Butterfly Smoke Seal

Al Shaw, president of Butterfly Safety Products, invented the Butterfly Smoke Seal. Made of high-temperature cloth, it is made to slip beneath a door to keep smoke and poisonous gases out. The barrier is meant to buy time in the case someone is trapped in a blaze without a means of escape.

The product information states that this meets NFPA 105: Standard for the Installation of Smoke Door Assemblies and Other Opening Protectives.
