First real cold weather of the season live in raleigh nc. . Had okna 500s installed last fall. When i place my hand on the sill at the bottom of the window i can feel cold air. And the interior glass feela cold. Is this normal? Does okna have territory reps that can come out to check quality of tje installation?

The first call should be to your installer to have them check all details for you.

The dealer/installer can ask Okna rep to schedule a visit if needed.

+1

Start with your installer.

Keep in mind, when the ambient air temperatures (especially under heavy winds) are cold outside, you windows are still going to feel cold to the touch. General rule of thumb is that a good insulated window will have a surface temp for about 45-52 degrees when it is freezing outside with some wind.

Feeling air come through is another thing vs. surface temperatures. Some air must and will come through as the window is still an operable component.

Many homeowners are under the misguided impression that their window should feel like the walls that are adjacent to them and it just isn't the case. If in the comparison of a good triple pane window, the adjacent wall will about 2X as thermally resistant.

In the case of a double pane window, about 4X.

Good advice above. Get the installer out first. One thing that we see from time to time is after the new, airtight windows are installed, any leakage from around the old window frame (in a pocket installation) can be noticed. Removal of the casing and adding some foam or caulking takes care of that. Its not something included in a typical pocket install and may or may not even be the case, but its a possibility... The other possibilities of course would be a defect in product or install, or simply expecting a little too much as WoW alluded to. Either way, some inspection and testing as needed should be able to get to the bottom of it and provide evidence one way or the other.

You mentioned its at the bottom near the sill. This can easily be emanating from the wall just beneath the new window. Many times, walls arent fully insulated. As homesealed alluded to, removing the existing casing can sometimes necessitate insulating under the moulding.
That would certainly be an additional upcharge as its kind of a quasi new construction install at that point and not something performed with a replacement application.
Most of the time its not needed but every now and then it could be an issue and only done when it is specified in writing due to the extra cost associated with it.
Its possible that some caulking under the stool could solve it as well.
