Complete guide to impact-resistant glass for Miami-Dade HVHZ. Compare laminated, insulated, and multi-layer configurations with interlayer specifications and NOA requirements.
Side-by-side specifications for HVHZ-compliant impact glass types.
Basic protection
Most common choice
Enhanced protection
Miami-Dade HVHZ requires impact-resistant laminated glass that passes both large missile (9 lb 2x4 at 50 fps) and small missile (2g steel balls at 130 fps) tests per ASTM E1886/E1996. The glass assembly must maintain integrity after impact and cyclic pressure testing.
HVHZ hurricane glass typically requires a minimum 0.060" PVB interlayer for residential applications. Commercial and high-rise applications often require 0.090" or thicker interlayers. Ionoplast (SGP) interlayers provide 5x the tear strength of standard PVB.
Yes, when specified as insulated glass units (IGU). Impact laminated IGUs combine hurricane protection with Low-E coatings for thermal performance. This combination meets both HVHZ impact requirements and Florida Energy Code requirements for U-factor and SHGC.
Basic laminated hurricane glass costs $25-40/SF for the glass alone. Insulated impact glass with Low-E costs $45-70/SF. Multi-layer security glass with enhanced interlayers costs $75-120/SF. Prices vary based on glass thickness, coatings, and order quantity.
