What is the Difference Between New Construction Windows and Replacement Windows?

Replacement Windows

Replacement windows are designed to do just that—replace an existing window. What they do not do, however, is become part of the house itself. That’s what a new construction window is for. Replacement windows come with features that help installers place the window with more ease.  

New Construction Windows

Although your home may not be new, you can still install new construction windows. The difference in using new construction windows is that installing them requires a partial dismantling of the home’s exterior and a complete rebuild of the area around the window. However, the result is a completely customized fit, which includes secure attachment to the home’s frame. New flashing and exterior materials are required.  

The Big Difference

The difference between the two is essentially a nail fin. New construction windows have it; replacement windows don’t. Thus, there is a difference in the extent of installation that is required. New construction windows require a vast amount of work, but are ultimately more secure and probably more energy efficient. Replacement windows may be slightly less secure, but are far easier and quicker to install.
