Another thing that differs between replacement and new construction windows is the cost.
Difference between new construction and replacement windows.
You might think that new construction windows come at a lower cost since they re not the same quality as replacement windows.
Unlike replacement windows new construction windows need to be installed on the framing directly with the use of a nail fin frame.
New construction windows are used when a brand new home or a new addition to a home is being built.
Replacement windows could still be used but new construction windows are often more substantial and will not reduce your view.
New construction windows are meant for clear openings in the house usually with no trim or siding in place.
Replacement windows replace existing new construction or replacement windows.
New construction windows have nailing or attachment fins or flanges on the exterior side of the window.
Replacement windows have no nailing fins or flanges.
New construction windows are built for new homes or home additions.
Because replacement windows fit inside the existing window frame you end up with less glass therefore a smaller view.
