RectorSeal announced the acquisition of Smoke Guard Corp. Smoke Guard® manufactures a patented, code-compliant smoke and draft control assembly that when used with fire-rated elevator hoistway doors, protects the elevator shaft against vertical smoke migration. It is made of a reinforced, transparent, polyimide film that does not burn or melt. The film edge is connected to a continuous flexible magnet. The magnet is attracted to the ferrous metal auxiliary rails as the system deploys creating a tight seal around the elevator hoistway.

The Smoke Guard Corp. originated and continues to operate in Boise, ID, as a division of the RectorSeal Corp. Smoke Guard has expanded its install base to over 12,000 units installed domestically, and over 15,000 units installed worldwide.
