Key Installation Standards for Impact Windows
Impact windows must meet large missile impact and cyclic pressure standards such as ASTM E1886 and E1996, documented by a product approval or evaluation report.
Order windows with DP ratings that meet or exceed the calculated wind loads for your address and elevation.

Measure the egress opening of the new frame and hardware set, not just the rough opening.
You may also have a separate energy inspection or paperwork review to close out the permit.
