Heat & Smoke Vents

We offer Milcor heat and smoke vent roof doors, including the famous Big Smokey vent door, featuring double leaf construction with flat, translucent, or domed door panels that automatically spring open to release smoke and heat in the event of a fire in a commercial building or warehouse. Commercial smoke vents open only when subjected to a minimum of 30 psf uplift pressure from within, or when activated by the parting of the UL Listed 165ºF fusible link that locks both doors into the full open position for maximum heat and smoke release.


Milcor heat and smoke vents are available in a wide range of standard double door sizes for new construction projects, and are available upon request in custom sizes for retrofit or remodeling projects to fit into an existing roof opening. Milcor smoke vents offer full, weather-tight gaskets and feature thermal efficient door panels that reduce both heat loss and heat gain while preventing condensation buildup.
