No they aren’t the same. Replacement windows and New Construction windows are made differently because they are installed differently.
New Construction windows are installed prior to the siding and trim installation. The window is attached via a flange to a prepared opening in your wall. Your homes siding and trim are then installed over the window flange.
Replacement windows are installed inside the frame of your existing window. Your old windows sash’s (the sash is the sheet of glass and its immediate frame - It can be mobile or fixed) are removed and the new window is inserted into this area. The method of installation means a replacement window will always have a slightly smaller finished glass opening.
If you are installing windows in a newly built home, an add-on or have a renovation that removed all the siding on your home it’s not even a question. You install New Construction windows. But if you are only replacing your old windows then you have to decide which type of window to get.
New Construction windows, as may recall, need to go under the siding. That means that the trim and siding around the window will need to be removed. Depending on the type of siding you have it can be difficult, time consuming, costly and may leave obvious signs that the exterior of your home has been modified. Replacement windows, although smaller, can be installed quickly and don’t require your siding, trim and moisture barrier to be disturbed.
