I'm going to say something on this very old post. I hope everyone is happy with the choices they made on their windows and doors. So are we. We replaced all 17 windows in our house late 2022 with Renewal by Andersen (some single casements, some double and triple sliding windows) and are ecstatic with the results. Comments about trying to find windows, find a contractor (our always reliable fantastic contractor that we've used for years said no to doing the project due to the size and complexity of the windows), etc. are true. Was RBA expensive? Yes, chokingly so! BUT....the team that did the measurements, and the installation, were superb, and we could not recommend them more highly. One stop shopping as they say, We would go with them again in a heartbeat.

i realize this is a late response but still posting in case it can help you or others. Unfortunately, yes. We have them all over our new construction home and have regretted it ever since. 1) They have no support in the trades, very few people know much about them so if they are installed incorrectly or have any installation-related issues, you are on your own. Zola personnel only come out and do minimum work as they're not allowed to "install" - only tell you all of the things that were wrong with the install, to the tune of $1800/site visit. 2) If you are planning to use any smart hardware, they don't offer any U.S.-based solutions. You *could* order hardware from Europe if you can get them to sell to U.S. market but their apps and support are all focused on a local European community - not U.S. support or U.S. hours. Basically, the issue is that they are mutlipoint locking (basically triple locking doors) which our GC never told us or asked us if we approved - so once they are installed, you cannot install a smart lock to use as a guest room/AirBnB door or otherwise allow entry remotely or change codes for an exterior door. 3) Covering the Zola windows can be problematic if you don't think through how you'd like to cover the European style tilt and turn style. (Regular shades and blinds get in the way when they turn or tilt.) There are plenty of options in the UK and elsewhere in Europe where they are used to it say, for conservatory windows. (Again, our GC pushed this on us as we didn't want this type of window.) Hunter Douglas makes a "TrackGlide" product but we couldn't locate anyone at their Corporate Hqs or locally that knew anything about measuring or planning for these products. It's a great idea but we were concerned about trying to do all of the measuring and install ourselves for fear we'd waste a ton of $ if we did something wrong. 4) Their doors and windows are manufactured in different locations which isn't normally a problem *except* if you're trying to match hardware, colors, etc. They couldn't offer us hardware on our big doors to match all of the window hardware in the rest of the house. Along with this, there is a big limitation on what they offer. Their website also leaves a lot to be desired when trying to find information about colors, hardware, etc. but so are many companies so I don't hold this against them too much. But they are a far cry from a website like TruStile's. All in all, it seems Zola products are high quality products - but they're a bit before the American market is mature enough to fully support them, esp without Zola as a company appropriately building out an ecosystem for full lifecycle support. In our experience, all they care about is the GC and/or that initial sale. Hope this helps -

Hi Catherine, we used Seemray and is happy with our windows.  We live on the Peninsula so let me know if you would like to chat more.  Li-Ying

Stan, Appears to be a few things going on there. What I don't know if how they were installed or handled by any of the parties after being manufactured. Clear indications of some QA/QC issues as it pertains to the under and over length glazing beads. On the tilt latches, those can be from poor construction or handling. Windows are obviously in finished walls at this point. Did you see the home as they were being set? Did the builder bring this up to you? Any feedback from them at the time of installation?
