Very good presentation on some of the differences between tilt/turn and double hung windows. While both European and North American window manufactures offer fixed or picture windows, a typical larger North American window company is almost certainly going to offer variations of at least several different types of casements, plus awning, double hung, single hung, several types of sliders, hoppers, and often more types and styles of windows. The typical European window manufacturer on the other hand offers, in addition to fixed, tilt/turns, which is actually the correct (at least on our side of the pond) label for what people often refer to as European windows. This style is also sometimes referred to as dual action by some manufacturers. There are of course several different reasons for why North American companies produce many different styles of windows versus what typical European companies produce, and while there are MANY small window companies in North America that do limit their production to only two or three different window styles, some of the basic differences in manufacturing philosophy include government regulations, geography, and customer preferred aesthetics. These are all major factors in the differences between the product lines offered on both sides of the pond. The widespread use of European when describing this style of window tends to make people who are at least passingly familiar with the style think that they have to look to Europe to find them, when in fact, there are actually a good many companies in North America that also offer tilt/turn windows, and some of them have for decades, but the style is still generally foreign (pun intended, sorry) to most American consumers. I have 17 year old tilt/turns in my home in middle American that were manufactured by a window company in western Canada using imported vinyl and hardware, but glass and IG components from US, and they are every bit as good (better than some) as anything manufactured in Europe performance-wise.

American windows are crappy. European windows hands down!

Put the blinds inside the double window

How do you want to clean the American window from both sides?

The term "European" is kind of missleading, because there are different styles. The "American Style" is originally from The UK. The other Window with the "Tilt and Turn Function“ ist a german invention by Wilhelm Frank, patented in1935. Over the last 50 years this system spread througout Europe. Inside turning windows ar commonly use in Middle and South Europe, where in Skandinavia Windows and especially appartement doors open outwards (Fire escape). In Germany (and other countries too) you can also get sliding windows (vertical/horizontal) but they serve usually a certain purpose like Ticket offices, Kiosk, Cafés etc.

finding it hard to find Hurricane impact tilt and turn windows in UPVC.. do you have any reference

American windows dont "need" the extra framing. It would add cost. And all it does is stiffen the window. A euro needs it because of how it opens.

American doors is good. But thw Double-hung is the dumbest thing I ever seen in my life. Casement, Awning or Tilt and Turn still better than that Double, Single Hung garbage.
