Hello
What is the difference between low e II w argon and loE 366 with argon? Cost? Quality?
Thank you!

The 366 is much better at blocking radiant heat. Basically, the same U value but lower SHGC to be technical. Cost is minimal (between $1 and $1.50 a square foot as I remember). Quality is the same as they are both Cardinal products.

Thanks. From what I gather 366 is slightly better for slightly more.

eastbay10 summarized it perfectly.

Glass recommendations depend on location, orientation, and customer goals.

Here is more info on location of home

West facing home
4 seasons climate
Michigan

Based on this does one make more sense for us?

Low-e 272.

RE: Glass type difference- integrity

Thanks windows on washington. Why Low e II? You also mentioned "customer goals" as a consideration. Please elaborate.
THank you.

Michigan is a heating degree dominated climate.

This being the case, Low-e 366 has a lesser SHGC and you will block some of the "free" passive solar heating you get from the sun in the winter.

Low-e 366 is more well suited for homes where the balance is more 50/50 or weighted towards the cooling season.

RE: Glass type difference- integrity

Thanks. Is one more expensive?


 o
RE: Glass type difference- integrity

Not usually.

If anything, the Low-e 366 might be billed as a bit of a premium.

+1 to WoW's recommendation. 366 is not ideal for a northern climate, the 272 should actually be more efficient for you despite a slightly higher u-value. Price depends on manufacturer, some are higher for one than the other depending on what is standard. I have never ordered 366 in Marvin, so I don't know whether it is higher or lower.

RE: Glass type difference- integrity

I would argue to take it one step better. Specify their low e 180 on the south facing windows, low e 272 on the rest. According to my rep, 180 and 272 are the same price, 366 is slightly more. A typical window is $15-50 depending on size in 366.

Thanks for all the input. I have decided on the Lo E 2 glass. I was originally quoted on this glass but then window rep changed it to lo e 366 when we we're trying to bring costs down. This is counter to what the feedback has been in regards to costs (366 premium)....


 o
RE: Glass type difference- integrity

Low-e 366 is more expensive about 99% of the time.

It is 3 vs. 2 coats of Low-e. Merely from the consumables aspect, there is more metal oxide in the Low-e 366 so there should be more expense. Not sure how your dealer is quoting stuff but a majority will bill the Low-e 366 is a premium, if only slight.

RE: Glass type difference- integrity

I had a few quotes on a wood project recently and 272 was a premium over 366 in the Windsor line... I'm not a huge fan of that window anyway, but I thought it was the craziest thing. They said it(366) was their standard offering so it was cheaper.... Or maybe my rep was just full of beans, lol.

366 costs more to produce, but it could be cheaper through a specific window company if they stock it as standard (major efficiency boost when it comes to IG production)


 o
RE: Glass type difference- integrity

+1

Definitely more expensive from a production standpoint but if they stock a bunch of it, it will drive the cost down.

Here you are oberon, this should explain it. Apparently a new feature (found it on the computer help forum).

Here is a link that might be useful: Picture upload


 o
RE: Glass type difference- integrity

That link doesn't explain how to upload a picture. Where can I find that info?


 o
RE: Glass type difference- integrity

actually there is a button directly above your user name when posting a follow up for uploding a picture.


 o
RE: Glass type difference- integrity

Cool, I didn't see it before.


 o
RE: Glass type difference- integrity

Doesn't work on an IPad. :(

RE: Glass type difference- integrity

Cool and thanks!!
