All code approvals for impact windows are not created equal. Code approvals can be granted for many different product types, product properties and product uses. When evaluating code approvals, make sure the products are specifically approved for impact by a reputable governing agency (such as Miami-Dade County) and verify the approved performance levels (PSF). Some manufacturers misrepresent their products as impact approved, when in fact the product is not. Beware of the following:
- Approved NON IMPACT windows and doors
- Impact windows and impact doors that are NOT approved for larger sizes, heights or locations in a structure
- So called “impact products”, which are simply impact glass in a non-impact approved window. Under tropical storm conditions, the glass could fly out of the window framing.
