"Also, it appears folks on here think Sunrise makes a good vinyl sliding door."

Much better quality wise than your other option. As far as the cold conducting I will let others answer that but I cannot see that being an issue.

I am NOT a fan of any blind trapped between glass. I am not a fan of blinds in general. Hard, cold appearing, and needing another treatment to look "finished". Yanked up to expose all glass? A fairly hideous"stack"

You have a norther exposure. There will never be direct sunlight from the north. There will however, be light.

Sliding doors exist in ALL climates. Even those with a 40 degree below ZERO F. temperature plunge.

I would invest in quality. Also look at the MANY lovely options available to treat sliding doors interiors in an attractive way, whether for privacy, or light control. A good sliding door is no more lacking insulating qualities than any other quality window , properly installed.

I would not opt for the "tapped " option.. jmho

As to which brand? You generally get what you pay for, in any material, and in any thing. Doors and windows included.

I never like blinds inside windows or doors when they fail they look horrible and the only way to fix is to take the glass apart. Get a door and add blinds no other choice IMO.

One way you could combat the potential cold would be to put a curtain over that area much like we did in Germany. We've had lots of back doors with blinds in the glass and didn't really notice a cold issue.

We changed out a door from a blind attached to the door that would whack every time you opened it up to blinds in the glass; it was more peaceful. Until my husband decided to raise the blinds too fast and broke it; I could never get the magnet to realign and eventually we had to get a new set. That is the downside of blinds in glass; you have to be careful and raise them with an even hand. But I would choose blinds and glass again over blinds attached to a door or hung ver a door.

In our upcoming new build I'm using curtains because the doors open up to a screened in porch that is closed in on three sides. The curtains will probably be more insulating than the blinds in glass.

A good door isn't "cold" ......

you said this room doesn't get too much sun, so I think you have your answer. sounds like you need good insulated doors way more than you need blinds.

if, later on down the line you decide you need some kind of sun blocking, you can add curtains or some other window treatment.

Hey y'all. Apparently my initial question caused some confusion. My wife wants blinds between the glass so I'm trying to understand whether the triple pane Pella with blinds between the glass (which has argon gas in between the panes without the blinds so would be more insulating) is worth the extra expense versus the Sunrise double pane which doesn't have argon gas and therefore won't be as insulating, if at all. It would be helpful to hear from someone with a sliding door or window with blinds and whether they notice that window or door being the source of a chill in the room. Thanks!

I would not use anything Pella for any windows or doors. Personally I think you will be fine with the double pane Sunrise.

Skip the blinds between the glass. Great idea but...eventually they break...every single time.

We have installs that are 10+ years old with internal mini blinds and no issues.

We have large triple pane Pellas in our sunroom, and also Pella french doors in the same room with blinds between the glass. We love the triple pane, they are incredibly efficient. Will never buy blinds between the glass again -- they are a major pain to clean. Don't know what coating is on the glass inside there but it doesn't clean like regular glass and leaves streak marks no matter how many times you go over it. The other Pella windows don't have this issue. And you have 4 surfaces to clean... like other windows there's the interior and exterior; and then --less often, but still needed -- where the blinds are: so you also have to clean the back side of the interior window and exterior window. I hate these doors. And as others have pointed out, if the blinds break, good luck getting them replaced.
