We are planning an addition to our home and want to have long windows along the long wall. We understand that the casement operating mechanism might be questionable with a large window and was looking for your opinion on which is best and anything I should be aware of.

We're meeting with the contractor tomorrow to go over the different options/cost.

There will be transoms above the windows too to help give us the look we like. I linked to a picture that shows the look we're going for.

Here is a link that might be useful:
