I have an old home in Winnipeg, Canada. Typically it gets to 40 below in the dead of winter. We use triple pane windows. I have both double hung and crankout. I prefer the double hung as they are easier to open when it's very cold.

No matter how cold it gets you still need to open windows for a few to air out the home. The brand we use is dependent on the current sales. We use wood windows with aluminum cladding.

I agree the casements work better in wind but they are a bear to open in the cold. I have one casement in the office area. and if the track freezes with snow and ice the window refuses to budge. If the double hung freezes I can get a putty knife under it.

And yes a former New Jerseyite living in Winnipeg. Nice to see a fellow Canuck here. Winnipeg was the start of the polar vortex and located above North Dakota. It's colder then Mars here which is the planet 4th from the sun (in the interest of not shortchanging the Martians). Winnipeg is the only large city in the world that's this cold.

Insulation is important too. We just redid the attic with R-60.

They used to call it an Alberta Clipper here in Minnesota but now it's a Polar Vortex. Aren't we supposed to be the 11th province?

Anyway we have the casement type. I don't think I would do casement again. Don't skimp on the windows is my advice.

Good luck!

I live far away from you guys, but here (Louisiana) I also have a slew of Anderson casements. I think my problem with them is that they run down the length if the house and they are 2nd story windows. Meaning, the tracks a a bugger bear to clean and as the home settles, they can be a bitch to close. So while I love them, I also get really peed when we get your weather...so it's take off the screens, and usually someone on a ladder outside lifting the individually hung casements to close. Some are doubles, but point is if it's a long run of them, my experience is that they can get out of kilter, so I would
go with double hung.

lart123,
All of our Renaissance solid bronze windows & doors come with triple seal glass and double weatherstripping, although we do not currently offer a thermally broken unit.
With the narrow profile of our bronze, the glass and weatherstripping can have a greater impact on the overall performance of the window.
All windows and doors are rated with a solar heat gain co-efficient (SHGC) and U-factor, so you could check those requirements for your project.
