or actual tinted glass? The first picture shown was of an aftermarket film but samples shown in the later short video appeared to be actual tinted glass. That could be confusing for folks who don't know what to ask. Also it might be worth mentioning that LowE is significantly better at blocking solar heat gain than standard tinted glass. When you mention how many layers of tinted glass related to color/clarity I am not sure exactly what you mean. Also, "Different color tints can block different types of light"....not sure what that means either. I think it can be confusing to talk about who makes the best glass since no window companies actually make their own glass, they all bring in glass from one of the actual glass manufacturers. Same with LowE coatings on the glass. Differences arise over who makes the IG unit that uses the glass from one or another glass manufacturer.
Thank you so much for the comments and amazing insight into window glass! Those are all great ideas for upcoming deeper dive videos, so be on the look out for that upcoming content. For tinted glass we are looking at actual tinted glass. For the first image we were attempting to highlight and simplify the idea of what tinted glass is mostly used for, blocking UV rays. I do see how that can be confusing. To answer your question on colored tints affecting different lights, the main goal is to think about how glass tinted a particular color will change the light coming through it. Since sunlight is white (the sum of all colors) filtering it through tinted colored glass can change what color enters your home. For example, if your tinted glass is a color that absorbs the yellow light entering your home then your room could have a blue hue that you might not have expected when picking out your tinted glass. If you scroll to the bottom of the page linked below there is more information on glass tint color and its uses. www.provia.com/glass/privacy We wanted to make sure to mention it so you would be informed when shopping for tinted glass with your window contractor, and can ask the right questions to make sure you get what you want. Thank you again for your comments!
@@TheHomeSolutionsChannel Thank you as well for the reply. I have been retired from the glass/window industry for a few years and I do miss the fun parts of my old job, so I appreciate and enjoy the opportunity to chat with others about it. A significant part of my previous job was consulting with window companies on their glass choices primarily safety and security, but also what glass product might be most appropriate in a given application possibly related to energy performance, or sound performance, or whatever concerns they might have. So not looking at potential window replacement, but simply geeking out on glass or window related videos. And there are some shockingly bad videos full of misinformation that I have seen, but the few of yours that I have watched are well researched and well presented. I suspect that I might be preaching to the choir here, but tinted glass is identified by visible transmittance and color with the three most common residential products being 44% gray, 52% bronze, and 73% green. There are other options of course, but these are more often than not, are the ones generally found in residential applications. Although tinted glass works for blocking solar glare, monolithic tinted glass alone doesn't really match up very well when compared with LowE coatings if the requirement is to block either IR (heat gain) or UV (fading resistance). However an IG unit with one lite coated and one tinted can result in very nice SHGC performance numbers. In this application the IGU orientation often becomes a definite difference of opinion among people who specify window glass as to which lite should be exterior and which interior when used together in an IGU. In my experience I would say that more often the exterior lite is the tinted one, often for aesthetic reasons - the architect likes the look - but if limiting SHG is the primary goal then there can be some interesting discussions. Also in this application it's crucial that both lites are either HS or tempered because of the potential for trapped heat in the IGU space, especially when the tinted lite is outboard. When the LowE lite is exterior (low solar heat gain coating on surface 2) the potential for glass breakage due to thermal shock is reduced but not eliminated. And I just rambled for several paragraphs. Thanks again!
@@gregcorwin8316 I heard that when cleaning lowE glass you have to be careful not to use steel wool which would scratch the coating, but I also heard the coating is supposed to be inside the pane so you can't scratch it, and the only way it would be coated on the outside is a manufacturer error. What to believe??
@@joshuahall3622 There are two types of LowE coatings, hard coat and soft coat. Soft coat must be between the two glass lites or else it will corrode fairly rapidly. Any sort of cleaning, steel wool or not, will also destroy the coating. If soft coat is exposed, that is a manufacturer defect. It does happen but it is very rare. Hard coats can be exposed, they don's have to be between the lites. Hard coats are not as efficient as soft coats and they are much less commonly used. You might find them on storm windows and doors, or other applications with just a single pane of glass. Also there is a version of hard coat that does go on the exposed side of a dual pane called a surface 4 coating. This type of coating is used along with a soft coat between the lites to improve energy efficiency. Hard coats are tough but probably not the best idea to clean them with steel wool, especially surface 4 coatings. Follow manufacturer instructions. There are other types of coatings that might be on the glass, such as easy clean coatings on the outside that could be damaged if cleaned used metal scrapers or steel wool.
