You might think that new construction windows come at a lower cost since they re not the same quality as replacement windows.
Difference between new construction and replacement windows.
New construction windows are meant for clear openings in the house usually with no trim or siding in place.
Replacement windows could still be used but new construction windows are often more substantial and will not reduce your view.
Replacement windows are defined as windows installed into a pre existing window opening while new construction windows are designed for homes that have yet to be constructed or used in the instances where an existing window has to be removed down to the studs of the walls before it can be replaced.
Another thing that differs between replacement and new construction windows is the cost.
New construction windows have nailing or attachment fins or flanges on the exterior side of the window.
Only after installation is the home s exterior completed.
New construction windows are used when a brand new home or a new addition to a home is being built.
Because replacement windows fit inside the existing window frame you end up with less glass therefore a smaller view.
Replacement windows have no nailing fins or flanges.
New construction windows are built for new homes or home additions.
