Difference Between New Construction and Retrofit Impact Windows

Where New Construction And Retrofit Windows Part Ways

What separates new construction from retrofit impact windows is usually the installation method, not the performance of the glass itself.

When a wall is still open during construction or a major rebuild, installers can set a new construction window into the framing and build the flashing system around it.

A Practical Way To Narrow The Decision

The simplest way to decide is to evaluate the current opening first, then consider code, budget, and how much demolition you are willing to accept.
