One firm has an egress window that is basically a single-hung that has a sash that opens to less than the required vertical dimension, that is mounted in a primary frame that opens via a second latch so that the entire window opens in the manner of a casement. So there is a primary function to raise a window, or a secondary latch that opens the entire unit. Outside of that, the code allows a protective grille only if it is operable from the inside without key or special knowledge. So, it appears that more than one unlatching motion is allowed to achieve exit capability and qualify as an exit window.
That being said, I don't understand why a simple single-hung window that has a secondary latch to remove the sash for cleaning doesn't also qualify as an egress window. We're not limited to provide a window with "one-touch" operation, only that the required opening can be provided. Most windows now have the simple ability to easily remove both sashes. Why doesn't that satisfy the code as easily as this window that has a secondary operation to achieve compliance.
