Hurricane Resistant Glazing Systems & Storm Codes
Southeast Texas building owners know that hurricanes are a matter of "when," not "if." When a major storm hits the Houston area, high winds and flying debris put intense stress on building windows. If the glass fails, the sudden rush of air into the structure causes a massive build-up of internal pressure, which can blow off the roof. Hurricane-resistant impact glass is designed to prevent this envelope breach.
Glazing Science & Storm Engineering
Impact-resistant glazing consists of a heavy double-pane unit with a specialized, thick structural polymer interlayer (typically PVB or ionoplast SentryGlas) laminated between the glass layers. In laboratory tests, this glass must withstand direct impacts from a 9-pound 2x4 lumber projectile fired at 34 mph, followed by 9,000 positive and negative wind pressure cycles. Even if the outer glass layers crack, the interlayer remains anchored to the frame, maintaining a water-tight seal.
Weather Protection Priorities:
- Wind Load Engineering: Framing systems engineered to resist high negative and positive pressures.
- Solar Heat Control: Microscopic metal oxide coatings that bounce away solar heat.
- Acoustic Isolation: PVB membranes that dampen noise from traffic and severe wind.
