I'd do a little more investigation.

I had the same thought, don't you have better windows in Canada?

House is in Canada? No WAY I would ever order anything from overseas that doesn't have representation in your area. Bunch of good windows in Canada though.

I used a euro fenestration company based in the US to order my windows. It was fine. Architect / assistant / homeowners went over every detail and measurement. Crates arrived just fine and I don't think I could have gotten as nice a window as we did. I would not try to do this yourself - but a company that does this makes this seamless.

WIndows in a build like yours will make or break the design.

If this slim frame is the design you are looking for - do you have a local company that does good looking storefronts? I have a local glass company doing both storefronts and folding window walls, double glazed, thermally broken, etc.

We used Pella twice with no problems, but that was decades ago. And Pollard as well. But in more typical sizes.

From building and selling some two dozen homes, we noticed that window details weren't a big concern with buyers. And this house will be sold asap. (If we don't sell the lot first!) I've observed that there's more obsession with kitchen counters and bright shiny doodads than anything structural or functional. Just look at Houzz threads!

Build underway near us. Time to check those window stickers!

Matt was much more reliable when he wasn't a paid shill. Surprised he missed out promoting crypto currency!

I am not knocking vinyl windows in general (your two choices aside), I have vinyl windows from a Canadian company in my house, but for the look that you are after vinyl might not be the best aesthetic choice.

You might take a look at Marvin Modern fiberglass series or else Kolbe Vistalux either AL or WD as options. Fiberglass might be the better material choice for that aesthetic and performance, and as mentioned, there are some very nice (vinyl and fiberglass) windows made in Canada.

Agree about Matt, I used to like watching his stuff but not anymore, his posts are more infommercials now.

Per windows, at one time he was a huge Jeld-Wen fan, then Marvin, now he is on the "superior Euro window kick". Would be nice if he actually knew what he was talking about and not just echoing common misconceptions about Euro window tech and performance that are not uncommon on the internet especially among people who are more interested in bragging rights than actual facts.

Heck there is a video of Matt visiting a guy in a garage who makes retro single pane wood windows and when the guy starts knocking modern window performance advantages over retro single pane as not real, Matt is all in with agreeing with him.

Were money no object, Ridley or Loewen would be at the top of the list. After reviewing the class action info, which I had forgotten about, I'm checking out Marvin. Stickers gone.

As for distant suppliers, what happens when a seal goes during the warranty period? Or the bricklayers crack a window with their scaffolds? Euro sending out a crew from Boston to Taranna or Iron Mountain in the Upper Peninsula?

We had an outside pane break on our large window. Our window guy ordered us a new triple pane sealed unit with same specs (glass only) and we'll replace it ourselves. Our window supplier had gone out of business, but he had another source (Poland for glass, vs the prior Austria for windows) but he had all the specs to ensure it would fit / perform.

I was most concerned about repair/replacement during the warranty period.

If budget is an issue, why not design a 3000-4000 square foot house where you can afford to put in really nice windows, instead of a 6000 square foot house? I feel like this might be the question you would ask someone else in this forum, so I am asking you.

Exactamente!!

Much has changed since--down to a family of three from six.

But it took 4 years and 3 months to get this passed! (Only missing approval by the Ministry of Silly Walks, as M. Bischak observed.) Not young enough for that again.

I'm ready to buy a smaller cheaper* lot in a Toronto neighbourhood where we used to live (a five minute walk from Drake's palace), re-cycle one of my previous 4,000 sf plans and start in six months. But I have been over-ruled!

*a very relative term

Get bids from the supplier mentioned for European windows. You can ask what replacement under warranty entails. You may find a substantial savings for a high quality product.

...Poland for glass,...

Why would you want to order glass from Europe?

Dan, you used to be a big time Marvin fan, now you are pushing Euro windows, why the change of heart?

Poland provider could exactly match spec in existing windows. Could I have gotten it here - maybe - but frankly- it's wasn't crazy expensive to just make sure it was exact and having someone else make sure it was right (that is a professional) seemed like a good idea in a high end build.

Makes sense from that perspective because it can be very difficult matching color between LowE coatings from different coating plants, even those from the same company with identical specs.

All sounds great on paper, until there is a warranty inquiry.

Marvin Modern would fit this build. Competition from Europe could add to the quality choices. I'd expect the pricing would make a non vinyl choice a better long-term option for the op. He can get a bid for Marvin after the Euro pricing. See what the price comparison is. If he can get a competitive price from a Marvin source based on negotiating with the pricing he's getting, I'd go with Marvin Modern.

Order something local. Our windows are vinyl and only meh but from a local shop. We’ve had a few minor issues and they’ve come and dealt with them same week. Would never order from abroad. Also in Canada.

"I've observed that there's more obsession with kitchen counters and bright shiny doodads than anything structural or functional."

Unfortunately this is very true. One neighbor building near us has spent a couple hundred thousand on home automation/security, but used basic PGT vinyl windows and the "custom" division of a production builder! The same vinyl windows you see in house at 1/5 the cost.

We've bought and lived in houses with crappy windows, so putting in good windows in our new house was at the top of the list. We are very happy with the Marvin windows so far.

Like others mentioned, I think it's better to buy locally. I'd recommend checking out the local offerings like Ecoline. They offer a good range of window styles, including custom-shaped windows.
I've had my windows from them for a while now, and they're holding up beautifully. Good insulation, no drafts, and they operate as smoothly as the day they were installed.
Plus, supporting a local business has its own set of added benefits, like better customer service and often quicker turnaround times for support and maintenance.

We've (sorta) ended up with Frank by Ostaco and Weather Shield.

I say sorta as four frames installed on the first floor six weeks ago are still lacking the glass as the "stops" supplied didn't fit. Supposedly, they're available but the window installer we're contracted with is vacationing in Cuba.

Second major snowfall of the season underway now, to be shortly followed by the third. Jambs are getting damaged...let alone the delaminating plywood after each winter storm.

And without windows we can't spray foam under roof and the basement to seal the house in so inside work can proceed in comfort and safety.

Shopping local is not all it's cracked up to be.

Sorry to hear of your window woes. With delayed windows, builders in our area will often use plywood or OSB to board up the window openings and building wrap to seal the exterior so they can continue going with all the interior work. Is that an option to keep you going?

'Frank' is a good name for a monkey.

Temporarily use plywood or OSB to board up the window openings ...

I kept being told "soon". And verry large openings to cover.

Window installer finally called. As soon as the -15º-20ºC. retreats, it will be done. The glass is installed into the frames with rubber mallets. In this weather, little give in the vinyl frames and vinyl stops, so too big a risk of breakage. Next build, smaller windows! (Gun slits for the changing times, I fear.)
