Impact Resistant Windows & South Florida Building Code
Significant code changes have been made in recent years in response to hurricane damage, requiring building envelopes to be more weatherproof and impact resistant. The damaging effects of extreme winds and flying debris have been so widely documented that the entire Atlantic Coast has been declared a hurricane-prone region.
In 1992, shortly after Hurricane Andrew, South Florida enacted the first hurricane-resistant building codes and standards. Following the devastation, engineers discovered that the vast majority of the damage was caused by windborne debris and fluctuating pressures. They concluded that the “single-gust concept” of design was inadequate to protect against sustained, turbulent winds, which is exactly how Hurricane Andrew caused so much damage.
Based upon these findings, new codes were developed with the intention of reducing the damage caused by hurricane winds and flying debris.
The original test standards or protocols: TAS 201, TAS 202, and TAS 203 were developed by the state of Florida. After that, ASTM developed two standards, E1886 and E1996, which have actually been adopted by the American Society of Civil Engineers (ASCE) and the Intl. Building Code (IBC).
ASCE 7 says that only buildings constructed in designated “windborne-debris regions” (which are clearly outlined) are required to have impact-resistant glazing to prevent wind from entering the structure, or be designed to withstand increased loads resulting from internal pressurization.
Testing Impact Resistance
For a glazing product to qualify as impact resistant, it must be demonstrated through various tests test, that the system meets specific standards:
- Impact with projectiles representing windborne debris – either large missile (projectile is a 9-pound, 2×4 timber) for systems in the lower 30 feet of a building, or small missile (projectiles are 10 2-gram steel balls) for systems 30 feet and above.
- Followed by cyclic structural loading (9,000 positive and negative static pressure loads) representing fluctuating wind pressures.
Products are qualified based upon their ability of three test samples to resist large- or small-missile impacts, or both, without penetrating the inner plane of the glazing infill, and resist the cyclic pressure loading with no tear longer than 5 inches and wider than 1⁄16 inches through which air can pass. Test reports or product approval documents indicate a description of the test specimen and components, the maximum size, the pressure rating, and type of impact for which the product is approved.
Some Common Glazing Materials
- Traditional PVC laminated glass – good for small-missile impact-resistance
- glass-clad polycarbonate / PET laminated glass – good for large-missile impact-resistant systems.
To Retrofit or not?
It’s not always practical for existing window/wall frames to be retrofitted and be certified as impact resistant. Nevertheless, it’s far more cost effective to replace the entire unit with pre-tested, rated, and approved systems.
