Impact Windows vs Laminated Glass: Which Offers Better Storm Protection?

The Real Difference Between Impact Windows And Laminated Glass

• Impact test approval or product approval documents
• Frame material and reinforcement
• Anchoring method and installation method
• The glass build, including interlayer and overall thickness
