Nice. Probably right in the same area where my brother is. He is just across from the Desert Sportmans Gun Club. How old is the home? Low-e has been used in Vegas for a long time now.

25 years. Most of the windows are definitely not Low E, and they were all hideously installed unfortunately.

If I was in your place I would absolutely consider Quad LoE-452 as my first choice, with 366 as second choice and 340 (because of the color, not performance) as my third choice.

While I am personally not a fan of the blue tint in 340* coated glass, I do know that there are many people who absolutely love it. So at some level it depends on personal preference.

*edited from 452...sorry for confusion.

Per 452, here are the relevant stats from the Cardinal Technical Glass Guide:

LoE 452 is alive and kicking and while I know that it's available, I have no idea concerning pricing compared with other coatings.

I suspect what's happening is that building a new LoE coating line to produce 452 would probably cost upwards of $20-$25 million just for the production line and not including building and facility construction/upgrade costs. Plus coating lines aren't something that is "off-the-shelf", so actual construction of the line(s) could be a multi-year project.

Another option is upgrading current lines to manufacture 452, probably in the neighborhood of $5-$10 million, but more importantly upgrading an existing line means that that line needs to be taken offline for the upgrade and during that time it won't be producing any coated glass.

While I certainly don't know for certain, I suspect that this may be why there is more limited availability of 452 at present....but it is available if not as readily as it's counterparts.

.

That is where I'm thinking as well oberon. If only we can get the 452. Window company I'm working with is checking into it. From your experience, if we can't do 452, do you think a laminate with 366 will give us almost the same U factor and SHGC? And do you know if windowed swing doors can use 452?

All three coatings mentioned can be enclosed in a laminated glass construction.

When the LoE coating is inside the laminated glass (coating against the interlayer), then the SHGC is unchanged versus a standard LoE coated IGU, but the usual U factor performance improvement of the LoE coating is nullified. The U factor would be the same as if it was in an uncoated lite.

If the coating is on the exterior of the laminated sandwich (but inside an IGU) then the U factor and SHGC are no different than from a non-laminated IGU.

Simply laminating glass does not improve either U factor or SHGC.

There is no reason that 452 can't be used in a door as long as the door manufacturer offers the coating.

Understood - thank you for that! Does the lamination increase the 366 UV performance from 95% to the 99% of 452? I saw a video where this gentleman put some beads that respond to UV light (they glow) in front of tempered glass and then laminated glass. The beads didn't respond at all when behind the laminated. I know most folks use laminated for security, safety, and storm purposes, but I thought perhaps it would bump our 366 to 99% like the 452, with security as a bonus. I say this only if for some reason we aren't able to get ahold of the 452. Do you think we'll get that benefit? And if so, worth it?

Oberon, I could kiss you. Yes, my intent was UV blocking to reduce fading. I did not realize that the VT would also cause fading! Thank you so much for that. SHGC is also important, but honestly all of these windows are much better than what we have now. However, view supersedes SHGC enough that 340 won't be our choice. Given that table, I think our best bet is still to go 452 to maintain the view and balance the UV, SHGC and fading. Most of our neighbors all close their west facing blinds 24x7. It's been a rare occasion when we toodle by to see one open. The view is a big part of our love of this home, and so we're trying to do our best to minimize damage so we can maintain that view. I use 303 spray on wood, and the living room chairs utilize Sunbrella fabric, but I have a leather couch I pull a couple blinds down to protect. Sounds like I may have to do that still, but overall much better protection. Do you think the lami addition is worth it? I'm thinking yes. I think they said it's like $275 more per window.

Goodness you have been such immense help. I can't tell you how much I appreciate you. I'd love to treat you and your family to dinner. I don't use Houzz regularly so unsure if I can message you or not. I'll try to figure it out heh. Thank you!

He is a gem.

And yes...VT will fade. An often overlooked reality when UV is fingered as the culprit.

For the record, he loves helping people as most of the contributors on here do. If you really want to get in touch with him, you can email me (enovotny@windowsonwashington.net) and I can forward your email to him.

Thank you for the offer WoW. I sent him a direct message.

In response to the window conversation - The window company gentleman that came out says they use Cardinal glass. When he called into his office he asked them to look at certain companies like Simonton when he was looking at certain windows. We have some very large joined 3-picture windows for the view, plus glass swing doors, etc. The swing doors seem to be somewhat problematic. We were told when looking at the 340 that we couldn't do 340 swing, only slide. I think we'll be able to do 366 swing.

Previous owners have replaced some of the windows, but the installation of most of the windows is egregious. I'm very thankful that the gentleman we're working with also noticed the poor workmanship so that our expensive windows hopefully will be installed correctly.

It sounds like lami only if we want the added security and noise reduction, etc. I know lami is much heavier and worry about sliding windows. Are they harder to open or do the frames warp due to the weight? I'm hoping to be one and done with window installs on this house hahaha!

Wow, and thank you very much! And as WoW said (thanks Eric!!), like the other pros who post here, I really do enjoy helping people to the best of my knowledge and ability. People often start out thinking "how hard can it be to buy windows?", often times turns out it can be a lot harder than people think. Getting an idea of all the different products and options available sometimes leads to information overload and the thought of where to go next.

Lami can be a great addition to a window system and might be well worth the additional cost if it is warranted by the return on investment. Not necessarily a monetary return, but a return in the areas where laminated glass excels. For example, using lami only to help block harmful UV when you are already installing glass with a UV blocking coating is probably not worth the additional expense, but when you add in additional security, big upgrade in safety, and potentially the best sound blocking available in a window glass system, then it begins to make a lot more sense.

Could you post a picture of the wall? That would make it easier to suggest window ideas/options knowing what it is that you are dealing with.

There are many walls. =) I will send you the photos in messaging for privacy concerns as photos would give away my location.

okay

Did you end up with LoE452 ? Would love to see some photos.

We did! We did the whole home in Anlin Del Mar with Cardinal 452. Project is just finishing up and painting will commence in another week. Very happy with them. Is there a particular aspect you want photographed? My view would give away my location but I could try to figure something out. Most windows were frame pulls, but some in front were jumped.

Great choice, and looks amazing from inside and outside.
