How It Works
1. A homeowner activates the Quick Cover system as he evacuates, setting off a semi-explosive chemical reaction—like the one used to inflate car airbags—to unfold fireproof fabric from a cupola onto the roof.
2. Two large fans, like those used to blow up a children's "bouncy castle," pump air into airtight, flexible tubes that form an exoskeleton.
3. As the exoskeleton inflates, the fabric cover unfolds along the roof and over the sides of the house. The fans keep the exoskeleton rigid and the fabric taut and secure, even in strong winds.
