Very interesting. Personally, I do not like the closed cell foam insulation due to out-gassing, but that is just me.
Any decrease in thermal bridging is a good thing.
I wonder how the studs hold up over time being held together with glue and wooden dowels?
Now all we need is a reliable R-20 or so window.

Wonder if you could achieve the same purpose by building a double wall of staggered 2x4 with fiberglass batting insulation? Or, if that's too thick, staggered 2x3's?

too thick is not a serious issue. I have an acquaintance who built a house built with 12 inch thick walls. It's a fortress. Huge R-value. Very quiet inside.

I have no idea what these cost or how good they are, but the company claims R-10 or better. www.intuswindows.com/products/windows/ |

My personal preference would be a mineral based insulation such as Roxul. Fire proof, does not absorb moisture or water, does not out-gas, can fit every insulating need and does not leave you itching for days.
Double wall framing must still be attached to and touching the exterior sheathing which thermally bridges the outside to the inside to some degree, albeit a lesser degree. There is a way around even that, but it starts getting expensive and most would consider it picking nits.
There is a product called Aerogel, which is now made from several different materials, that transfers virtually no heat at all and is super light and quite strong for its weight.
It is still quite expensive, but if they ever get the cost down it could easily be used as a filler between exterior sheathing and interior walls, thus virtually eliminating almost all thermal bridging. The only thing left that would bridge would be the fasteners holding everything together.

SO, Alpen is now Intus. When it was Alpen they advertised and R-20 window that used some type of reflective mirror technology in between glazings. They didn't always work real well.
I hate it when these companies change names faster than most change underwear.

I love windows with really wide sills. The kind that you can actually sit in and read a book and wide enough that you can place large indoor plants inside of and still have room to look out the window.
I don't think that 20" walls are too wide. In fact, they could be a little wider.

So, who makes a good, somewhat affordable insulated window? |

That, is the $64,000.00 question, isn't it.
"Affordable" being the most difficult part of the equation. Everyone's "affordable" is going to be different. I have not yet had a chance to look over the Intus/Alpen website to see what they are presently offering, but I do remember their windows being at the top of the heap cost-wise.
I have been waiting for years for the scientists to make an Aerogel that one can see through. To date, they can only produce it as opaque at best. The second that you hear about them making a version that is clear enough to see through tell me and I will be dumping every last penny into that company's stock.
Imagine, a window that you can see through, watching some clown on the other side with a blowtorch aimed at the window and you touch the inside of the flame's focal point after ten minutes of the flame beating on it and it is not even warm.
It could change the window manufacturing industry in a really big way. And possibly the green house growing industry depending on how much UV light it blocks.

There are two solutions to this problem. Companies change their names less often, or you do laundry more than once a year.
My first job out of college, I was working in a hotel and my boss was one of the best bosses I ever worked for. If you imagine Willowgirl as a hotel GM, getting everything done with polite requests, positive comments, and somehow still demanding and getting near perfection, that was this woman.
Another of her endearing qualities was that she got me, so I didn't have to hide my true self from her for long.
One Monday morning somehow the convo with my boss came around to how I had spent the previous day doing 3 weeks of laundry. She said she was amazed I had enough underwear to get me through that long. So I gave her a shocked look and said that was only two pair and that I turned them inside out after the first week.
She was appropriately grossed out and annoyed while I had a rip roaring laugh at her expense. At the end of the week as she was leaving, she reminded me that I shouldn't forget it was the day to turn my underwear inside out.
Edit: And this folks, is how a thread goes from insulated wall studs to dirty underwear in only a dozen messages.

One small caveat. The man said "change", not "wash". There is a difference (and an old joke pertaining to that). |

As to whether the silly insulation filled studs are worth the investment, should not be hard to find out. You need first to know how much extra they cost, then secondly you need to take your Harbor Freight infrared thermometer and test to see how much variation in temperature a regular wall with solid studs has between the open insulated spots and the spots where the stud contacts the drywall.
I agree that wood is not as good an insulator as foam, but it has decent insulating properties, too, and a 2x6 installed on edge is far from an aluminum bar. A house with solid wood 6" walls would be just dandy in a lot of locations. I know, I can be casual about such things because of MY location, but I think it is pretty easy to get carried away, too. There are rammed earth houses at my elevation that hardly need heating OR cooling.
At that point you should be able to detect if you have a problem that needs solving, but if not you can go ahead and wear your calculator out by inputting the cost of heat and cooling the place, and calculate from there. If your place is set up on 16" centers, you can also build the next one on 24" centers with plain old 2x4 studs if heat and cold bridging especially bothers you. Any engineer will tell you that is PLENTY strong for stick walls, and they only went to 16" to make the construction easier. If we are going to make fighting global warming more important now, we can go back to 24" centers and save the world thataway…...Joe
