What impact-resistant means
Impact assemblies commonly use laminated glazing intended to remain held together after breakage, but impact performance belongs to the tested assembly, not “strong glass” by itself. Tempered glass, security film, and approved impact-rated laminated systems are not interchangeable.
Impact windows versus shutters
Impact windows provide passive opening protection because they do not have to be deployed before a storm. Approved shutters may be a lower-cost option but require storage, maintenance, and correct installation before an event. Neither approach should be described as storm-proof.
Florida documentation to compare
- Current Florida product-approval number and impact status
- Exact model, size, glass option, frame, and anchoring substrate
- Positive and negative design pressure
- Approved geographic use and installation limitations
Are impact windows required in Ocala?
Impact windows are not required at every property in Ocala or Marion County. Requirements depend on the project address, applicable code, building conditions, wind criteria, and scope. When they are not required, homeowners may still consider impact-rated products for added opening protection.
For standard replacement choices, installation scope, and styles, begin with the Ocala residential window overview.

Common questions
Can impact glass still crack?
Yes. Its purpose is to resist specified impacts and help keep the opening protected. It is not marketed as unbreakable.
Are impact windows required everywhere in Marion County?
Requirements vary by project location and applicable code criteria, so the property address must be checked before products are selected.
Do impact windows eliminate the need for shutters?
An approved impact-resistant assembly may serve as opening protection where accepted, but the exact product and installation must meet the project requirements.
Are impact windows also energy efficient?
Some are, but impact approval does not establish energy performance. Check the separate NFRC ratings.
