Can I replace the existing glass on my windows and doors with impact glass and get the same level of protection?
NO. An impact window is a combination of a strong frame, impact glass, secure method of attaching the glass to the frame and a strong method of attaching the framing to the structure. While the glass may be able to resist the impact, the window framing will not be able to hold the glass in place. This type of upgrade is not recognized by any building department or insurance companies.
