Ah, but in North America, only double-pane windows are required. Triple-pane windows are considered necessary for noise abatement but are prohibitively expensive. There are government rebates for upgrading older homes from single to double-pane windows, but no third-pane increase in the rebate.

Yes, and to give an idea I replaced some windows in my house a couple years back. The double pane windows on the north side were about $100 to $150 per, while the triple pane windows on the south side were $900. The triple pane also had higher installation labor costs. It seemed ludicrous to me that it would be so much more expensive, but after calling around, that was very typical.

[voisin]

Why was labor more expensive?

[delusional]

Only thing I could imagine was extra hands to deal with the weight.

Don't they use machinery to carry the windows? Even double pane gets heavy. The windows of the sliding doors I've recently got replaced were like 200kg each.

Where I am, in British Columbia, the solution formoving even the biggest windows in single family homes is to use ten men and a boy.

It is exceptionally rare for a contractor to have equipment to move literally anything that takes less than four laborers to move by hand.

Not here in the Netherlands. By law anything heavier than 23kg should be carried by a machine. In principle one can carry something heavier, but then there needs to be a written plan etc.

It's very common to carry stuff with a small crane. If it needs to be carried to thd back of the house which is not accessible, they set up a bigger crane.

I got extra thick glasses (12mm thick each instead of 6mm standard) for my argon filled double pane windows in the bedroom. The noise isolation is incredbly improved. It did cost only 15% more. This is Europe again.

[UltraSane]

Do you mean the spacing between the two panes of glass?

[bgnn]

No no, the thickness of the glass panes.

[UltraSane]

12mm thick glass is pretty damn thick and is normally used for for table tops, glass walls and partitions, hearths, frameless balustrades at ground level, and kitchen worktops.
