Maybe a bit of info as to what is so special about these doors. They look to me like doors you could easily get in NA

"European style interior door" sounds like an excuse to charge more money.

Good question. The primary difference is the fit and finish to the frame. The margins are consistent and the doors fit flush to the frames. I have yet to see anything from NA that comes close. Please provide recommendations if you're aware of specific brands; would much prefer to deal with an entity from the U.S.

" is the fit and finish to the frame. The margins are consistent and the doors fit flush to the frames. ".

That is a little confusing. Do you have a detail? Sounds more like an installation issue than manufacturing.

A percentage of the difference could be attributed to installation. Using automotive as an example, there are differences between brands when it comes to body panel fit and finish. Some of it is installation, but the balance is the design of the system vs. discrete components. One can only overcome so much if the underlying design is limited.

Have the framing and doors done by a local woodworker?

My doors aren't "European" but the same guy who did all of my custom cabinetry also did my doors which have a somewhat unique style. I am sure if I had shown him a picture of those doors, he would have been able to duplicate them as he also made a very intricate elegant dining table for me based on a vintage French Art Deco table I fell in love with.

You are describing $$$$$ architrave free installation techniques, not the raw materials of the doors. Find the most expensive finish carpenter that exists locally, and ask who was his mentor. This takes a huge amount of skill, as well as the choice of the correct trimless jamb system. It has nothing to do with the doors.

To clarify, we're not looking for a jambless system; we are looking for a well designed door + frame system. Is there a U.S. equivalent to the options below? If anyone has used tilt/turn windows vs. traditional double hung, it's a similar difference in fit/finish/performance. Maybe the folks at ProVia would enter this market as a compliment to their exterior doors? Or maybe there's a already a company from the U.S. that has yet to be discovered?

Probably not but find a custom door shop. Kerfing is common for trimless drywall metal but not typically used in the US for wood casing. We bisket a lot of trim mitres (site built mortise & tenon), but not the trim to jamb.

Recommend staying with US style components unless you're able to find a carpenter experienced with the offshore system & expect to pay more for the labor.

If your budget is generous $1000+ opt for thicker hardwood jambs, 1-3/4" doors and ball bearing hinges. Not at the typical HD store. Someone will have the laminate wood look shown. I've seen in commercial but not residential.

Tilt/turn windows are US available but simpler functions rule the prices. Most clients with tilt/turn money are focused instead on multislide doors.

Thanks, Jeffrey. Interesting that German cabinets and windows have been approximated by U.S. companies (Plato/Marvin/Kolbe), but interior doors have not. Much room for improvement over current offerings here now.

I like these doors and they are made by Masonite.

IMO this is still not about the doors it is all about the casing so find a good wood worker/ installer and get that look with a NA made door.

Masonite Doors are sole thru a millwork distributor who buys typically 11/16" jambs from another supplier. The millwork distributor machines the door and the jambs applies the hinges and ships it out. This is in no way comparable to what the OP is posting about. You would need to go to a custom shop (Select Door, Fonterick or similar) who would manufacture the door and the jambs. The tolerances and quality control would be much greater than the basic millwork supply house prehung door.

Thank you for offering up an option, Beverly. It's a step closer to the objective, but still not a system that includes the frame/jamb as pointed out by millworkman.

The doors from Lebo/Sarto are fundamentally different in that they're "rebated." There's a portion of the door that fits inside of the frame/jamb and a portion that extends beyond the opening.

The doors I posted are not like the European doors but they are not the same price either. The doors are available Prehung including jamb and trim & are available hollow or solid core and in two thicknesses.

You are speaking of a RABBETED door frame. In todays age most all exterior doors are a 5/4" jamb with a rabbeted stop. As I said those are millwork shops not a distributor making those. You could also try TruStile.

Thought I had read "rebated" in the documentation...

Great recommendation re. TruStile - thank you.

Maybe they call it rebated in Europe, not sure, I have always heard it referred to as rabbeted in my 40 years in the business.

TruStile doors are a subsidiary of Marvin. I belive they are made in Colorado and I think they could have what you are looking for. Also, any city I have lived in has a large reputable lumber comany that can order or have made almost any door you are looking for. I like to purchase made in USA when I can and found that doors are an easy USA item to source.

Here's a general door video with good info.

"How to buy doors that don't suck." Spend money. It's always the answer to how to elevate any build with high end choices.

Not always. He had his finish carpenters build some doors. Solid wood S4S is not that challenging as a diy. Quality at a much lower price than $1k/door.

Thanks for forwarding the video, Dan. Been following Matt for years and his timing could not have been better.

This vendor is on houzz.

Reached out to Angelbau yesterday, will keep everyone posted on the experience. Interesting door, frame, and trim offerings on their website.

It's still early in the quoting process and there's a fair amount of work remaining to optimize the configurations to acheive our budget. That said, working with Dusan at Angelbau has been very positive. He knows the product lines inside and out, having installed it in his own home. Will share additional details as the process continues. Thanks again to Jeffrey Grenz for the recommendation.

Getting close to wrapping up the final quote. We're extremely impressed with the product options from Angelbau and Dorsis. Dusan has been outstanding to work with from Day 1. He's answered dozens of questions and provided detailed installation instructions. Our builder had a few specific concerns regarding the drywall-to-frame attachment methods, so Dusan hosted a video conference and addressed each item without hesitation or ambiguity. Having built a few homes, this level of professionalism is indeed an outlier.

Order placed on 15-Aug-22 for 26 doors and frames. The color match sample we received for the doors was a perfect match and we're looking forward to seeing the doors in person.
