Wild Winds and Rolling Waters
by Aaron Hoover
Despite months of front-page Hurricane Katrina news coverage in 2005, building codes and enforcement practices continue to vary greatly. Moreover, surprisingly little is known about how hurricane winds pull apart and drive rain into homes — and what affordable measures can seal them tight. Plus, existing homes — which comprise the majority of the coastal housing stock — may have few (if any) of the hurricane protections standard in new homes. Fortunately, a small community of building scientists at universities and in the public sector is working to close at least some of these gaps. As Aaron Hoover reports, current hurricane research points the way to practical improvements for coastal homes.

Gable-End Retrofits
by Richard Reynolds
A couple of decades ago, not much was typically done to secure gable-end trusses: at most, a few toe-nails, perhaps an occasional strap or diagonal brace. But these measures prove insufficient in a high-wind event, where negative pressures are the most likely forces to pull apart an underbuilt wall. And once the gable end goes, it can unzip a house, devastating the structure and ruining the entire contents of a home. As Richard Reynolds explains, retrofitting gable ends to resist hurricane-force winds must not only brace the framing members but also strengthen the connections. Here, he details the five-step process that results in a well-secured, well-sealed gable-end retrofit.
